One separate piece of cuticle was prepared from debris.</p><p>HAND SPECIMENS. — KRAM P 141/5/5, 141/5/ BM, 141/6/ I, 141/6/ I / CC, 141/9/II/ B, 141/10/II/ CB, 141/12/14, 141/17/4, 141/32/4, Cia/ I /32 (cuticle only).</p><p>AGE RANGE. — Late Triassic to Jurassic.</p><p>OCCURRENCE. — Widespread in the Jurassic, mainly in the Northern Hemisphere.</p><p>DESCRIPTION</p><p>The most complete specimen is an apical leaf fragment 65 mm long, with 9 pinnae. Rachis 1 mm wide (Fig. 3C). Pinnae alternately inserted, oval, with entire margins and rounded apex. Pinnae joining rachis along their whole width, base slightly decurrent, pinnae 22 × 8.5 mm at lowest part of fragment to 14 × 6 mm near apex. Apical pinnae (including separate ones) generally oval/rectangular but margins irregularly undulate, up to 20 mm long and 6-11mm wide. Venation visible in some parts of pinnae, with thin but wellvisible midrib and slightly arched, forking lateral veins running to margins. Leaves amphistomatic, with rather thick cuticle. Cell outlines irregular, cell walls straight, similar on both cuticles (Fig. 3D, E).</p><p>Upper cuticle much thicker than lower one, stomata sporadic on upper cuticle, densely scattered on whole blade on lower cuticle. Subsidiary cells (5-7) form thickened rings around stomatal pit, encircling cells commonly present. Guard cells thin and usually destroyed during maceration.</p><p>REMARKS</p><p>Since the family Umkomasiaceae Petriella is considered to be restricted to the Southern Hemisphere according to the newest revision (Anderson et al. 2019), we feel justified in labelling the family affiliation of Pachypteris rhomboidalis as incertae sedis. Describing Pteroma thomasii as a microsporophyll probably belonging to Pachypteris, Harris (1964) suggested an attribution of Pachypteris different from Umkomasiaceae (with microsporophyll Pteruchus). So far, the female organ that could be attributed to Pachypteris is unknown.</p><p>The remains from Cianowice closely resemble Pachypteris rhomboidalis in pinna shape and size, the variable margins, venation, and cuticular structure. P. rhomboidalis has been mentioned from Poland from the Early or Middle? Jurassic of the Lublin Coal Basin (Szydeł &amp; Szydeł 1981) .</p></div>	https://treatment.plazi.org/id/03F4879AA94FFC4CFF08F43BFA9B6C80	Public Domain	No known copyright restrictions apply.

Cuticle (Fig. 3G, H) of medium thickness, cell outlines irregular, stomata on lower cuticle scattered, consisting of 5-7 large subsidiary cells around small stomatal pit and forming small thickened ring above guard cells.

The fragment is small and no details of venation are visible, but the pinnule shape is characteristic for Ptilozamites . It is somewhat smaller than usually described (e.g. Harris 1964; Barbacka 1997) but fits within its variability. The cuticle is typical for Ptilozamites cycadea, with characteristic stomata and trichome bases (Harris 1961; Barbacka 1997).</p></div>	https://treatment.plazi.org/id/03F4879AA94FFC42FC1EF51CFE066C40	Public Domain	No known copyright restrictions apply.

The proportions of the segments from Cianowice fit the variability of the species, corresponding well to specimens from Russia (Kiritchkova &amp; Nosova 2012, pl. 14, figs 6-8). The small pieces of cuticle show features very similar to those from Yorkshire and Russia. Although the specimens are too small to show all the known characters, we assign the specimens from Cianowice to this species.</p></div>	https://treatment.plazi.org/id/03F4879AA941FC42FC00F118FB2F6FC5	Public Domain	No known copyright restrictions apply.

Pott &amp; McLoughlin (Pott &amp; McLoughlin 2009; Pott et al. 2016), for which an emended diagnosis was given by Pott &amp; McLoughlin (2009). Especially the cell pattern and stomata with two opposite papillae are very peculiar, but there are some differences that make full identification difficult. The first is the size of the leaves, which are about half the typical size of this species. The number of veins is much lower than in the type material, in which up to 17 were counted in 1 cm (Pott &amp; McLoughlin 2009), or even 30 (Lundblad’s specimens, described as separate species Pterophyllum compresum Lundblad (1950) and synonymized with P. aequale byPott &amp; McLoughlin (2009)). Also, papillae are lacking on the cuticle of the specimens from Cianowice. The last difference is in age, which is typically Late Triassic and Early Jurassic; here it was together with typical Middle Jurassic species on the same specimen. Despite the above dissimilarities, we here determine the leaves from Cianowice as Pterophyllum cf. aequale based on the shape and arrangement of pinnae, as well as cell pattern and stomata structure as most important diagnostic characters distinguishing this species. The leaf size or number of veins (which also significantly varies between the specimens mentioned by Pott &amp; McLoughlin (2009) and those of Lundblad (1950), and also the presence of papillae may vary highly depending on numerous ecological factors (authors’ own observations). As for the difference in age, in our opinion it does not affect the determination (Kerp &amp; Pott pers. comm. 2018); thus, erection a new species is not justified in this case.</p></div>	https://treatment.plazi.org/id/03F4879AA945FC44FF78F71EFDB56A7F	Public Domain	No known copyright restrictions apply.

Pinnae borne on upper surface of the rachis, lanceolate, with constricted acroscopic margin. Basiscopic margin decurrent, and apex subacute. Basal pinna c. 12 mm long (almost complete), longest complete pinna 14.4 mm long. Pinna width almost constant, c. 4.4 mm at widest part. Venation fine, poorly visible due to coarse grain size of host rock. Veins slightly radiating from pinna base and seeming to divide, probably 8-12 per pinna (Fig. 8B). Leaf hypostomatic, cuticle moderately thick. Cell pattern similar on both upper and lower cuticles; cells isodiametric to rectangular, forming longitudinal files. Cell walls more strongly sinusoid on upper cuticle (Fig. 8C). On lower cuticle, stomata arranged in wide bands of c. 4 longitudinal rows, separated by 2-3 cell-wide non-stomatal bands. Stomata transversely oriented, subsidiary cells large, each bearing a prominent papilla; both papillae meeting over stomatal pit (Fig. 8D, E).</p><p>REMARK</p><p>The leaf structure, especially pinna shape, base and venation, correspond well with Ptilophyllum sirkennethii described from the Lower Cretaceous of English Wealden by Watson &amp; Sincock (1992). The significant difference is in leaf size, being at least four times smaller than the English one, but the cuticular features entirely agree between the two materials. The cell pattern, stomata distribution and structure are the same. Since the species was established based on two specimens and we have only a single specimen, the possible size diversity within this taxon is unknown, but it is well known that leaf size is one of the most variable features in the genus. Because this is the only difference between the two materials, and numerous other species from this locality also show unusually small dimensions, we classify it as P. sirkennethii .</p></div>	https://treatment.plazi.org/id/03F4879AA947FC5AFCC0F6FEFD906DE3	Public Domain	No known copyright restrictions apply.

Watson &amp; Harrison (1998) suggested that at least some species could be assigned to conifers based on their association and cuticular similarity with coniferalean shoots Sulcatocladus Watson &amp; Harrison, 1998. Dong et al. (2019) demonstrated that Umaltolepis yimaensis Dong, Zhou, Zhang, Wang &amp; Shi, ovules (which is not a typical ginkgoalean organ), and Pseudotorellia yinaensis Dong, Zhou, Zhang, Wang &amp; Shi belong to the same plant (Dong et al. 2019), but they do not exclude its ginkgophytalean affinity, rather stressing the group’s diversity. Based on cuticular features and stomata structure Shi et al. (2018) linked Pseudotorellia with corystosperms, although the question of relationship was left to resolve later. Because of the above uncertainty, we treat Pseudotorellia as incertae sedis. The material from Cianowice corresponds well in all features (gross morphology, cuticular structure, presence of fibres) with the species erected by Reymanówna (1963b) from Grojec. Our determination is made more certain by the proximity of the two localities (Cianowice, Grojec); in Grojec this species is very common.</p></div>	https://treatment.plazi.org/id/03F4879AA959FC58FC20F29AFDCD6B1E	Public Domain	No known copyright restrictions apply.

All preserved details correspond well with Harris’s diagnosis and description (Harris 1952, 1977), as well as with specimens described by Reymanówna (1977) and Wcisło-Luraniec (1985).</p></div>	https://treatment.plazi.org/id/03F4879AA95BFC5CFC40F65DFDD16CE0	Public Domain	No known copyright restrictions apply.

Leaves spirally arranged, elongated, 2.2-4.3 mm long, 1.1-2.4 mm wide. Leaves on main shoot up to 6.4 mm long, up to 2.4 mm wide. Free part half or less than half of total length of the lamina. Leaf apex narrowly obtuse on terminal branches, almost acute on main shoot (Fig. 11D, E). Leaf amphistomatic, cells of both upper and lower cuticles nearly rectangular, with straight cell walls, tending to form rows . Stomata large, in single rows separated by 2-3-cell-wide non-stomatal bands. Stomatal pit surrounded by 5-6 subsidiary cells; complete ring of encircling cells common. Each subsidiary cell bearing a papilla directed inwards and overhanging stomatal pit (Fig. 11F, G).</p><p>REMARK</p><p>Kendall’s (1947) emended generic diagnosis qualified shoots with leaves of equal length and width as typical Brachyphyllum (Brogniart 1828b), but Harris (1979) allowed this generic attribution also for forms with elongated leaves, which is the case of B. stemonium (see also diagnosis in Kendall 1947). The material from Cianowice is somewhat smaller than the original material from Wildtshire, but Kendall described her species based on a single specimen, so the range of size variability is unknown. The Polish material corresponds well with Kendall’s descriptions in all aspects, both in gross morphology and in cuticular structure.</p></div>	https://treatment.plazi.org/id/03F4879AA95FFC53FC16F39BFE4569DF	Public Domain	No known copyright restrictions apply.
