Venezuela: Kunguate (Yekuana) (Aymard & Fernández 7324), Kunwatö (Yekuana) (Ang. Fernández 5266). Notes — Guatteria blepharophylla is recognizable by shortly pedicellate flowers (pedicels generally up to 10 mm long) and by petals which are densely covered with appressed, silvery hairs. Characteristically, G. blepharophylla has long-attenuate, densely to rather densely verruculose leaves. It occurs in Brazil (Amazonas, Mato Grosso, Pará, Rondônia and Roraima) and Venezuela (Amazonas and Bolívar). In Ecuador and Peru the leaves tend to have a shortly attenuate, acute, or even obtuse base. Specimens from Jenaro Herrera, Loreto, Peru are very variable in leaf shape, particularly the leaf base which shows the whole variation range between long-attenuate and obtuse.

Monocarps 25 – 50, green, maturing purplish black in vivo, brown in sicco, ellipsoid, 18 – 19 by 7 – 11 mm, sparsely covered with appressed hairs, apex apiculate (apiculum <0.5 mm long), wall 0.3 – 0.5 mm thick, stipes 5 – 10 by 1 – 1.5 mm. Seed ellipsoid, 15 – 18 by 6 – 8 mm, dark, shiny brown, rugulose and distinctly longitudinally ridged. Distribution — Colombia (Amazonas), Venezuela (Amazonas), Peru (Loreto), Bolivia (Beni) and Brazil (Amazonas, Mato Grosso). Habitat & Ecology — In periodically inundated or sometimes in non-inundated forest or in scrub savanna, often on clayey soil. At elevations of up to 175 m. Flowering: January, February, June, August to November; fruiting: March, April. Vernacular names — Colombia: Jaacu (Muinane), Jaacuo (Muinane) (Van Andel et al. 136), Jakup (Muinane) (Urrego et al. 1417, 1572), Jimogu + (Huitoto) (Urrego et al. 1785, 1979), Vara blanca (Urrego et al. 293 A). Notes — Guatteria dura is easily recognizable by densely and coarsely verruculose leaves, in which the large verrucae often form strings of 2 or 3. Guatteria dura resembles G. meliodora in many aspects, among others by the thick leaves which completely lack the marginal vein so often found in this section; G. dura differs, however, by the densely verruculose lamina, the warts often forming strings of 2 or 3, vs the sparsely verruculose lamina with warts never forming strings in G. meliodora. The distinction between both species requires further study. There is quite some variation in petal size and shape in G. dura: in Stergios et al. 9935 the petals are obovate, measuring 20 – 30 by 15 – 17 mm, whereas in Colella et al. 2145 they are very large and narrow, namely 28 – 40 by 8 – 12 mm. The only collection from Bolivia (Guillén & Soliz 3833) is aberrant by the upper side of the leaves being greyish green rather than brown.	en	Maas, P. J. M., Westra, L. Y. Th.

Distribution — Colombia (Amazonas, Caquetá, Vaupés), Venezuela (Amazonas), Ecuador (Napo, Sucumbios), Peru (Loreto) and Brazil (Amazonas, Pará). Habitat & Ecology — In non-inundated or periodically inundated forest (várzea, igapó), on clayey soil. At elevations of up to 300 m. Flowering: April, May, July, August, October; fruiting: June to February. Vernacular names — Colombia: Buutruchicu (Muinane) (Murillo A. et al. 518), Ñaatraje dujeku (Muinane) (Murillo A. 619). Peru: Bara (Rimachi Y. 3593). Note — The majority of G. longicuspis plants studied is cauliflorous. The leaves are frequently oblong-elliptic in shape. The number of minute warts on the lamina varies greatly, the leaves ranging from densely to sparsely verruculose. The equally cauliflorous G. novogranatensis from Colombia (Boyacá and Sur de Santander) differs from G. longicuspis by much larger sepals (10 – 13 mm long and 5 – 7 mm long, respectively). A third cauliflorous species, G. scalarinervia, is easily distinguished from G. longicuspis by the long petioles (15 – 20 mm long and 2 – 5 mm long, respectively). It should be kept in mind, though, that the position of G. scalarinervia within this group is questionable. For further details, see under that species. The young monocarps of G. longicuspis are often pointed (hence Fries’s epithet), but the ripe ones are rounded.	en	Maas, P. J. M., Westra, L. Y. Th.

It looks quite similar to the Amazonian species G. longicuspis, both being cauliflorous and sharing most leaf characters. G. novogranatensis differs by a dense indument on large leaf veins below (vs mostly sparsely so) and by larger sepals (10 – 13 mm long vs 5 – 7 mm long). It should not be ruled out that future research will prove the two taxa to be conspecific.	en	Maas, P. J. M., Westra, L. Y. Th.

Flowering: November to May, August; fruiting: July to March. Vernacular names — Peru: Palo yais, Wampu yais (Ancuash 469), Yais (Rojas et al. 150). Additional specimen examined. BRAZIL, Amazonas, Reserva Florestal Ducke, km 26 of Manaus-Itacoatiara Road, 8 Aug. 1995, Sothers et al. 540 (INPA, U). Notes — Guatteria pastazae can be recognized by having verruculose leaves with obscure venation and by an attenuate leaf base, combined with shortly pedicellate flowers and shortly stipitate monocarps. Guatteria pastazae shows some features of G. modesta Diels but it differs by its much shorter stipes (stipes shorter than to almost equalling monocarp length) vs stipes longer than monocarp. After the publication of Erkens et al. (2008) the present authors investigated a specimen collected a long distance from Ecuador and Peru, namely Sothers et al. 540 from the lowlands of Amazonian Brazil, near Manaus. As that collection nicely fitted in all essential features (inconspicuous leaf venation, wrinkled fruits, etc.) with G. pastazae we have placed it there. 139	en	Maas, P. J. M., Westra, L. Y. Th.

Note — Guatteria scalarinervia is easily recognized by being cauliflorous and having relatively long petioles and stipes. Unlike other species in sect. Mecocarpus, verruculae are not always evident on leaves in some collections or are clearly visible only in part of the leaves in a specimen. This deserves further attention.	en	Maas, P. J.

Furthermore, it is characterized by large, thick-walled monocarps, with short stipes up to 5 mm diam. The elongation of the fruiting pedicel is caused by growth of the part below the articulation, rather than growth of the upper part as is most commonly seen in Guatteria.	en	Maas, P. J.

Notes — This as yet undescribed species looks similar to G. hispida as to the leaf shape and the dense indument of stiff, erect hairs. It differs from the latter by the presence of a distinct marginal leaf vein, while in G. hispida the leaves do not show a marginal vein. There is scanty flowering material, only representing flowers in young stage. Murillo A. & Restrepo described fruiting material as well, but we did not see that. Altogether, it seems wisest at the moment not to formally publish a new species. Murillo A. & Restrepo (2000) attribute the collection Stein et al. 4002 (MO, U) from Loreto, Peru, to this as yet undescribed species as well. Actually, it is the type collection of G. grandipes.	en	Maas, P. J. M., Westra, L. Y. Th.
