Fuscospora truncata (Colenso) Heenan & Smissen , comb. nov. ≡ Fagus truncata Colenso (1898: 280) ≡

Nothofagus truncata (Colenso) Cockayne (1926: 21) . Lectotype (designated by Allan 1961):— NEW

ZEALAND. Ruahine Mountain-range, October 1898, H . Hill s.n. ( WELT SP 035538!) .

Govaerts & Frodin (1999) placed N. truncata in synonymy of Nothofagus fusca var. colensoi ( Hooker 1853: 229) Cheeseman (1906: 641) . This treatment is incomprehensible and contradicts the available ecological, morphological and genetic evidence on the distinctiveness of F. fusca and F. truncata and is therefore not accepted here or elsewhere (e.g., Allan 1961, Wardle 1984, Mark & Lee 1985, Haase 1990, 1992, Dawson & Lucas 2011).

Fuscospora × apiculata (Colenso) Heenan & Smissen , comb. nov. ≡ Fagus apiculata Colenso (1885: 335– 336) ≡ Nothofagus × apiculata (Colenso) Krasser (1896: 163) . Lectotype (designated here):— NEW ZEALAND. Matamau and Dannevirke, County of Waipawa, 1883, W. Colenso s.n. (WELT SP036833a!). Hybrid parentage:— Fuscospora solandri (Hook.f.) Heenan & Smissen × F. truncata (Colenso) Heenan &

Smissen ( Cockayne & Allan 1934).

Fuscospora × blairii (Kirk) Heenan & Smissen, comb. nov. ≡ Fagus × blairii Kirk (1885: 297, t. 16) ≡ Nothofagus × blairii (Kirk) Cockayne (1911: 172) ≡ Nothofagus apiculata nothovar. blairii (Kirk) Govaerts (in Govaerts & Frodin 1999: 193). Lectotype (designated here):— NEW ZEALAND. Valley of the Dart, January 1877, T. Kirk s.n. (WELT SPO36861!). Hybrid parentage:— Fuscospora fusca (Hook.f.) Heenan & Smissen × F. cliffortioides (Hook.f.) Heenan

& Smissen ( Cockayne & Allan 1934).

Lectotype (designated here):— NEW ZEALAND. Hutt Valley, no date, T. Kirk s.n. (WELT SP036893!).

Hybrid parentage:— Fuscospora solandri (Hook.f.) Heenan & Smissen × F. fusca (Hook.f.) Heenan & Smissen. This interspecific hybrid often occurs when the two parent species are sympatric ( Cockayne & Atkinson 1926; Allan 1929). Nothofagus × solfusca was proposed by Allan (1929) for this interspecific hybrid, but this was not validly published and was preceeded by the combination Fagus fusca var. dubia ( Kirk 1889: 182) .

Fuscospora × eugenananus (Gilland.) Heenan & Smissen, comb. nov. ≡ Nothofagus × eugenananus Gillanders (2008: 56). Type:— AUSTRALIA. Woodbank gardens, Longley , Tasmania, May 2007, K . D. Gillanders s.n. (holotype HO 544640) .

Hybrid parentage:— Fuscospora fusca (Hook.f.) Heenan & Smissen × F. alessandri (Espinosa) Heenan &

Smissen ( Gillanders 2008).

Lophozonia Turczaninow (1858: 396) ≡ Nothofagus subgenus Lophozonia (Turcz.) Krasser (1896: 162) . Type:— Lophozonia heterocarpa Turczaninow (1858: 396) [= Lophozonia obliqua (Mirb.) Heenan & Smissen subsp. obliqua ].

Trees up to 40 m high. Leaves distichous, planar when evergreen or plicate when deciduous, teeth with 1–2 or 2-or-more serrations, fimbrial veins incomplete or absent; with large globular glandular trichomes on cuticle; without solitary unicellular trichome type A with a very small, unthickened base and with a large, unicellular, thin-walled trichome emerging; with solitary unicellular trichome type C with a large base equal to or greater than the diameter of the trichome and with a large, unicellular, thin-walled trichome emerging; with conical unicellular trichomes with a heavily thickened foot cell and broad base. Stomata randomly oriented; without thickened T-pieces of cuticle at the poles separating the two guard cells; usually without or one species with giant stomata over the major veins; stomata size within the areoles variable. Upper epidermal cells over veins more elongate than areolar cells or not distinguishable from areolar cells, with or without granular cell walls. Stipules not peltate. Dichasia with 1 central dimerous flower and 2 lateral trimerous flowers. Male floral meristem broadly oval, relatively flat topped. Staminate flowers with an open and broadly campanulate pseudanthium; lobes 6–14, prominent, asymmetric and irregular; stamens usually>20, centrifugal development; anthers 1.5–3.0 mm long, often curved, distal connective protrusion weakly developed, filament connective free, without epidermal papillae or with isomorphic rounded papillae. Pollen peritreme or goniotreme, mesocolpia straight to convex; colpi long, tenuimarginate, with V-shaped ends, margins not thickened, aperture> 15.0 µm long, polar to equatorial lengths ratio 0.35–0.4. Cupule valves 4; outer surface of valves with densely pubescent simple trichomes; lamellae glandular; fruits 1 dimerous or 2 trimerous.

Seven species in New Zealand, southern South America, and Australia.

Lophozonia alpina (Poepp. & Endl.) Heenan & Smissen , comb. nov. ≡ Fagus alpina Poeppig & Endlicher (1838: 69) ≡ Nothofagus alpina (Poepp. & Endl.) Ørsted (1871: 354) . Lectotype (designated here):— CHILE. Illustration (tab. 198, A, 1–10) in Poeppig & Endlicher (1838). Vázquez & Rodríguez (1999) selected as lectotype two illustrations (tab. 196 and tab. 198, A, 1–10) in Poeppig & Endlicher (1838). The lectotypification proposed here is a second step lectotypification ( McNeill et al. 2012, ICN Art. 9.17), whereby we have designated a single figure (tab. 198, A, 1–10) as the lectotype.

Lophozonia cunninghamii (Hook.f.) Heenan & Smissen, comb. nov. ≡ Fagus cunninghamii Hooker (1840: 152 , t. 7) ≡ Nothofagus cunninghamii (Hook.f.) Ørsted (1871: 355). Lectotype (designated here):— AUSTRALIA. Without locality, 1833, R. C. Gunn 178 ex J. B. L. (K000741836, image!).
