64 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN' [VOL. 10 



Spathelia Subg. 3. Sohnreyia (Krause) Cowan & Brizieky, stat. nov. 

 Sohrureyia Krause, Notizbl. Bot. Gait. Mus. Berlin 6: 147-149. 1914. 



Only a single species has been described thus far in this subgenus; since its 

 original description, several additional collections have been made and these 

 furnish the primary basis for the following characterizations. 



1. Spathelia excelsa (Krause) Cowan & Brizieky, comb. nov. Fig. 1, j-m. 



Sohnreyia excelsa Krause, Notizbl. Bot. Gart. Mus. Berlin 6: 148. 1914. 



Tree 10-20 m tall, the stem tip minutely puberulous. Leaves 30-54-foliolate, 

 the leaflets with scattered glandular punctae, the petioles to 14 cm long, canali- 

 culate, deeply so at the base, minute puberulous, the rachis to about 2.5 m long, 

 puberulous, the leaflets subopposite to alternate, the petiolules 2-6 mm long, 

 minutely puberulous, the blades of the median leaflets 23-30 cm long, 3.5-5.5 cm 

 wide, narrowly oblong to lanceolate-oblong, slightly arcuate, the base strongly 

 inequilateral with both sides rotund or the upper side subobtuse, the apex 

 acuminate with the tip blunt, the costa and 20-30 pairs of primary vein-branches 

 plane on the upper surface, salient beneath. Inflorescence to 3 m long, the axis 

 densely puberulous, the primary bracts foliaceous, narrowly elliptic, ca. 20 mm 

 long, 5 mm wide, the secondary bracts narrowly triangular, about 1 mm long, the 

 bracteoles minute, the pedicels 1-3 mm long, puberulous. Sepals rotund to 

 broadly ovate, 1-2 mm long and wide, sparingly puberulous externally, ciliolate 

 minutely ; petals elliptic, obtuse, glabrous, 4-6 mm long, 2-3 mm wide. Filaments 

 (in pistillate flowers) 2-4 mm long, the basal 1-2 mm alate, the wing bidentate 

 and densely villose, shortly free at the apex from the subulate, apical portion of 

 the filament. Ovary oval, 1.5-3 mm long and wide, glabrous, the stigma sessile, 

 the gynophore 1-2 mm long, densely puberulous. Fruit very broadly oblate, 

 cordate basally, 2.5-3.5 cm long, 4.5-6 era broad, glabrous, the seed-bearing 

 portion ca. 8 mm long, 5 mm broad. 



BRAZIL: Amazonas: Manaos, Estrada do Paredao, 13 Feb 1943, Bucke 1180 (NY, US) ; 

 Oriximina, bas Trombetas, Para, Dec 1915, Buclce 15702 (US) ; Juruty Velho, Para, 28 May 

 1927, Ducl-e 30472 (US). 



The conspicuous gynophore, the sessile stigma, and the shape of the fruit 

 separate this species from its relatives in the other subgenera. In the shape of 

 the fruit and the distribution of the glandular punctae in the leaflets 8. excelsa 

 is most similar to 8. fruticosa.
