4.7-5.2 mm.; connective at anther base 0.9-1 mm., free of the anther 0.3-0.4 mm., 

 the ventral lobing 0.4-0.5 mm. Style 20 x 0.6 mm., exserte.d 3-4 mm. Ovary 5.2 x 

 3 mm., densely long-strigulose on the apical 3 mm., the apical lobes 0.7-0.9 mm. 

 above the locules. 



Type Collection and Locality: Andre 4501 (HOLOTYPE K; isotypes BR, F, 

 GH, NY, US); "apud 'Paramos' montium in Andibus Ecuadorensibus frequens, 

 altit. 3200-3800 m." Known only from the type collection. 



Type Photograph: Gleason 88-7 (isotype at K). 



B. rotundi folium is generally related to B. campanulare , B. bentbamianum, and 

 B. andreanum, but may be distinguished from all of these by the 7-nerved leaves. 



7. Brachyotum parvifolium Cogniaux, Bot. Jahrb. 42: 132. 1908. 



Trichomes smooth. Branchlets rounded-quadrangular, very densely and finely 

 rufo-lanulose. Petiole 1-6 mm. Blade 10-16x7-10 mm., elliptic with the apex 

 broadly acute to rounded and the base obtuse, the 3 primaries and the secondaries 

 obscured by the pubescence; above very densely and finely loose-strigulose 20- 

 25/mm. 2 ; below very densely rufo-lanulose, the hairs 30-35/mm. 2 and to 1.5 mm. 

 long. Flowers 5-merous, solitary on short leafy lateral branchlets. Pedicel 3 mm. 

 above the persistent undifferentiated leaves (bracteoles ?). Hypanthium 5-6 x 5.5- 

 6.5 mm., 0.6 mm. thick medianly, very densely and finely rufo-lanulose with hairs 

 to 2.5 mm. long. Sepals 5.5-7.5 x 3.5-4.5 mm., oblong-ovate with the apices 

 broadly acute, united at bases 0.4-0.6 mm., the sinuses acute, inside densely 

 fine-strigulose on the apical Petals "sulfur-yellow," 13-14 x 10-12 mm., 



obovate with the apices obliquely truncate or blunt-rounded with a small apiculus, 

 the marginal gland-tipped cilia 0.1-0.3 mm. Filaments 5-5.5 mm.; anthers 4.5-5.5 

 mm.; connective at anther base 0.8-1 mm., free of the anther 0.2-0.4 mm., the 

 ventral lobing 0.2-0.3 mm. Style 21 x 0.8 mm., exserted 5 mm. Ovary 4-4.5 x 2.5- 

 3.5 mm., densely strigulose with non-glandular hairs on the apical 1.5-2.5 mm., 

 the apical lobes 0.6 mm. above the locules. 



Type Collection and Locality: Weberbauer 4406 (LECTOTYPE BR; isotype 

 G-DEL; fragment of isotype F); "Peru: Tambo Ventillas apud Chachapoyas," 

 2400-2500 m. elev. 



Type Photographs: F16715 and Gleason 28-5 (destroyed holotype at 3). 



Distribution: Dept. Amazonas, Peru, alt. 2400-2900 m. 



Cerro de Fraijaco northeast of Tambo de Ventilla, Pennell 15841 (PH). 



Both B. parvifolium and its nearest relative, B. barbeyanum, are closely re- 

 lated to B. campanulare and B. rotundifolium, differing however in the solitary 

 and constantly 5-merous flowers, more obtuse petals, and usually 3~nerved leaves. 

 Cogniaux thought that the petals of B. parvifolium were probably purple, but Pen- 

 nell's #iotes and the appearance of the petals on his collection indicate a yellow- 

 ish color. 



8. Brachyotum barbeyanum Cogniaux; DC. Monog, Phan. 7: 158. 1891. 



Trichomes smooth. Branchlets obscurely quadrangular, very densely rufo- 

 lanulose. Petiole 3-10 mm. Blade 16-38 x 11-19 mm., elliptic to elliptic-ovate 

 with the apex broadly acute to obtuse and the base obtuse, with three primaries 

 and sometimes also 2 faint marginals on the larger leaves, mostly hidden by the 

 pubescence; above very densely loose-strigulose, the. fine hairs 12-20/mm. 2 ; be- 

 low very densely rufo-lanulose, the hairs 35-40/mm. 2 and to 2. mm. long. Flowers 

 5-merous, solitary on short leafy lateral branchlets. Pedicel 3-4 mm. above the 

 last persistent undifferentiated leaves (bracteoles ?). Hypanthium 5-7 x 6-6.5 

 mm., 0.3-0.9 mm. thick medianly, very densely rufo-lanulose with hairs to 3.5 mm. 

 long. Sepals 8-9.5 x 5.5-6 mm., oblong-lanceolate to lanceolate with the apices
