secondaries obscure above but elevated and prominently reticulate below, the 

 ends of the secondaries sometimes anastomosing to form indistinct marginals; 

 above rugose and sparsely strigulose, the hairs 1-2/mm. 2 and to about 1 mm. long 

 with the basal %-% adherent and the radicine bases abruptly expanded to 0.3*0.8 

 mm. diam.; below very densely strigulose to strigose on the primaries, the surface 

 completely covered with loosely appressed or erect hairs 35-50/mm. 2 , the smaller 

 ones almost stellate. Flowers 5-merous, mostly ternate or with an additional pair 

 at the node below the dichasial node, the persistent leaves subtending the di- 

 chasium somewhat reduced. Pedicel 0.5" 1 mm. below bracts, 2-7 mm. above; ped- 

 icellar bracts early caducous, 6-7.5x2.5-3 mm., spatulate, above glabrous or 

 sparsely strigulose apically, below densely strigulose. Hypanthium 6.5-9 x 4-7.5 

 mm., 0.3-1 mm. thick medianly, very densely strigose with the hairs to 2-3 mm. 

 long. Sepals 5-7.5 x 3-5 mm., oblong-ovate with broadly acute apices, united at 

 bases 0.9-1.2 mm., the sinuses acute. Petals deep purple, 12-20 x 8-13 mm., ob- 

 ovate and asymmetrical with broadly acute to obtuse apices, the cilia 0.2-0.8 mm. 

 and obviously gland-tipped but the glands early-caducous, outside moderately 

 strigulose 4-8/mm. 2 (densely so at apex). Filaments 3 .5—6 mm., as long as the 

 anthers; connective at anther base 0.9-1.4 mm., free of the anther 0.5-0.6 mm., 

 the ventral lobing 0.1-0.4 mm. Style 18-28 x 0.9-1.1 mm., exserted 5-13 mm., gla- 

 brous or with a very few setae on the basal V 3 . Ovary 5.5-8.5 x 3.5-4.5 mm., 

 densely strigose or strigulose on the apical 2-4 mm., the apical lobes 0.6-1.5 

 mm. above the locules. 



Type Collection and Locality: Mathews 3210 p.p. (HOLOTYPE K); "in Peruvia 

 Chachapoyas," Dept. Amazonas. 



Type Photographs and Illustrations: Gleason 88-10 p.p. (holotype); Gleason 

 28-1 and F16707 (2 different sheets of destroyed type collection of B. asperum at 

 B); Trans. Linn. Soc. 28: pi. 3, f. 33d. 



Distribution: Dept. Cajamarca and Amazonas, Peru, alt. 3000-3700 m. 



Cajamarca: between Chota and Cutervo, Raimondi 3292 (USM); Hacienda La Tajona 

 northwest of Hualgayoc, Stork & Horton 10023 (F, UC), Weberbauer 4013 (isotypes of B. 

 asperum BR, G-DEL), Weberbauer 4030 (G-DEL). Amazonas: Chachapoyas, Mathews s.n. 

 anno 1838 (BR, G-BOIS, G-DEL, K, P). 



It is quite possible that the type collection of B. radula actually should be 

 cited as Mathews s.n., and that the continental specimens are isotypes; a pen- 

 ciled line on the holotype sheet separates the holotype branch of B. intermedium 

 along with the Mathews label bearing the number 3210 from the holotype branch of 

 B. radula, 



B. radula differs from B. maximowiczii in somewhat larger and constantly 5- 

 merous flowers with markedly pubescent petals. B. asperum Cogniaux is an exact 

 synonym of B. radula Triana; the anther connective is obviously prolonged, des- 

 pite Cogniaux's assigning B. asperum to sect. Adesmiae. 



11. Brachyotum maximowiczii Cogniaux; DC. Monog. Phan. 7: 154. 1891. 



Trichomes as in B. radula. Branchlets obscurely quadrangular, very densely 

 strigulose to short-strigose. Petiole 3-5 mm. or 8-11 mm. Blade 11-20 or 30-45 x 

 5-14 mm., elliptic with the apex broadly acute to rounded and the base narrowly 

 obtuse, the 3 primaries impressed deeply above and elevated below, the second- 

 aries above obscure but below elevated and laxly reticulate although mostly hid- 

 den by the pubescence; above sparsely strigulose to tuberculate-strigose, the 

 hairs 1-3/mm. 2 with the radicine bases expanded and 0.2-1 mm. diam. and the 

 attenuate free apices 0.3-1.5 mm. long; below densely strigulose to strigose on 

 the primaries, the surface very densely appressed-hirsutulous, the hairs 25-50/mm. 2 

 with the smaller ones almost stellate. Flowers usually 4-merous (rarely predomi-
