folium; the Peruvian species, however, differs in its ternate flowers, differently 

 shaped petals with gland-tipped cilia, and glandular ovary hairs, as well as the 

 more roughened pubescence. Only 2 of the 26 examinable flowers in the Prieto 

 collection were 4-merous.

Type Collection and Locality: Camp E-4852 (HOLOTYPE NY); Ecuador, Azuay- 

 Oriente border, Paramo del Castillo and surrounding forested areas, crest of the 

 eastern cordillera on the trail between Sevilla de Oro and Mendez, alt. 11000- 

 11300 ft., 21 Aug. 1945' "Shrub in clumps, to 0.7 m. Lvs deep green, rugose 

 above; yellowish below; petiole red. Hypanthium red, calycine lobes tipped with 

 green. Corolla nigrescent, of the closed type." 



Distribution: known definitely only from the Prov. Azuay-Oriente border in 

 Ecuador, alt. 3000-3500 m. 



Azuay: east of El Pan, Acosta 5107 (F); Paramo de Matanga, Lehmann s.n. (K). With- 

 out Locality: "Peru," Lobb 230 (W). 



The Lobb collection probably came from near Cuenca. Superficially, B. fictum 

 resembles B. multituberculatum but probably represents a slightly different line 

 of divergence; the solitary flowers, sepal shape, small-pored anthers, and egland- 

 ular petals display affinities with B. ecuadorense . From this relative, B. fictum 

 may #asily be differentiated by the much larger leaf callosities, longer apical 

 ovary lobes, and recurved ovate imbricate sepals which within are tuberculate or 

 stout-strigose. 



36. Brachyotum multituberculatum Wurdack, sp. nov. 



Trichomata laevia. Ramuli novelli obscure quadrangulati cum petiolis pedi- 

 cellisque dense gracili-hirsuti pilis adscendenti-patentibus ad 1-2 mm. longis. 

 Petiolus 1-2 mm. Lamina 4.5-6 x 3-4.5 mm. ovata vel elliptico-ovata apice ba- 

 sique obtusa, nervis primariis 3 sed ab pilis occultis; supra tuberculis crassis 

 tumidis 2/mm. 2 (35-40 per lamina) in series 6 regulariter dispositis dense onusta, 

 tuberculo abrupte setifero seto ca. 0.5 mm. longo; subtus dense gracili-hirsuta, 

 pilis 15/mm. 2 et ad 2 mm. longis. Flores 5-meri conferto-terni bracteis duabus in- 

 vesti, dichasio ab foliis subtento. Pedicellus sub bracteis 3" 5 mm., super 2-3 

 mm.; bracteae 8x9 mm. late ovatae apice obtusae, supra parte tertia vel quarta 

 apicali tuberculis dense onustae sed alioqui glabrae, subtus sparse laxo-strigo-
