the new species, but the variations of which are not included in the above de- 

 scription, is Camp E-29 (NY only) (same locality as type, ridge across the river 

 from the village of Zamora, 6,500 ft. elev.; epiphytic shrub with branches to 3 m.; 

 bracts deep pink; flowers pale pink). From the type this specimen differs in having 

 the pedicellary bracteoles only 1.5 mm. broad and consequently not clasping the 

 calyx, the calyx-lobes only 2.5-3 mm. broad, very narrowly imbricate, and more 

 copiously glandular at margin, the corolla 19-22 mm, long, the stamens about 15 

 mm. long, with filaments alternately about 2.5 mm. and 5 mm. long and stamens 

 about 13 mm. and 11 mm. long respectively. This variant seems to point toward 

 a relationship of C. zamorensis with C. capitata, which occurs more commonly in 

 the area, as noted above. The type of the new species, at least, seems to represent 

 an entity worthy of specific rank, differing from typical C. capitata in its broad 

 bracteoles and calyx-lobes and its short corolla and stamens.

Santiago-Zamora: Cordillera Cutucu, on banks of Rio Itzintza, 3,500 ft. elev., 

 Nov. 17-Dec. 5, 1944, Camp E-1201 (type US 1,989,011; dupl. NY) (epiphyte; 

 leaves deep green and shining above, paler and dull beneath; inflorescence up to 

 24-flowered; outer bracts deep red, the inner bracts pink to red; fruit white). Same 

 locality, ridge between Rios Itzintza and Chupiasa, 4,000-4,500 ft. elev., Camp 

 E-1278 (vine-like epiphyte, in tree thrown by storm; leaves deep green above, 

 paler beneath, with markedly translucent veins; bracts crimson; hypanthium turn- 

 ing cream-white, the calyx-lobes crimson). 



The remarkably developed pedicellary bracteoles and calyx-lobes of the new 

 species are so unique in Cavendishia that comparisons with other species are 

 superfluous. A tendency in this direction is noted in the above described C. 

 zamorensis, which differs from C. orthosepala in the lesser development of these 

 parts and in obvious characters of pubescence, but which may be its closest 

 relative. The new species suggests C. pubescens (H. B. K.) Hemsl. in foliage,
