102 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [VOL. 10 



Type: shrub 0.2-1 m, petals magenta, frequent in west escarpment savanna 

 4-8 km southwest of cumbre camp, elev. 1850-1900 m, Cerro de la Neblina, Rio 

 Vatua. Terr. Amazonas, Venezuela, Jan 15, 1954, Basseti Maguire, John J. Wur- 

 dack, & George S. Bunting 37294 (NY). 



Paratypes: Maguire, Wurdaclc, $ Bunting 37053, 37086, 37142, all from the cumbre of 

 Cerro de la Neblina; rocks on west ridge summit, elev. 1800 m, Cerro Guanay, Terr. Amazonas, 

 Venezuela, Feb 4, 1951, Maguire, Phelps, Hitchcock, 4' Budowski 31772; summit of Cerro 

 Yutaje, elev. 2200 m, Terr. Amazonas, Venezuela, Feb 17-19, 1953, Maguire $ Maguire 35321. 



T. fraterna (fig-, lip) has much smaller flowers in terminal panicles; the 

 squamules of the lower leaf surface are much narrower, with the free ends not 

 overlapping one another. T. sipapoana (Fig*, lis) lias smaller one-nerved leaves. 

 The Guanay and Yutaje collections of T. dissitiflora show relatively shorter less 

 acuminate calyx-lobes, but snbspecific separation from the Neblina population 

 does not seem justified at present.

The habit and nearly isomorphic stamens of C. aervyllacea preclude any con- 

 sideration of sect. Dicrananthera of the genus Acisanthera. Within Comolia, 

 the Neblina species would be placed in Sect. I near G. leptophylla (Bonpl.). 

 Xaud. because of the bilocular ovary and one-nerved leaves; C. leptophylla has
