MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 2 



Cassia grandis L.f. 



Tree 20 m. tall, inflorescence erect, flowers rose-pink, La Urbana, February 

 27, 1949, Maguire & Maguire 28984. Distributed throughout northern South America 

 and the West Indies, also cultivated. 



Cassia moshata H B.K. 



Frequent tree with yellow-bronze flowers (often in cultivation), Isla Raton, 

 Orinoco River, February 15, 1949, Maguire & Maguire 28981. Ranging from Central 

 America to Colombia, Venezuela, and British Guiana. 



Cassia pteridophylla Sandwith. 



Tree 8 m. high, flowers yellow, Rio Cuao, Base Camp, January 19, 1949, 

 Maguire & Politi 28447. Distributed from Venezuela to Brazil and British Guiana,, 

 This species was reduced to a variety of C. adiantifolia Bentham by Ducke, but 

 the differences appear sufficiently important for its retention as a species. The 

 two species are readily separable on the densely puberulent anthers and emargi- 

 nate leaflet apices of C. pteridophylla. 



Cassia racemosa Miller. 



Small tree with yellow flowers, Murcielago Falls, Rio Sipapo, November 17, 

 1948, Maguire & Politi 27310; small tree or shrub in mixed forest near Base Camp,

 banks of Orinoco River, 30 km. below La Urbana, March 14-15, 1949, Maguire & 

 Maguire 29033. Found throughout' northern South America and as far south as 

 P araguay.

 guire, Jr. 29010; New York Botanical Garden. 



The small flowers of C. microflora enable it to be easily distinguished from its 

 nearest relatives, C. bauhinae folia Benth. and C. parvifolia Tul. The inflores- 

 cence is very similar to that of C. bauhinae folia but the leaflets as well as the 

 flowers are much smaller. The leaflets of C. parvifolia are nearer the size of 

 those of the new species but they are smaller yet and oblong." The very minutely 

 puberulent, later glabrate, branchlets of the new species contrast with the per- 

 sistent, more obvious pubescence of the relatives. 



Macrolobium Schreb. 



Several collections of this genus were made and they are cited under the 

 names now in use. However, a monograph of the genus is in progress at the mo-
