This species, of which I have at hand only fruiting specimens, is very closely 
related to Clidemia dispar (O. Berg) Cogn. of the Section Calophysoides, 
collected in eastern Peru by Spruce. It differs in the compressed, glabrous 
branchlets, the much larger leaves with entire margin and with appressed- 
pubescent, not stellate, nerves, and finally in the long, slender and few- 
flowered inflorescences. According to the notes taken on the spot when 
collecting the plant, the flowers are small and white. It is likely that some 
will be found on the specimens elsewhere distributed. 
CLIDEMIA GRANDIFOLIA Cogn. in DC. Monogr. Phan. 7: 1018. 1891. 
My no. 8917 coincides with the description of this species as to the charac- 
ters of the branchlets, leaves and inflorescence, but it differs slightly as to 
those of the flowers. It seems likely, however, that the plant is specifically 
identical with the one described by Cogniaux. 
I have noted the following complementary data: 
Frutex 2-3 m. altus, erectus, paucirameus, ramis robustis. Petioli crassi, 
5-10 em. longi; laminae 15-25 cm. longae, 14-21 em. latae, supra sparsissime 
breviterque setulosae, subtus ad nervos sparse furfuraceae, demum glandulis 
minimis translucidis adspersae. Paniculae in axillis fasciculatae, laxae, 
subnutantes. Pedicelli 5-6 mm. longi. Calyx tubuloso-urceolatus, 3.54 
mm. longus, basi 4-bracteolatus, dentibus interioribus nullis, exterioribus 0.5 
mm. longis, obtusis; bracteolae ovatae, obtusae vel acuminatae, circa 1.5 mm. 
longae. Petala alba, oblonga, obtusa, 2—2.2 mm. longa, 1.2-1.3 mm. lata. 
Filamenta 1.7 mm. longa; antherae 2.5 mm. longae, oblongae, basi apiceque 
acuminatae. Stylus 6 mm. longus, basi setosus. 
Type collected between Maracay and Choroni, Venezuela, 1300 m., (Fendler 
2263). Our samples were collected on the hills of Guaremales, 450 m., near 
Urama, Carabobo, fl. July 2, 1920, Pzttier 8917.
