post carnem drupz destructam persistentes, fructum siccum 5-costa- 
tum simulant. ; 
In shady campos or savannahs, British Guiana, Rob. Schomburgk, 
Ist coll. n. 179, 2nd coll. n. 1001, Rich. Schomburgk, n. 1737; near 
Barra, on the Rio Negro, R. Spruce. I have also seen it in collections 
from Surinam, and I believe from French Guiana. The flowers are 
white (more or less spotted with red, according to Schomburgk), scented 
like those of Gymnadenia conopsea. Stamens white, but red at their 
insertion. Fruit of a deep brown-red. 
3. C. discolor, Spruce; stipulis brevissimis, foliis ovalibus ramisque 
glabris, corollæ sericeo-pubescentis tubo calycem glabrum tubulosum 
5-dentatum vix duplo excedente.—Folia circa 3 poll. longa, 13-2 
poll. lata, coriacea, penninervia et reticulato-venosa, supra nitidula, 
subtus pallida. Spice pedunculatz, foliis longiores. Flores sepius 
oppositi. Calyx glaberrimus, 4—44 lin. longus, dentibus brevibus. 
Corolle tubus 7-8 lin. longus; limbi lacinize lineares v. subspathulate, 
fere 6 lin. longe. Anthere acutissime sed vix aristate, appendi- 
cula baseos integra. 
On the Rio Negro, in the inundated campos opposite Uananaca, 
R. Spruce. It is a shrub of 7 feet, with handsome flowers of a full red. 
Leaves, when fresh, of a glaucous-white underneath, which goes off 
much in drying. 
4. C. speciosus, Spruce; stipulis abbreviatis, foliis oblongis ramisque 
glabris, corollz sericeo-villosee tubo calycem asperulum minute den- 
tatum subtriplo superante.—Stipule in cupulam brevissimam trun- 
catam connate. Folia 6-9 poll. longa, 23 poll. lata, obtuse acumi- 
nata, basi cuneata, coriacea, costa subtus valde prominente, venis 
subparallelis crebris, venulis reticulatis. Spice plereeque foliis bre- 
viores, floribus sparsis. Calyx vix 3 lineas excedens, dentibus mi- 
nutis. Corolle tubus 8 lin. v. fere 9 lin. longus, limbi laciniæ 5 lin. 
Anthere brevissime aristate, appendice baseos integra. Pyrene 
compresse, obscure angulatze. Semina oblonga, incurva, ventre 
affixa, albumine parca. 
Gathered by Mr. Spruce near San Gabriel, where it formed a shrub 
of about 8 feet in height, fringing a small sandy campo scarcely 100 
feet by 10 in the midst of the forest, bearing a profusion of red 
flowers down to the very ground, and having at a little distance the 
aspect of a Rhododendron.
