AND STERCULIACES. 109 
therefore propose their reunion with Bombas. Nor can we see 
any sufficient grounds for the adoption of Erione, Campylanthera, 
and Gossampinus, proposed by the same author for single species. 
of Eriodendron. 
SCLERONEMA, Benth. 
I give this name to a North-Brazilian plant of Mr. Spruce's, which 
on a hasty determination I had thought might be a new species 
of Myrodia, taken in the vague general limits usually given to the 
genus; but, having now more closely investigated the characters 
of that and other Bombaceous genera, I find that it is much more 
nearly connected with Hampea. The fruit is still unknown, but the 
flower presents too many points of difference to admit of its being 
incorporated with that or any allied genus. I therefore propose 
it as a new genus with the following technical character :— 
SCLERONEMA. Char. gen.—Calyx campanulatus, sub-5-lobus. 
Petala 5. Columna staminea brevis, apice divisa in fila- 
menta œ (circa 20) superne incrassata, exterioribus brevi- 
oribus. Anthere terminales, adnatæ, breves, uniloculares. 
Ovarium 2-3-loculare, ovulis in loculis geminis collateraliter 
ascendentibus. Stylus apice vix incrassatus, minute 2-3-den- 
tatus. Fructus......... 
Species unica, S. SPRucEANA, Benth.—Arbor 100-pedalis, trunco 
5 pedes diametro; corona patula. Stipule parve. Folia alterna, 
ovali-elliptica v. obovata, breviter et abrupte acuminata, 2-4-pollicaria, 
petiolo 4-1-pollicari, integerrima, coriacea, glaberrima, nitida, penni- 
nervia et basi subtrinervia, costa venisque utrinsecus primariis 6-8 
obliquis subtus prominulis; venule transverse, crebrz, reticulate. 
Flores haud magni, in axillis solitarii v. 2-3-ni. Pedicelli 3-4 lin. 
longi, crassiusculi, minute tomentelli. Bracteole sub calyce 2 v. 3, 
parvi, calyce multo breviores. Alabastra obovoidea. Calyx apertus 
3 lin. longus, fere ad medium sub-5-fidus. Petala duplo longiora, ru- 
bra, anguste oblonga, glabra, patentia, in unguem angustata. Tubus 
stamineus 2 lin. longus, filamenta, przesertim interiora, paullo longiora. 
Hab. In North Brazil, on the Rio Uaupés, in Caatingas about the 
cataracts of Jauaraté, where these tall trees project here and there 
from the mass of low trees and shrubs. R. Spruce, n. 2548. Distri- 
buted under the name of Myrodia parviflora. 
CARPODIPTERA, Griseb. 
This genus, established by Grisebach on a Cuban plant of 
Wright’s, and which I had at first, following that author, placed 
among Bombaces, proves on examination to differ from all others 
of the family as well in its stamens and its pendulous ovules as in
