294 NOTES ON THE GENERA 
took the opportunity of illustrating one of them, Harpalyce, by means 
of a species not uncommon in the Brazilian mining districts, my conclu- 
sions having been since confirmed by specimens of the Mexican species 
brought home by the late Dr. Coulter; and I now feel persuaded that 
I have identified another of them, Lecostemon, in four or perhaps five 
Brazilian and Cayenne species, all as yet unpublished, though one at 
least has been for near half a century in our herbaria. The Mexican 
type is however in this case still unknown to me. 
Lecostemon was placed by De Candolle at the end of Rosacea, as a 
very doubtful associate, but, making allowance for some inaccuracies, 
easily accounted for in describing from a drawing, the most important 
discrepancies vanish, and the remaining characters not only leave no 
room for hesitation as to the identification of the genus, but place it 
most clearly among Chrysobalanacee, though as a very distinct genus, 
of which the following may be considered as an extended character :— 
Calyx brevis, late cupulatus, dentibus 5 brevibus latis v. obsoletis. 
Petala 5, ad marginem disci calyeem intus fere totum vestientis in- 
serta, estivatione imbricata, quinto intimo. Stamina numerosa, 
disco inordinate inserta ; filamenta brevissima, persistentia ; anthera 
longe lineares, erectæ, basifixee, caduce. Ovarium sessile, globo- 
sum, glabrum, uniloculare. Ovula 2, erecta, inserta placente mem- 
branacex interdum fere in dissepimentum spurium expanse, Stylus 
e basi ovarii adscendens, simplex, filiformis, acutus, hinc a basi v- 
a medio stigmatosus. Drupa parva, globosa, putamine crustaceo. 
Semen abortu unicum, reniformi-globosum, exalbuminosum, testa 
tenui, cotyledonibus crasso-carnosis fere conferruminatis, radicula 
parva inflexa ad hilum spectante.—Frutices Austro-Americani. Folia 
alterna, coriacea, integerrima. Stipule parve, subulate, v. obsolete. 
Pedunculi in axillis superioribus racemosi v. subpaniculati. Bractee 
et bracteole squameformes. Pedicelli sub calyce incrassati, sæpe cer- 
nui, fructiferi cum calyce plus minus incrassato-carnosi. _Filamenta 
post anthesin diu persistentia, supra calycis disciformis marginem 
subrecurva, fere glanduliformia. Anthere uti petala caducissima. 
From the above character that given by De Candolle differs chiefly 
in that he states the flowers to be apetalous ; but a glance at the speci- 
mens will readily suggest that in a not very accurate drawing the 
petals might look like coloured petaloid deciduous lobes of the calyx. 
The ovary is also said to be “in stylum desinens,” but this again is a
