This new genua differs from Astrma in tlie male flo-^ers growing singly from tlie axil of a bractea, and 
in the female flowers having deeply quadripartite styles and quite smooth seeds. From Oroton it is easily dis- 
tinguiahed by the absence of petals and by the more deeply parted styles in the female flowers. I only 
know seven species: Barhamia hispida (Croton hispidus, Kth.), B. macrostachya (Eichard Schomburgk, 
no. 382), B. JEssequiboensis (Croton Esscquiboensis, Kl.), B. urtic<rfolia (Croton urticEefolium, Zam.), 
C, multispicaius (Velloz. z. t. 75), B. omlifolia (Croton ovalifolium, Wlprs.), and B. Banamensis.

207. Barhamia PanamensiSj Kl. MSS. ; caule suffruticoso tcrcti erecto dicbotomo ramoso sparse 
stellatim applanato pHoso deinde glabro ; foliis longe petiolatis alternis ovatis acutis, sparse adpres- 
scque stellatim pilosis, cordatis insequaliter grosse serratis, dentibus ovatis obtusis mucronatis ; 
stipulis pedicelliformibus medio apiccque glanduliferis ; spicis in apice ramorum solitariis binis vel 
temis, pedunculatis, stellatim pubescentibus ; bractcis parvis ovatis inciso-glandulosis ; laciniis calycis 
fceminei ovato-lanceolatis uninerviis margine inciso-glandulosis. Near Nata, Province of Panama. 
A half-shrubby plant, a foot and more high. Leaves 2-3 inches long and 1-2 inches broad ,■ spikes from 
3-4 inches long. 
The species above characterized is very nearly related to Croton Idspidus, Kth. ; it difiera from that 
however in being less downy, the leaves being shorter-pointed, and the serrature very unequal ; the lobes 
of the female calyx are also much narrower than those of Croton hispidus.
