EUPHORBIA (§ TITHYMALUS ?) ERYTHROXYLOIDES, n. sp. 
Fruticosa, glabra, ramulis gracilibus lignosis sub apicem crebre nodu- 
losis, foliis ad apices ramulorum fasciculatis petiolatis ovatis vel oblongis 
integris membranaceis cuspidatis, involucris ad apices ramorum umbellatis 
pedunculatis basi foliis 2 obovato-cuneatis stipatis, tubo campanulato, 
appendicibus 5 crassis erectis rotundatis plus latis quam longis. 
A tree, with slender terete flexuose divaricating woody ulti- 
mate branchlets, furnished towards the tip with copious crowded 
raised semilunar scars. Leaves solitary or in small whorls at the 
tip of the branchlets, on short slender petioles; blade 4-14 in. 
long, acute, deltoid at the base, thin in texture, green and glabrous 
on both surfaces, all the veins except the midrib indistinct. 
Tnvolucres 3-8, in whorls from the tips of the branchlets with the 
leaves, on erect peduncles 4-4 in. long ; tube campanulate, 1 lin. 
in VULT with 5 broad short rounded thick erect entire appen- 
dages and two opposite obovate-cuneate membranous glabrous 
bracts twice as long as itself. Flowers only seen in a young 
stage.— Wood near Analamazoatra, Meller! Central Madagascar, 
Baron 1223! Near Ampasimpotsy, Baron 1621! A very curious 
species, of which specimens in a later stage are required.

Arborea, glabra, foliis confertis brevissime petiolatis oblanceolato-oblongis 
obtusis subcoriaceis utrinque viridibus subtiliter venulosis, capitulis mas- 
eulis globosis pedunculatis bracteis 3-4 oblongis obtusis reflexis glabre 
suffultis, perianthio piloso dentibus deltoideis, filamentis quam anthere 
globose quadruplo longioribus. 
A tree, with crowded slender branchlets, glabrous in all its 
p. ee crowded, alternate, x gd, petiole not more 
than j-$ in. long; blade 1-13 in. long, 8-3 in. broad above the 
radia narrowed gradually from the middle to the base, firm in 
texture, green and minutely glanduloso-punctate on both sides, 
the fine distant arcuate ascending main veins anastomosing by 
arches within the margin. Female flowers and fruit not seen. 
Male flowers in a globose head 1 in. in diam., on a slender peduncle 
4-3 in. long, with 3-4 reflexing glabrous bracts i in. long at the 
base. Perianth infundibuliform, minutely toothed, shorter than 
the filaments. Stamens 3 in. long.— Central Madagascar, Baron
