not have introduced it into his Icones, but for the gum it yields. His description of 
it differs from £rigona only in the branches being 5-angled; but the figure further 
differs in the more remote protuberance of the branches, in the much smaller in- 
volucres, in the few stamens, and in the involucral lobes though fimbriate not being 
further cleft into lobes; he further figures the ovary of trigona as furnished with 
a cleft calyculus, which is noteworthy. The number of stamens no doubt varies, for 
Wight observes that in Cattimandoo sometimes the outer involucres of the cyme are 
male, sometimes the inner, and that trigona occasionally produces branches with 
solitary male involucres, 
28. E. Royleana, Boiss. in DC. Prodr. xv. ii. 83; an erect glabrous 
fleshy shrub, branches with 5-7 broad flat faces and as many short thick 
obtuse undulate not lobulate wings with a pair of stipular thorns on their 
margins, leaves not described, involucres 3-4 in a contracted sessile 
cyme hemispheric, lobes cuneate fimbriate, styles free to the base P, cocci 
Compressed glabrous. Brand. For. Fl. 488; Gamble Man. Ind. Timb. 368.

, Attains 16 ft. in height and a girth of 6 ft. Branches in Royle’s figure 3 inches 
in diameter, with flat spaces between thewings. Jnvolucres j in. diam., yellow-green, 
emispheric. Capsules 3 in. diam.—Royle’s figure is unsatisfactory as to the styles. 
Brandis says it is probably the species of the dry hills near Jeypur which furnishes a 
great part of the fuel of that city. Boissier, who has never seen this, points out that 
the only character whereby Royle’s figure enables him to distinguish it from Wight's 
plato of Cattimandoo, which species also he has not seen, are the broad flat spaces between 
wings.
