552 cxxii. EUPHORBiACE^ (brown). [Ei(phorhia. 



Leaves alternate; petiole 2-4 lin. long; blade 6-8 lin. long, 8-0^ lin. 

 broad, or perhaps larger, elliptic-oblong, obtuse, cuneately rounded into 

 the petiole, longitudinally folded in the specimens seen, somewhat fleshy. 

 Stipules none. Bracts under the involucres sessile, J-J in. long and as 

 broad or broader than long, orbicular-rhomboid or transversely rhomboid, 

 very obtuse, longitudinally concave-folded so that the pairs form a sort 

 of cup. Involucre solitary, terminal, sessile, about 1| lin. long and 1 J 

 lin. in diam., subcylindric-obconic, glabrous outside, with 5 glands and 

 5 oblong minutely 3-toothed pubescent and ciliate lobes ; glands ^-| 

 lin. in their greater diam., transverse, somewhat elliptic-oblong and 

 2-lipped, with the small rounded entire inner margin inflexed and the 

 much larger jounded minutely crenate outer margin spreading. Ovary, 

 capsule and seeds not seen, all the involucres examined being njale.

96. E. incurva, N. E. Br. Stem in the only specimen seen (a piece 

 9 Jin. long) apparently succulent or herbaceous, but possibly a branch 

 from a shrub, about 2 lin. thick, tapering upwards, branching, glabrous. 

 Branches alternate, numerous, subequidistant, 3-5 lin. apart, 1 h-\ in. 

 long, 1 lin. thick, horizontally spreading at their basal part, then up- 

 curved, leafy at the tips, naked and marked with prominent leaf-scars 

 below, glabrous. Leaves alternate, i-| in. long, 1-1^ lin. broad, linear- 

 lanceolate, with inrolled margins, acute, somewhat rounded or tapering 

 into a petiole 1-1 J lin. long, glabrous above, puberulous with minute 

 curved white hairs beneath. Peduncles axillary, solitary, -|-1 lin. lung, 

 bearing a pair of bracts and 1 involucre, glabrous. Bracts l|-li lin. 

 long, ^~§ lin. broad, somewhat rhomboid-elliptic, acute, with incurved 

 margins, puberulous on both sides. Involucre sessile between the 

 bracts, about 1 lin. in diam., cup-shaped, puberulous, with 4 ghinds 

 and 5 quadrate puberulous densely ciliate lobes ; glands not contiguous, 

 \-\ lin. in their greater diam., transversely oblong or subquadrate, 

 entire, white-puberulous on the back and more or less on the upper or 

 inner surface, densely ciliate. Ovary exserted and curved to one side, 

 densely covered with minute curved white hairs; styles \ lin. long, 

 free, erect, bifid at the apex, puberulous.
