Xeddera.] xc. convolvulace<e (baker and bundle). 75 



sparsely pubescent, like the leaves and bracts, with spreading forked 

 hairs, becoming spiny at the tip after flowering, leafless in fruit. 

 Leaves sessile, erect, up to 7 lin. long by 2 -J- lin. broad, elliptic-lanceolate, 

 mucronate, yellow-silky when young. Flowers axillary, sessile, solitary 

 or geminate; bracts leaf-like, about 2 lin. long and f lin. broad. 

 Sepals herbaceous, green, the 2 outer 3^ lin. long, produced from a 

 firmer ovate convex yellow-hirsute base, 1 lin. broad, into a long 

 foliaceous linear-subspathulate apex ; the 3 inner shorter. Corolla 

 white, about 4 lin. long, tawny-silky on the outside, except on the com- 

 missural segments, deeply 5-fid ; lobes subovate. Filaments with a 

 small crenulate stipule-like tooth on each side of the glabrous base. 

 Ovary densely hirsute ; style bifid nearly to the base with subequal 

 branches ; stigmas 2, minute, subrenif or m-peltate. Capsule very shortly 

 stalked, barely 3 lin. long, glabrous, 4-valvecl. Seeds 4, barely lh lin. 

 long, trigonous, glabrous, dirty-brown.

 with adpressed white hairs. Leaves distant, sessile, linear to narrowly 

 linear-lanceolate, ascending, margins sometimes convolute, |- 1 in. long, 

 thinly clothed with adpressed white hairs. Flowers arranged in sparse 

 racemes at the end of the branchlets ; pedicels short, bracteate at the 

 base by reduced leaves. Sepals rigid with herbaceous tip, obovate, 

 subacute, subequal, 1| lin. long. Corolla broadly funnel-shaped, 3 lin. 

 long, densely hairy on the midpetaline areas. Base of filaments triangu- 

 lar, not appendaged, glabrous ; styles free almost from the base ; stigmas 

 suborbicular. Ovary ovoid, hairy at the top. Capsule globose, 2 lin. in

 Broadly elliptic, rigidulous, shortly stalked, 2-4 lin. long, clothed with
