DIAGRAMS OF EXOCARPUS LUTEOLUS FORBES. 
1. Fruit. 2. Stamen. 3. Flower. All variously enlarged. 
A shrub two to six feet high. Leaves cuneate to oblong- 
lanceolate, inclined to be concave, thick coriaceous, subsessile, 
yellowish-green, veins rather indistinct, 12-24 7-9 lines. Spikes 
1.5 inches long, four- to nine-flowered with many empty bracts 
below. Perianth very small, greenish, five- to six-parted; its 
lobes acute, one-half of a line long. Nut cylindrical, nearly five 
lines long, pointed at the apex with four indentations. 
In many respects this species seems to be intermediate be- 
tween &. Gaudichaudii, A. DC., and &. brachystachys, Hillebr. 
It differs in its much longer spikes, and in having only expanded 
leaves, these being stiffer, of a more yellowish green, usually 
smaller and of a different shape than those of £. brachystachys 
(72) [296]
