DIAGRAMS OF EXOCARPUS LUTEOLUS FORBES, 



I. Fruit. 2. stamen. 3. Flower. All variously enlarged. 



A shrub two to six feet high. Leaves cuueate to oblong- 

 lanceolate, inclined to be concave, thick coriaceous, subsessile, 

 yellowish-green, veins rather indistinct, 12-24X7-9 liwes. 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 re.spects this species seems to be intermediate be- 

 tween E. Gaudichaudii, A. DC, and E. 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
