314 PHANEROGAMIA. 



mens of our glabrous variety are smaller in all their parts, and were 

 apparently gathered at a greater elevation ; they have short and few- 

 flowered peduncles, and are wholly in fruit. The form of var. hypo- 

 leucum from Kauai apparently came from a great elevation : the 

 plants are only a span high, naked, as if they had grown in moss; the 

 branches tipped with a cluster of small leaves, and destitute of flower 

 and fruit. The var. hololeucum usually exhibits the largest leaves and 

 a fuller cyme of flowers.

Shrub apparently of 2 or 3 or several feet in height, with spreading 

 branches, which are thickly scarred, or the branchlets clothed with 

 the conspicuous, connate, subulate-pointed, scaly, persistent stipules, 

 which are like those of the two preceding species. Leaves ehartaceous, 

 or nearly membranaceous, or in a stunted form coriaceous, ovate, more 

 or less acute, rather finely but sharply serrate with appressed mucro- 

 nate teeth, except towards the obtuse or rounded base, which is entire, 

 from one to 21 inches long, T-ll-newed ; the nerves sparingly forked 

 or branched and inosculating ; the upper surface glabrate and green, 

 or rarely canescent when young ; the lotver more or less whitened 

 with a fine silky or silvery pubescence. Petioles slender, pubescent, 

 from half an inch to W inches in length. Peduncles opposite the 

 leaves, or terminal, an inch or so in length, usually forked, few- 

 (3-7-) flowered, or by abortion one-flowered; the peduncle or its
