190 PHANEROGAMIA. 



Oneata, Feejee Islands. Hawaii and Oahu, Sandwich Islands, on the 

 coast. 



All the specimens from the South Sea Islands, having sessile heads, 

 belong to the Waltheria Indica of Linnaeus, which has been justly 

 united to W. Americana. Those from Rio and the Sandwich Islands 

 have the heads either pedunculate or sessile. In this, as in the fol- 

 lowing species (vid. Cav. Diss, infra cit. f. x.), some flowers have the 

 androecium less developed than others, their shorter filaments being 

 monadelphous nearly to the top, while in others they are united only 

 at the base.

Waltheria ovata, Cav. Diss. 6, p. 317, t. 171, f. 1; DC. Prodr. 1, p. 493. 



Hab. Yaso, Caball, and below Obrajillo, Peru. 



Well distinguished by the fine and close velvety tomentum, the 

 broadly ovate leaves, and the pointless calyx-lobes, which are entirely 

 destitute of hirsute hairs. — Nearly related to this is Dr. Hooker's IT.

3. Waltheria pyrol^folia, Sp. Nov. 



W.fruiicosa; foliis confertis coriaceis rotundis scepius utrinque retusis 

 serrulatis plicato-venosis supra glabris subtus canescentibus glabratis; 

 glomerulis axillaribus subsessilibus plurifloris ; calycis cano-sericei 

 lobis lanceolatis obtusis petalis glaberrimis brevioribus. 



Hab. Sand-hills near Wailuku, Maui, Sandwich Islands. 



Stems from a foot to 3 feet high, erect, shrubby to the top, much 

 branched; the branches, petioles, &c, canescently villous-tomentose, 

 rigid. Leaves crowded on the branches, coriaceous, roundish, inclining 

 to orbicular-obovate, commonly more or less refuse both at the base 

 and apex, about an inch in length and breadth (the smaller 8 or 9
