which can be found on nearly all the islands. Higher up, its place is taken by 

 the most interesting and peculiar as well as handsome forms, such as C. persicae- 

 folia, C. oblongifolia, C. drepanomorplia, etc. On Oahu the genus Rollandia, 

 also of the tribe Lobelioideae, is represented in the lower forest region by the 

 species R. lanceolata and E. grandifolia and another species of Rollandia found 

 to be new and named R. truncata by the author. 



Clermontia Kolialae, a strictly lower forest zone type, is also new to science. 

 It is found at Kohala on the island of Hawaii, where it is gregarious at 1500 

 to 2000 feet elevation, after which place it is named. It is a small, handsome 

 tree, flowering in the summer. To this region belongs also Cyanea angustifolia, 

 C. acuminata, C. grimesiana, C. scabra, all of which are peculiar to this region. 



The gesneriaceous genus Cyrtandra, with its many species, characterized 

 by the often bilabiate corolla, which is invariably white, having a fleshy berry 

 of the same color as the flower, with minute, almost microscopic seeds, belongs 

 to this zone; but not exclusively. These Cyrtandras have very few species in 

 this region, but reach their best development in the middle forest zone. 



The euphorbiaceous Claoxylon, a small shrub, may be found occasionally in 

 this zone, though most plentifully on West Maui in the valley of Waikapu. Of 

 vines, several Convolvulaceae, especially the genus Ipomoea, are found trailing 

 over guava, lantana and other introduced shrubbery which have established 

 themselves in the lower forest region. Besides the Convolvulaceae, Dioscorea 

 sativa and D. pentaphylla (Yam) are common, as well as the liliaceous Smilax 

 Sandwicensis (Ploi), trailing over trees. 



The Hawaiian Labiatae are conspicuous by their absence in this region, at 

 least in the region belonging to the windward subsection, though two are found 

 in the dry section. 



Of monocotyledonous plants, the following remain to be mentioned: The 

 Alocasia macrorrhiza (Ape), one of the huge species of taro, but not edible, 

 though in times of scarcity the stem was cooked and eaten by the natives. With 

 leaves several feet long, they can occasionally be found in shaded ravines or 

 valleys, besides the useful Tacca pinnatifida (Pia). The last, but not least, is 

 JIusa sapient um, the Banana, of which the natives recognized some forty odd 

 varieties, which is a typical feature of the lower forest zone, and with it is the 

 ginger, Zingiber zerumbet (Awapuhi). 



The cryptogamous flora is also represented in this region, its most conspicuous 

 and typical representative being the Asplenium nidus or bird's-nest fern, \vhich 

 usually is plentiful in the forks of the branches of the Kukui, with which it is 

 invariably growing when not terrestrial. Of other ferns, mention may be made 

 of the everpresent Xcphrolepis exaltata and the very troublesome Gleichenia 

 linear is (Ulithe), which covers the ground so thickly with its far-reaching branches 

 that it is next to impossible to penetrate any country taken up by this robust 

 fern. It is usually in layers of four to five or even more feet thick, the lower 

 ones usually dead, forming a canopy over which one crosses only with great diffi-
