only surpassed in beauty by the species of Stenogyne, which flower in the late 

 winter months. Their large curved corollas, which are borne in large whorls, 

 vary in shades from deep magenta to crimson, pink, yellow and pure white, in- 

 terlacing trees or gracefully festooning branches, or, as is often the case, 

 forming dense carpets covering the ground in small spots to the exclusion of 

 other plants. The handsomest species are St. Kamehamehae and St. longiflora. 



Another very important feature of the vegetation is the tribe Lobelioideae, 

 of which most of the species found here are new to science ; they belong nearly 

 all to the Sect. III., Palmaeformes, and are more or less closely related. The 

 most interesting is Cyanea aculeatiflora, which, as the name implies, is covered 

 with spines even to the lobes of the corolla; another peculiar new species is 

 Cyanea hamatiflora with broad sessile leaves, dark-red flowers, and large purple 

 fruits ; the latter plant is most common on Puukakai, where it reaches a height of 

 15 to 20 feet, similar to C. aculeatiflora. C. macrostegia with lobed leaves is not 

 uncommon, and so is C. atra, but differing from the specimens found on West 

 Maui. Cyanea ferox is here a shrub 15 feet in height with straight ascending 

 branches, which together with the stem are covered with thorns; the leaves of 

 this latter species are sinuate and remind one somewhat of Cyanea Grimesiana. 



Besides these tall species, two subherbaceous ones are found in the dense 

 shady moss forest, the taller one of the two, Cyanea BisJiopii (a new species, but 

 first collected by the late E. Bishop, and referred by Hillebrand doubtfully to 

 Cyanea Kunthianaf), with purple flowers, is the most common, but flowers, un- 

 like the other species, in the winter months. As we cross Waikamoi, where we 

 meet again with Ounnera petaloidea and Hillebrandia sandwicensis, the Ha- 

 waiian begonia, the forest becomes more uniform. At the edge of Waikamoi 

 proper, we find Lobelia macrostachys and a species of Wikstroemia, probably a 

 new species. The writer crossed this forest belt from Olinda to Honomanu and 

 followed along the ditch trail to Kailua. A forest as described in the above pages 

 covers this stretch of land, and it may be remarked that at about 3000 feet ele- 

 vation, above Honomanu, there are two clumps of Palms, Pritchardia arecina 

 Becc. This palm, discovered by the writer, is new to science, and is described by 

 Beccari in Webbia Vol. IV. Lower down along the ditch trail proper the forest 

 has died for miles, the cause being still unascertained. All the Ohia trees are 

 dead, and only here and there a species of Tetraplasandra is struggling for exist- 

 ence. Since the death of the tree growth the lobeliaceous Clermontia macro- 

 carpa, so common on Oahu, has become almost the sole underbrush, with here 

 and there a species of CI. arborescens. 



What has been said of this forest belt up to Honomanu holds good for 

 Keanae and Nahiku, the only exception being the presence of Sideroxylon rhyn- 

 chospermum at Nahiku, besides several species of Cyanea. 



The forests spoken of by Hillebrand at Ulupalakua have entirely disappeared 

 and only remnants of them can be found. Cheirodendron Gaudichaudii is still 

 common, besides Suttonia, and Ohia lehua; numerous still is the araliaceous
