Hillebrand's speeinieii, in the Gray Ilerbariuin, from the Waianae ilouutains, 

 OahU; is quite fragmentary and is labeled ''Lobelia iicriifolia var. yuccaeformis 

 same as comm. by V. Knudsen. " Hillebrand himself was not quite sure if his 

 plant was not, after all. referable to Gray's L. ncriifolia; since the Oahu speci- 

 men consists of the upper portion of a raceme only, it cannot be determined 

 whether it belongs to L. neriifolia or L. yuccoides.

(Plate 67.) 

 Stem frutieuse stout, the medula solid; leaves crowded, elongate-linear, nar- 

 novving at Ijoth ends, attenuating into a marginate petiole about 5 mm long, 

 coriaceous, transversely veined, margin entire revolute, glabrous above, whitish 

 below, 10-20 em long, 5-14 mm wide, raceme virgate, densely tlowered, 15-40 cm 

 long; bracts and calycine lobes subulate-setaceous, the former 3,5-4 cm long, the 

 latter about 10 mm long, calyx tube whitish, turbinate; corolla blue, suberect, 

 puberulous; stamiual column pubescent; anthers glabrous, only the lower peni- 

 cillate: capsule dehiscent through the short and obtusely conical vertex.

Hillebrand absolutely ignored the original description of A. Gray's Lobelia 

 neriifolia and drew up a description from an entirely difi'erent plant; his descrip- 

 tion is exactly the opposite of that given by A. Gray. The original specimen 

 was collected on East Maui evidently on Haleakala, where the writer collected 

 his material. The species is rather abundant at an elevation of from 5000-7000 

 feet on the northwestern .slope of the crater as well as in both the Koolau and 

 Kaupo gaps in the crater. The species resembles somewhat Lobelia hypolenea 

 but differs from it in the short and narrow leaves with revolute margins, the 

 densely flowered raceme, and ovate, obtuse capsule. The racemes are usually 

 single; oidy occasionally two or three small ones appear at the base of the main 

 raceme (no. 8640). The Kauai plant no. 5959 is here referred to this species on 

 account of the ovoid obtuse capsule and the leaves, which are like those of 

 Lobelia neriifolia from Haleakala; the plant does not exactly agree with the 

 typical species, though comes much closer to it than to Lobelia hypoleuca. The 

 latter does, however, occur on Kauai, where it reaches a height of six feet or 

 more. 



The type of Lohdia m rii folia A. Gray in the Gray Herbarium is exceedingly 

 fragmentary, consisting of three single leaves and a few very old capsules; the 

 leaves are about 31 cm long and 8-10 mm wide, and belong unquestionably to 

 plants found on Mt. Haleakala on ilaui. The question arises if Lobelia neriifolia 

 is not identical with Hillebrand's Lobelia yuccoieles. The fragmentary type of
