tributaries, since Hillebrand records it from "Waimea, at ele- 

 vations of about 2000 feet." He attributes to it the erroneous 

 character of "branching shrub." It must be remembered that 

 Hillebrand personally knew nothing about the vegetation of 

 Kauai. He received all of his Kauai specimens from Mr. Vlad- 

 mir Knudsen, of Waimea, who owns a large tract of land west 

 of the Waimea river. The plant in question is simple, with a 

 trunk five to ten feet high, an inch or two in diameter, and 

 topped by a dense cluster of long, obovate- oblong leaves on 

 long petioles. The flowers are long peduncled, numerous in 

 the axils of the leaves. They are about an inch in length, al- 

 most white, or purple tinged, somewhat curved. It is figured 

 as Plate LXIV, which shows only a small portion of the top of 

 a plant

In making his key for this genus, Hillebrand appears to have 

 paid little attention to the original descriptions. To this spe- 

 cies he attributes "calcyine lobes nearly as long as the tube." 

 Mann's description is plainly contrary to this, for he says "lo- 

 bis calycis lanceolatis ovario multo brevioribus.." The chances 

 are that Hillebrand had an entirely different plant. At an ele- 

 vation of 4000 feet, on the plateau above Waimea, Kauai, I col- 

 lected specimens which Mr. Fernald has kindly compared with 

 Mann's type, and pronounced them identical. It is described 

 as ' 'a large branching shrub, 20 feet high, hirsute with short 

 rusty hairs." The leaves are "oblanceolatis utrinque acuminatis 

 crebre serrulatis, supra glabris petiolatis." My specimens are 

 frombrarching shrubs, eight to ten feet high, which grew only 

 on the banks of a forest stream. The leaves are four to six 

 inches long, on petioles of an inch or more in length. The 

 specimens are in fruit only.

The trunk of this species is usually about twenty feet high, 

 although much taller ones are sometimes found. It is three 

 inches or more in diameter, hollow, but here and there closed 

 by a white membrane, simple, and topped by a dense, round 

 crown of leaves, which are slightly drooping. The flowers are 

 crowded at the bases of the lower leaves, and from the remains
