Said to be shrubby. The leaves are thick, opposite, on slen- 

 der petioles of- about one-fourth the length of the blade, serice- 

 ous on both sides, especially so beneath, ovate or elliptical- 

 ovate, acute or acuminate; inflorescence corymbose, trichotom- 

 ous; pedicels slender, as long, or the ultimate ones sometimes 

 twice the length of the spikes. The type is Remy's plant, No. 

 207. Under this number are two forms, one from Hawaii, with 

 acuminate leaves on slender marginless petioles, the other 

 from Oahu, with bluntish leaves, on margined petioles. On the 

 ridge leading up to Kaholuamano, Kauai, between the forks of 

 the Waimea river, I collected two forms, referable to Remy's 

 plant. One, an erect, compact bush, three to four feet high, with 

 thick, elliptical, mostly obtuse leaves, grew on the open, ex- 

 posed slope, at an elevation of about 2500 feet. The other grew 

 in the shade, on the banks of a stream in a canon, at about 2000 

 feet elevation It is a larger bush, with more spreading 

 branches, the leaves somewhat thinner, elliptical-lanceolate in 

 shape, acute In both of these forms the leaves are on short 

 margined petioles.

There is not the least doubt about Mann & Brigham's No. 

 590 being specifically distinct from Remy's No. 207. The 

 former I have seen in the Herbarium of the Bernice Pauahi 

 Bishop Museum, at Honolulu, and the latter in the herbarium 

 of Columbia University. In the publication of Ptilotus sand- 

 wicensis, the numbers are cited thus: " (M. & B. 590; Remy, 

 207)." In Hanapepe valley, Kauai, the type locality for M. & 

 B. 590, it is not uncommon at elevations of 300 to 600 feet, usu- 

 ally growing on steep slopes. It is a small tree about ten feet 

 high, with spreading branches. On the living plants, the foli- 

 age has a rufous tinge. The leaves are thin, elliptical ovate, 

 acute or acuminate, tapering below into a margined petiole, 

 glabrous above, shortly pubescent beneath, especially the
