exposed than the one in Pauoa, where 2010 was collected, 

 being just on the edge of the forest, and in rich, damp soil. 

 The stems in these specimens are somewhat hirsute, especially 

 on young shoots, where the leaves are in whorls of three or 

 more. It is of erect growth, about eight inches high. The 

 leaves, branches, and flowering spikes disarticulate readily in 

 all three numbers. 



Peperomia macraeana'O. DC. Seem. Journ. Bot. 4:145. 1866. 

 Some of the specimens under No. 2338 undoubtedly belong 

 to this species. They were collected at an elevation of about 

 1500 feet, in wet woods at the head of Kalihi valley, Oahu. 

 The species is perhaps rather common in damp woods. 



Peperomia macraeana C. DC. var. 



These specimens were collected in wet woods, at an elevation 

 of 3000 feet and more on Kauai, principally on the ridge west 

 of the Hanapepe river. They seem to resemble P. membranacea 

 somewhat, but the character of spikes shorter than the leaves, 

 forbids that disposition of them. 



July and August (2612). 



Peperomia macraeana nervosa Hillebr. Fl. Haw. Is. 421. 



1888. 



Above Waimea, Kauai, where Hillebrand's type was collected 

 and near the head of the Wahiawa, were collected specimens 

 which answer to the description of this plant, except the clause 

 "purplish underneath, excepting the course of the nerves." 

 They are whitish underneath in my specimens. The plant is 

 light green instead of dark green as in the species, and has 

 thicker leaves and spikes. It appears to be quite distinct. 



Peperomia membranacea H. & A. Bot. Beechy, 96. 1832. 



Part of No. 2238, collected at the head of Kalihi valley, 

 Oahu, belongs to this species. It seems to grow only in dense 

 wet woods. The slender spikes, extending much beyond the 

 leaves, the broader and thinner leaves, and the arrangement 

 of the veining of the leaves, distinguish it from P. macraeana, 

 specimens of which were collected at the same place, and in- 

 cluded under number 2338. Collected May 20th. 



Peperomia membranacea H. & A. var. 



On the ridge west of the Hanapepe river, Kauai, plants were 

 collected which seem to be referable to P. membranacea. The
