habit is the same, and the leaves very similar in shape. It 

 also has the same long slender spikes extending beyond the 

 leaves. The main stem likewise is glabrous, but the branches 

 are hirsute. There is a difference also in the veining, for in- 

 stead of the "five conspicuous basal or sub-basal nerves," there 

 are but three veins, with faint indications of a fourth and fifth 

 on some leaves. The under side of the leaves instead of being 

 glabrous, are hirsute, and the upper side bears a line of hairs 

 on the midrib. It may be Hillebrand's P. hypoleuca var. kauai- 

 ensis, which he says is "intermediate between the present 

 species (hypoleuca) and P. membranacea," but he describes the 

 plant as having " oblanceolate or oblong " leaves. The leaves 

 of my plant are ovate. Collected in damp woods at an eleva- 

 tion of 3000 feet.

 Three numbers were collected which seem referable to this 

 species. The first (2077), was collected on the heights of Pa- 

 uoa, Oahu, where it was growing in the forks of Kukui trees. 

 The plants are small and grow in tangled clumps. A second 

 number (2534), is very similar but smaller, and has somewhat 

 thicker spikes. It also grew on Kukui trees, along the Wahi- 

 awa and Hanapepe rivers, Kauai. The third number (2481), is 

 much larger in every way. It was found growing only on the 

 ground, first along a tributary of the Hanapepe river, Kauai, 

 and later in the woods at 4000 feet elevation above Waimea. 



Peperomia 



About a mile above the mouth of the main tributary of the 

 Hanapepe river, Kauai, was collected a plant which does not 

 seem to agree with any of the Hawaiian species, although it 

 seems to be close to P. sandwicensis. The plants were growing 

 in wet, muddy ground, at the base of a ledge of rock. They 

 are small, none being over six inches long, including the long 

 spikes. The stems are short, branching from near the decum- 

 bent base, somewhat channeled, smooth below, the upper part 

 and the branches, pubescent with short hairs that curve up- 

 ward. The leaves are in whorls of three, or sometimes the 

 lower ones opposite, on hairy petioles of about one-fourth their 

 length. Including the petiole, the largest are about an inch 

 long, obovate, or almost orbicular in outline, thick, three-
