244 PHANEROGAMOUS PLANTS. 



3. Arenaria laricifolia, Linn. 



Var. clespitosa: caulibus foliisque viscoso-puberulis ; sepalis acutiuscxdis, 

 nervo medio latissimo. 



Hab. Upper Columbia River, Washington Territory. — Perennial. 

 Stems somewhat woody below, throwing up numerous erect rigid 

 branches, which are about a span high, minutely and somewhat glan- 

 dularis pubescent. Lower leaves closely approximated, and appearing 

 fasciculate, erect; the uppermost distant, all of them narrowly subu- 

 late, rigid, and somewhat pungent, about an inch long. Cymes few- 

 flowered, rather contracted. Sepals ovate, with a broad thin margin : 

 the central part thick, nerveless, and resembling a broad midrib. 

 Petals obovate, nearly twice as long as the sepals. Capsule ovate, 

 very obtuse, a little shorter than the calyx ; the valves 2-cleft at the 

 summit. This is near the last species, but differs in the shorter and 

 pubescent leaves, compound cymes, and acutish sepals. From A. 

 laricifolia it differs in its longer leaves, much smaller and more 

 numerous flowers, broader nerveless sepals, &c. 



4. Arenaria Franklini, Dougl. in Hook. 



Hab. Banks of the Columbia, above the mouth of the Wallah- 

 Wallah, and on the Okanagan River. 



5. HONKENYA, Ehrh. 



1. HONKENYA PEPLOIDES, Ehrll. 



Hab. Shores of Puget Sound, and Straits of De Fuca; also at 

 Gray's Harbor, which is the most southern station known to us on 

 the Pacific coast for this plant. — The specimens of this collection show 

 a transition from H. oblongifolia to the ordinary form of R peploides, 

 and we now believe, with Ledebour, that there is but one species of 

 the genus.
