THE PLANTS OF THE PRIBI^OF ISLANDS. 573 



with 0. limula, Fries, but the leaves are narrower and the shqrtpeduncled spikes 

 erect. 



144. Care:s salina, Wahl. 



This species, in one or other of its many forms, is common on both islands. The 

 commonest of these is 0. salina, subsp. cuspidata, Wahl., var. haematolepis, Drej., 

 which grows everywhere on grassy uplands. The form thulensis. Th. Fries (Herb. 

 ]^o. 1 6618), was collected in a slightly saline marsh. With it grew the var. subspa- 

 thacea, Wormskj. (Herb. No. 16619). The varietal determinations given above were 

 made by Mr. Kukenthal. 



The Garex rigida Mgelovii of Dr. Merriam's list I believe to be this species, though 

 I have not seen his specimens. 



145. Carez oryptooarpa, C. A. Meyer. 

 Common on both islands. 



146. Carez maoroohaeta, C. A. Meyer. 



C. podocarpa, E. Br. 



Common on both islands; the form graeilior found in one locality only. 



147. Carez maoroohaeta, C. A. Meyer, var. subrigida, Geo. Kukenthal. 



Low, culm and leaves rather broad and very rigid, the leaves longer than the 

 culm; the lowest spike female at the base; all the spikes longer and much narrower 

 than in the type, club-shaped, rather loose flowered toward the base; scales hardly 

 or npt at all aristate. Herb. No. 16615. 



Perhaps a hybrid between G. macrochaeta and G. haematolepis, though as these 

 species belong to two different sections and there is little evidence of hybridization 

 apart from the general appearance of the plant^ I prefer to adopt the name given it 

 by Mr. Kukenthal. 



148. Carez membranopacta, Bailey, Bull. Torr. Bot. Club, Vol. XX, p. 428, 1893. 



Very abundant in a large depression around a pond on St. Paul Island. This 

 carex, at least where found by me, grows in clumps and is decumbent in habit, cover- 

 ing an area of from 24 to 30 inches in diameter. Dried specimens give no hint that 

 the plant is not erect in habit; but the fact is that on St. Paul Island, at least, it lies 

 flat on the ground, even when very young. At maturity the whole plant is frequently 

 covered by the surrounding herbage. Herb. No. 16608, distributed as G. compacta, 

 E. Br. The G. saxatilis of Dr. Merriam's list I take to be this species. 



149. Carez rariflora, Smith. 



Collected by Mr. Palmer on St. Paul. Island. 



150. Hierocbloa borealis, E. and S. 

 Not rare on either island. 



151. Hierochloa pauciflora, E. Br.' 

 Eare on St. Paul Island. 



152. Alopecunis alpiuus, Smith. 

 Common on both islands. 



153. Alopecurus howellii, Vasey, var. merriami, Beal. 



On bare ground that has been used as hauling grounds by seals. Grows in dense 

 clumps; decumbent in habit. Not seeii elsewhere than on dry, bare ground.
