C. Menziesii var. y Gray in Proc. Am. Acad. IV. (1860) 49; — Wawra in Flora 

 (1874) 326. 



A small tree 5 to 6 m in height, with stiff, stout ascending branches, densely foliose, 

 covered with stipules below and more or less pubescent; leaves obovate or spathulate, 

 18 to 25 mm long, 10 to 12 mm wide, penninerved, bluntly acuminate or rounded, the base 

 contracting into a margined petiole, thick coriaceous, shining; stipules broad triangular, 

 ciliate at the upper border; ilowers axillary, sessile on very short and thick spurs; female 

 flowers: calyx 2 mm, urceolate, the limb denticulate; corolla 4 mm, deeply 5 to 6 parted, 

 with reflexed lobes; styles 6 mm; drupe yellow or reddish, ovoid, 6 to 8 mm, tipped with the 

 short ealycine limb. 



This species, which is occasionally a shrub of 3 to 4 feet and often even pros- 

 trate as recorded by Hillebrand, is also a small tree 15 to 18 feet in height, 

 especially on Mauna Kea, Hawaii, at an elevation of 10000 feet, above the 

 crater of Kaluamakani and on Papalekoki as well as Moano and Nau, where it 

 grows in company with arborescent compositae such as Baillardia struthioloides, 

 B. arborea, as well as with the leguminous tree, Sophora chrysophylla, the 

 Mamani of the natives. It is decidedly a high mountain species, as it grows to a 

 small tree on Mt. Haleakala on Maui, on the crater of Puunianiau in company 

 with Mam.ani and Santalum Haleakalae, a species of sandalwood peculiar to that 

 mountain. On Mt. Hualalai, Hawaii, 8000 feet, it is a shrub 4 feet high and 

 grows with Dodonaea viscosa. The leaves are thick glabrous but almost succulent 

 in all locations. 



Two varieties /8 and y occur in the high mountain swamps of Puukukui, "West 

 Maui, and Waialeale, Kauai, respectively. The varieties are prostrate, but occa- 

 sionally shrubby.
