78 CELASTEINE^. 



2. E. trilobata, Nutt. in T. & G. Fl. i. 219 (1838). Diffusely branching, 

 2 — 5 ft. high, aromatic-scented, more or less pubescent when young : 

 terminal leaflet thrice as large as the lateral, cuneate-obovate, 1 — 2 in. 

 long, 3-lobed and coarsely toothed above the middle ; lateral pair round- 

 obovate, scarcely lobed, but coarsely crenate : spikes 3^ — ^^ in. long, 

 short-pedicelled i fr. viscidly hirsute, the thin pulp keenly and pleasantly 

 acid. — At middle elevations of the mountains, but not very common. 

 The very tough and flexible branches were employed by the Indian 

 women in their finest basket-work, and southeastward the shrub is 

 locally known as Squaw Bush. Tlie species is clearly enough distinct 

 from the Atlantic E. Canadensis, in which the leaflets are of about equal 

 size, alike in form, and none lobed. These shrubs are scarcely congeneric 

 with Poison Oak ; and probably both Toxicodendron and Lohadium are 

 defensible as distinct from Rhus.

 axillary cymes. Sepals and petals 4 or 5, widely spreading. Stamens 

 very short, on a broad angled disk. Ovai-y immersed in the disk, 3 — 5- 

 celled ; style short or 0. Capsule coriaceous, 3 — 5-lobed and -valved. 

 Seeds 1—4 in each cell, covered with a fleshy red aril. 



1. E. occidentalis, Nutt. in Torr. Pac. E. Eep. iv. 74 (1857). Erect,
