 leafy below, and with manifest short branches: leaf-divisions linear, a 

 line broad: achenes somewhat obovate, smooth and naked on the back,

 heads: leaves tripinnately divided into filiform segments: achenes oblong 

 or obovoid, obscurely 3 — 5-nerved, narrowly callous-winged; pappus a 

 slight coroniform cup. -Remarkable tree-like plant of almost palm-like

 was recently discovered on the mainland at Point Sal, Santa Barbara 

 Co., by Mrs. Blochman.
