Order XVII. TAMARISCINE^. 



A small Old World order of trees and .shrubs, mainly represented by the 

 Tamarisks {Tamarix), and distinguished from all related orders with free ovary and 

 separate styles by its comose or long-hairy anatropous seeds. To it has lately been 

 referred, by Benthani k Ilookor, Gen. PI. i. IGl, the following anomalous (chiefly 

 Mexican) genua.

Sepals 5, free. Petals united into a tube ; tlie 5 lobes of the limb imbricated, 



spreading. Stamens 10 to 15, hypogynous, exserted ; filaments thickened at base. 



Ovary imperfectly 3-colIed ; plaoontaj about 6-ovuled : styles 3, long, somewhat 



united. Seeds 3 to 6, oblong, flattened, surrounded by a dense fringe of long white 



hairs or by a membranous wing. — Shrubs or small trees, witli soft fragile wood, 



smooth ; the branches alternately spinose-tubercled, and with single or fascicled 



thick entire leaves in the axils ; flowers brilliant crimson, in terminal spikes or 



panicles. 



A Mexican genus of three species, only ono of which passes northward into the United State.s. 

 Its characters are anomalous, and it has l)een placed by difTeront authorities in the ordei3
