Oedeb XIII. TAMARICACEiE. G-en. PL i. 159. 



{Tamariscineoe.') 



Undershrubs, shrubs, rarely trees or perennial herbs. Leaves alternate, 

 small, generally scale-like, sessile with a broad base, imbricating. Fl. 

 regular, usually bisexual, in spikes, racemes or panicles, in some genera 

 solitary. Sepals and petals pentamerous, sometimes tetramerous, generally 

 free. Stamens 5, 10, or numerous, insex'ted on an annular glandular disk, 

 anthers versatile, dehiscing longitudinally. Ovary syncarpous, of 3-5 carpels, 

 ovules numerous, on 3-5 placentas, which sometimes are enlarged, so as to 

 divide the ovary into cells. Capsule 3-5 valved. Albumen small or wanting, 

 embryo straight. 



Stamens 5 or 10, free, styles 3 or 4, short, each with a 

 large capitate stigma 1. Ta-Marix. 



Stamens 10, filaments united into a short tube, ovary 

 tapeiing into a short style with 3 sessile stigmab . 2. Mirk aria. 



1. TAMARIX, Linn. ; FL Brit. Ind. i. 248. 



Shrubs or small trees, medullary rays broad, very prominent on radial 

 section. Leaves minute, scale-like. In the juvenile state the leaves are 

 longer, lanceolate from a broad base, up to |- in. long. Fl. white or pink, in 

 spikes or dense racemes. Sepals and petals free. Stamens 5-10, inserted on 

 an annular disk. Ovary 1-celled, placentas at the bottom of the ovary, 

 styles 3 or 4, short. Seeds small, with a long coma, consisting of a setiform 

 axis studded with long hairs. Species 65, Europe, Asia, and Africa. 



Several species, m India, chiefly T. g&llica and jT. dioica^ are gregarious, covering 

 extensive areas on river hanks. On the Indus the seeds of these species, and of other 

 trees, -which are home down by the river, are deposited on the new formations of 

 alluvial land, which are submerged during the floods. "When the floods have subsided, 

 the seeds germinate, and in early spring these lands are covered with a dense forest of 

 Tmnarix, with a sprinkling of other trees, chiefly of Popuhis euj^lirafica.
