Order XXI. TAMARISCINEiE. 

 By B. L. Robinson. 



Trees, shrubs, or rarely perennial herbs, with alternate entire thickish often 

 small and scale-like exstipulate leaves and regular perfect or rarely dioecious 

 Howers. Sej^als 4 to 5, free nearly or quite to the base and imbricated. Petals 

 of equal number, free or connate into a gamopetalous 4-5-lobed corolla, inserted 

 beneath and outside of a hypogynous or nearly hypogynous disk. Stamens 4 or 

 5 to X ; filaments free or connate at the base or rarely united into a tube for most 

 of their length ; anthers oblong, bilocular, introrse, often appendaged at the apex. 

 Ovary single, free, unilocular ; carpels, parietal placentiB, and free styles or stigma- 

 lobes 3 or 4 each ; few or numerous erect ovules anatropous with ventral rhaphe. 

 Fruit capsular ; valves as many as the styles ; seeds few to many, often pro- 

 vided with a hairy appendage or less frequently winged ; embryo straight ; 

 albumen often scanty or none. — A small but composite order, represented in our 

 limits only by the sparingly naturalized Tamarix of cultivation and the anoma- 

 lous genus Fouquieria, which shows almost equal affinity to Crassulacece. 



1. TAMARIX. Sepals 4 to 6. Petals free nearly or quite to the base. Stamens 4 to 12, 

 distinct or nearly so. Ovary ovate-attenuate, with 3 to 5 short thickish styles. Placentae 

 multi-ovulate, essentially basal. Leaves very small and scale-like. 



2. FOUQUIERIA. Sepals 5, unequal. Petals united into a tubular gamopetalous 5-lobed 

 corolla. Stamens 10, 15, or cc,free or nearly so. Ovary ovoid, not attenuate; stj'les 3, 

 slender, free or united ; placentae parietal, extending the whole length of the ovary and 

 more or less intruded as partial septa. Leaves fleshy, obovate. Flowers showy.
