40 TAMARISCINE E. TricHaurus. * 
I. TAMARIX. Linn. ; Lam. ill. t. 213. f. 1. 
Sepals 5, distinct. Petals 4-5. Stamens 4-10, equal, inserted each on 
and connecting two of the teeth of the torus, distinct, without any interme- 
diate gland or membrane, Torus fleshy, scutelliform, supporting the ova- 
rium, with twice as many teeth on the margin as there are stamens. Styles 
2-4, usually 3. Seeds not beaked, with a simple pappus-like coma at their 
extremity.—Flower-bearing branchlets, usually arranged in panicles. 
141. (1) T. gallica (Linn. :) young branches glabrous : leaves amplexicaul, 
glabrous: stamens 5: torus 10-toothed: styles 3, longish: capsules attenu- 
ated (not turgid).—T. gallica var. Indica, Ehrenb. ; Wight! cat. n. 950.—

* 142. (2) T. dioica (Roxb.:) young branches glabrous: leaves sheathing, 
glabrous: flower-bearing branchlets about as long as the dense terminal 
spikes: flowers dicecious: stamens 5: styles 2-3, elongated beyond the co- 
rolla.—Rowb. hort. Bengh. p. 22 ; fl. Ind. 2. p. 101; Roth. nov. sp. p.185; - 
Wall.! L. n. 1241.—T. articulata, Wall.! L. n. 3156. b (male). 
Allied to T. articulata, Vahl, but that species appears to be bisexual: 
also to T. Pharos, Ham., which is also dicecious, but has lax spikes nearly 
sessile on the branches almost without the intervention of a leafy branchlet. 
We insert this, because we have reason to believe that Wall. L. n. 37506. € 
belongs to it. Dr Wight's specimen sent to Dr Wallich was obtained from 
the Madras herbarium, and corresponded consequently to that described by 
Roth.

Sepals 5. Petals 5, slightly unequal. Stamens 10, the alternate ones j 
shorter, inserted between and alternating with the teeth of the torus: fila- i 
ments distinct, not connected by a membrane. Torus fleshy, cup-shaped, E. 
surrounding the base of the ovarium, with as many teeth on the margin as - 
stamens. Styles 3. Seeds rostrate: beak straight, feathered with long 
spreading hairs.—Young leaves sheathing. Corolla and capsule the largest 
of this natural order. : 
,,Chis genus is mostly allied to Myricaria (Tamarix, Lam. ill. t. 213. f. 2.), but 
differs from it by the distinet ene and stigmas, and by the torus being only ex 
anded into a tooth, instead of a connecting membrane, between the stamens 
rom Tamarix the beaked seed and other characters will readily distinguish it. —
