46. A. tetragonocarpa, Meissn. m PL Prelss. i, 4. A glabrous un- 



dershrub, with erect slender rush-like stems of 1 to 2^ ft., slightly branrhed 

 and nearly leafless. Phyllodia mostly reduced to small striate scales at the 

 base of the branches, 1 or 2 often filiform, terete, resembling the branches, 

 the lower ones of the young plant occasionally bipinnate as in other phyllo- 

 dineous species. Peduncles short, often 2 or 3 together, bearing ahead of 3 

 or 4 flowers, occasionally reduced to a single one, 4-merous and oblong in the 

 bud. Calyx short. Petals rigid, striate, nearly 1^ lines long. Pod stipi- 

 tate, linear-falcate, about ] in. long, witli a very prominent longitudinal angle 

 on each side of each suture. Seeds longitudinal, the last fold of the funicle 

 dilated into a small turbinate almost cup-shaped aril under the seed, with a 

 ■ filiform fold below \i.— Tetracheilo8 Meismeri, Lehm, in PL Preiss. ii. 368.

Var. scabra, Phyllodia long, rigid, proiiiiiiently 1-nerved, glabrous. Pod not seen, 

 riowers as ia the ordinary form, —A single speoimeu from Oldfield. 



The longitudinally 4-angled pod, upon which Lefamann founded the genus Teiracheiloh 

 occurs also in A. sienopieray a species widely differeut iu several other respects, and to a cer- 

 tain degree also ia some, of the Julijlorm. 



4^. A. restiacea^ Benth. in Hook. Land. Journ, i. 3. A glabrous un- 

 dershrub or shrub, with rush-like branches somewhat angular or striate, leaf- 

 less or with a few slender terete phyllodia, scarcely to be distinguished from 

 the branches. Flower-heads globular, several in a'^racenie, covered when very 

 young by imbricate scales very early deciduous. Flowers mostly 5-merous, 

 usually 20 to 30 in the head. Calyx small, thin, irregularly lobed. Petals 

 smooth. Pod (according to Lehmann) stipitate, linear, moniliform, with re- 

 ticulately veined coriaceous valves.— Meissn, in PL Preiss. i. 3, ii. 199; tA^ 

 thonaulhus rediacem, Lehm. in PI. Preiss. ii. 363.

 find in our libraries, appears to be, from the characters copied into Walp. Ann. i. ^^^y 

 same as A, restiaeea, and certainly not A. sqitamata, Lindl. ^^ 



The imbricate scales covering the very young racemes, which induced Lelimanutoprop 

 his genus Chitlionanihus, occur also in A. sfiuamata, in A. maveolens, and in some o 

 species widely differing in other characters.
