Glabrous and 



cvlin- 



very rigid, appiirently viscid when young ; branchlets slightly angular, soon 

 terete. Phyllodia linear-lanceolate, somewhat falcate, mostly acuminate, but 

 not pungent, narrowed at the base, 2 to 4 in. long, 2 to 4 lines broad, very 

 rigid, with 5 to 7 very prominent nerves, the central one usually thick and 

 the margins often, but not always, much raised. Spikes sessile, solitary or 

 in pairs, ^ to f in. long. Flowers dense, mostly 4-merotis. Sepals iiarrow- 

 sratlmlatc, ciliate, distinct. Petals united at the base. Pod glabrous, spirally 

 twisted into i\ dense compact cylinclrical coil of about 4 lines diameter; valves. 

 coriaceous, flat, with thickened margins. Seeds ovate, last 2 or 3 folds of 

 the fuuicle filiated into an aril nearly as large as the seed, but under it.

. 224. A. Dallachiana, F. Mndl. Fragm.. i. 7, and PL Fid. ii. 32. A 

 tree of 20 to 30 ft., glabrous, with angular usually glaucous branchlets. _ 

 I'hyllodia lanceolate-falcate, obtuse or with a callous point, much and obliquely 

 iiarrow(;d towards the base, 3 to 6 in. long, often 1 in. broad in the middle, 

 coriaceous, with 2 to 5 or 6 more or less prominent primary nerves and con- 

 spicuously reticulate between them. Spikes usually in pairs, sessile, 

 ^rieal, 1 to 1| in. long. Bracts peltate, remarkably conspicuous and densely 

 imbricate with the flower buds. Flowers mostly 4-mei-ous. Calyx obtusely 

 toothed, more than half as long as the corolla. Petals smooth, united to the 

 n»id(lle, with rather prominent midribs. Pod linear, straight or nearly so, 2 

 to ^ lines broad ; valves convex over the seeds, flat and narrower between 

 *etu Seeds ovoid, longitudinal, the last 2 or 3 folds of the tunicle much 

 ^l«ted, the last forming a cup-shaped aril under the seed.
