"Thread-shaped ; branches very numerous, opposite or alter- 
nate, often ending in forks. Bladders egg-shaped, in the sub. — 
stance of the stem and the branches, distant, an awl-shaped 
leaf at the side of each. Linn. Six or » inches long, . cartilagi« 
nous, tawny olive, Bladders oblong, placed ata little distance, 
3 or 4 one above another, each with one or two little thorns. 
When in fruit, the ends of the branches also swell, and are co- 
vered with numerous wart-like substances, each with a puncture 
in the centre and within full of seeds. Licurr. 924. The seeds 
are not in the cavity,: but seem to be placed beneath the outer - 
oat of the branches, rather in an annular form, VeLiey *.. 
granulations: placed under the outer. coat.,of the branches are 
dark coloured and have a) pore or hole opening externally. — 
There are other protuberances in the, branches, not dark colour-
