Stems several feet long, branches opposite and alternate, 1-3 in. high ; joints 

 -^ in. long, mouth slightly dilated. Spikes -1 in. long, joints in. deep, cup- 

 shaped, closely imbricate, fruiting very spongy with thin margins. Fruiting -perianths 

 3 together, shorter than the cup-shaped joints, closely appressed, laterally compressed, 

 spongy, gibbous towards the axis of the spike, flat towards the cup ; top broadly 

 truncate with a minute hole for the protrusion of the stigmas. Stamens not seen. 

 Utricle adnate to the perianth, ovoid, compressed, indurated. Seed free, erect, orbi- 

 cular, testa membranous ; embryo and albumen of the genus.

DECCAN PENINSULA, Herb. Wight (Kew Distrib. No. 2474, 2475). CEYLON, 

 Thivaites. DISTEIB. Mediterranean, W. Asia, Trop. Africa. 



Apparently tall, stem below as thick as the little finger ; branches many, erect or 

 ascending, slender. Malefloivers (in threes, consisting of 3 stamens each in a mem- 

 branous perianth ?). Female spikes about as long as broad, obscurely 2-lipped. 

 Utricle flagon-shaped, enclosed in the broadly ovoid spongy perianth, which has a 

 minute hole for the protrusion of the stigmas. Seeds orbicular, testa black thinly 

 < rustaceous ; embryo and albumen of the genus. I am not quite sure as to the 

 structure, &c., of the male flowers (No. 2474), and am doubtful as to its distinctness 

 from A. fruticosum. It is, I think, monoecious. 



XIII. SALICORNIA, Linn. 



Herbs or shrubs with the habit of Arthrocnemum, but with the flowers 

 sunk in cavities of the joints. Perianth obpyramidal, 3-4-toothed, fruiting 

 spongy. Stamens 1-2. Utricle included in the spongy perianth, membranous ^ 

 .stigmas subulate. Seed erect, compressed, testa hispid with hooked hairs, 

 albumen ; embryo conduplicate, radicle inferior parallel to the folds of the 

 cotyledons. Species 8, temperate and tropical.
