Halopeplis.| CVII. CHENOPODIACEH (BAKER AND CLARKE). 85 
Nile Land. Nubia: coast region, Bent ! 
Also in North-east Africa and Arabia. 
The Mediterranean H. amplexicaulis resembles altogether the young examples of 
H. perfoliata, but appears never more than annual, and is maintained as a distinct 
species by Boissier. 
6. HALOCNEMUM, M. Bieb.; Benth. et Hook. f. 
Gen. Pl. iii. 64. 
Flowers very small, 2-sexual. Perianth of 3 unequal obovate seg- 
ments united below. Stamen 1. Ovary ovoid, narrowed upwards; 
style short, branches 2, sometimes 3; ovule 1, suspended on a basal 
funicle. Seed vertical; embryo peripheric round the albumen.—A 
small shrub; stem continuous, the branchlets and spikes apparently 
articulated. Leaves 0. Bracts in small spikes, with usually 3 flowers 
under each. 
Species 1, also in Europe, North Africa, the Orient and Central Asia,

7. ARTHROCNEMUM, Moquin; Benth, et Hook. f. 
Gen. PI. iii. 65, 
Flowers very small, 2-sexual. Perianth funnel-shaped, shortly 
3-4-lobed. Stamens 2-1. Ovary ovoid; style short, branches 2; ovule 
1, suspended ona basal funicle. Seed vertical ; embryo peripheric round 
the albumen.—Small shrubs; stem branched, of short joints. Leaves 0. 
Flowers in cylindric dense spikes; in clusters of 3 sunk in the hollows 
of the joints. 
Species 7, in saline marshes of the Old World. 
The seed is very much like that of Ficoidee or small Caryophyllacee. From the 
“eye” lines of longitudinal cells radiate; as these approach the round back of the 
seed the cells shorten, so that the curved back of the seed is covered by subquadran- 
gular cells, usually inflated; this inflation is sometimes sufficient to make the seed 
subpapillose on the back, The degree to which these markings are to be seen in the 
fully ripe seed varies considerably in those examined from one plant. Volkens’ 
picture in Engl. & Prantl, Pflanzenfam. iii. 1A, fig. 35, M, is a very rough imperfect 
view of an average seed through a pocket lens. The characters of the seed have been 
much used in distinguishing the species of this genus, but in my opinion are of little 
value,
