Gen. Char. Sterile Flower (fig. 5.) and united flower (fig. 1.), * 
which two are mostly barren. Calyx inferior, concave, permanent, 
in 5 deep, equal, egg-shaped, concave segments, thin or membra- 
nous at the margins. Corolla none. Filaments (see figs. 1 & 5.) 5, 
awl-shaped, from the bottom of the calyx, opposite to its segments, 
and about as long. Jlnthers of 2 round lobes. Germen superior, 
orbicular, usually very imperfect. Style (when present) short, 
deeply divided. Stiyma simple, spreading. Seed 1, round, de- 
pressed, wrapped in a thin close pellicle, and covered by the closed 
permanent, 5-angled calyx. It is rare that our British species form 
any seed in these flowers. Fertile flower (fig. 2.) on the same 
plant. Calyx inferior, in 2, deep, large, flat, upright, compressed, 
egg-shaped, bluntish segments. Corolla none. Stamens none. 
Germen (see fig. 2.) superior, compressed. Style (see fig. 2.) short, 
deeply divided. Stigmas simple, spreading. Seed (see figs. 3 & 4.) 1 , 
round, compressed, wrapped in a thin close pellicle, and enclosed 
between the enlarged, converging, heart-shaped segments of the 
calyx. 
. The 5-cleft calyx ; and the 5 stamens of the sterile and of the 
united flowers; and the 2-parted calyx ; the bifid style; and the 
single seed of the fertile flowers; will distinguish this from other 
genera, without a corolla, in the same class and order. 
The presence of the fertile or pistiliiferous flowers with a 2-parted 
calyx, is the only mark of distinction between this genus and that 
of Chenopodium ; see t. 352. 
Seven species British. 
A 'TRIPLEX PA'TULA. Spreading Halberd-leaved Orache. 
Delt Orrach. Common wild Orache. Fat-hen. Lambs-quarters. 
Eig. 1. A Flower, with both Stamens and Pistil. — Fig. 2. Flower with Pistil 
only. — Fig. 3. A Seed. — Fig. 4. The same, accompanied with the 2 enlarged valves 
of the calyx of the pistiliiferous Flower. — Fig. 5. A Flower with stamens only. — 
Fig. 6. A Spike after flowering, with the valves of the calyx of the pistiliiferous or 
fertile Flowers enlarged. — Figs. 1 & 5. slightly magnified. 
* From o, Gk. not ; and traphein, Gk. to nourish; as affording little or no 
nourishment. 
+ The 23rd Class of the Linnaean Artificial System ; it contains those plants 
which have some flowers with both stamens and pistils ; others with stamens only ; 
and others with pistils only, either on the same plant, or on 2 or 3 distinct ones of 
the same species ; such difference in the essential organs being moreover accom- 
panied with a diversity in the accessary parts of the flowers,
