FOUQUIERACE. 
erect. Stamens 10; filaments filiform, exserted ; anthers ovate. 
Style exceeding the stamens. Cells of fruit 1-seeded when 
mature. A spinose shrub, with fascicles of obovate-oblong, 
membranous leaves in the axils of the spines. Flowers panicled, 
scarlet. It differs from the last genus in the placentas being 
drawn in more to the centre of the fruit.

Calyx free, or somewhat adnate to the very base of the ova- 
rium (f. 15. æ. f. f. 18. a.), usually of 2 sepals (f. 16. a. f. 18. a.), 
seldom of 3 or 5 (f. 20. a.), cohering at the base. Petals usually 
5 (f. 15. b. f. 17. b.), but sometimes 3-4-6, very rarely wanting 
altogether, either distinct (f. 18. b.), or cohering into a short 
tube at the base (f. 15. b.), alternating with the sepals when the 
number is equal. Stamens inserted along with the petals, irre- 
gularly into the base of the calyx, and sometimes perhaps in the 
torus, variable in number in the species of the same genus, all 
fertile ; filaments distinct, adnate to the base of the petals (f. 
15. g.), and usually opposite them where the number is equal ; 
anthers ovate, 2-celled, opening lengthwise, versatile (f. 18. c.). 
Ovarium one, usually roundish (f. 15. e.), 1-celled (f. 15. f.). 
Style sometimes single, filiform, cleft into numerous stigmas 
at the apex (f. 15. c.); sometimes wanting or nearly so; when 
this is the case the stigmas are distinct (f. 17. c.), and rise 
in numbers from the top of the ovarium. Capsule 1-celled, 
Opening either transversely (f. 15. f.), or by the 3 valves from 
the base to the apex; but they are also occasionally 1-seeded 
and indehiscent. Seeds numerous when the fruit is dehiscent, 
attached to the central placenta (f. 15. f.). Albumen farina- 
ceous. Embryo curved round the circumference of the albu- 
men, with a long radicle, and oblong cotyledons.—Fleshy 
Shrubs or herbs. Leaves alternate, rarely opposite, entire, 
usually succulent, without stipulas, or sometimes with membra- 
nous ones on each side of the petioles. Flowers axillary or ter- 
minal, usually expanding in the sun, and of short duration. 
The 1-seeded genera of this order agree in character with the 
order Paronychièæ, and the apetalous genera with the order 
Ficoidee. This order is related in nearly every point of view to 
Caryophillee, from which they scarcely differ except in their 
Perigynous stamens, which are opposite the petals when equal to 
them in number, and two sepals; the latter character is not, 
however, very constant. The presence of scarious stipulas in 
several Portulacee, although perhaps an anomaly in the order, 
indicates their affinity with Paronychièæ, from which the mono- 
Spermous genera of Portuldcee are distinguished by the want of 
Symmetry in their flowers, and by the stamens being apposite 
the petals, instead of the sepals. So close is the relationship

between these orders, that several of the genus Ginginsia in Por- 
tulàceæ have been referred to Pharnàceum in Caryophýlleæ, and 
several Portulàceæ have been described by authors as belonging 
to genera of Paronychite. De Candolle remarks, that his Gin- 
ginsia brevicatlis resembles certain species of Andrésace, and 
that Portulacee have been more than once compared to Primu- 
làceæ (mem. p. 14.), and the same author remarks in his prod. 
3. p. 351. that the genera with definite stamens, and hairy 
axillee approach Cácteæ, while the apetalous genera tend towards 
apetalous Ficoidee, 
Insipidity, want of smell, and a dull green colour, are the 
usual qualities of this order, of which the only species of any 
known use are common Parslane and Claytonia perfoliata, which 
resemble each other in properties.
