92 PARONYCHIEA. X. Porycarpma. 
12 P. crasriroxia (D. C. l. c. and mem. par. t. 5.) stems 
erect, branched, suffruticose; branches pubescent ; leaves gla- 
brous, oblong-linear, bluntish, twice the length of the stipulas ; 
cymes terminal, dense, many-flowered, in crowded heads. h.? 
¥.?S. Native of Sierra Leone. This species differs from P. 
tenuifdlia in the leaves not being subulate, nor keeled, nor with 
revolute edges; in the stipulas being large, and in the flowers 
being capitate. 
Glabrous-leaved Polycarpea. PI. 1 foot. 
13 P. rrngarrronia (D. C. l.c. and mem. par. t. 6.) stems 
erect, or somewhat ascending at the base, branched ; branches 
pubescently hairy; leaves linear, elongated, pubescent, 3 times 
longer than the stipulas; cymes crowded into a dense terminal 
roundish head. ©. F. Native of Senegal. Paronychia lineari- 
folia, D.C. in Lam. dict. 5. p. 26. Tllécebrum linearifdlium, 
Pers. ench. 1. p. 261. Alternanthéra erécta, Rchb. in Sieb. pl. 
exsic. seneg. no. 60. Habit of Celdsia, but the characters are 
those of Polycarpe‘a. 
Linear-leaved Polycarpzea. Pl. 1 foot. 
14 P. rranKENtoipEs (Presl. in Heenk. reliq. 2. p. 6.) stems 
much branched, diffuse, procumbent, roughish ; branches oppo- 
site ; leaves opposite, oblong, obtuse, clothed with rough pubes- 
cence ; flowers in dichotomous corymbose panicles ; sepals blunt- 
ish, pilose. ©.H. Native of the Island of Luzon. 
Frankenia-like Polycarpeea. Pl. procumbent. 
+ Species not sufficiently known. 
15 P. carnosa (Chr. Smith in Buch. can. p. 142.) stem 
shrubby ; leaves 6 in a whorl, fleshy: lower ones spatulate : 
upper ones lanceolate ; stipulas very short, jagged. h.G. Na- 
tive of the Canary Islands. 
Fleshy Polycarpea. Shrub 1 foot. 
16 P. Smrrui (Link in Buch. can. p. 142.) leaves 6 in a 
whorl, linear, glabrous, obtuse ; stipulas very short; panicle 
dichotomous; branchlets divaricate; bracteas ovate, shorter 
than the calyx. h.G. Native of the Canaries, in the island 
of Palma, at Cumbre de Caldera. Very nearly allied to P. stel- 
làta but differs in the panicle. 
Smith's Polycarpea. Pl. 4 to 4 foot. 
17 P.? mrnuartioipes (D.C. prod. 3. p. 875.) stem shrubby, 
branched; branches tomentose; leaves subulate, crowded; 
cymes axillary, few-flowered. h.F. Native of the south of 
Spain. Méllia minuartioides, Spreng. mant. 1. p. 37. ex Schultes. 
Lahaya minuartioides, Schultes, syst. 5. p. 406. This is a very 
doubtful species, being omitted in Spreng. syst. 
Minuartia-like Polycarpea. FI. Ju. Aug. Clt. 1826. Pl. 4 ft. 
18 P.? pepre’ssa (D.C. l.c.) stems herbaceous, depressed, 
diffuse; leaves opposite, crowded into something like whorles, 
wedge-shaped ; stipulas 4-cleft? flowers terminal, triandrous ; 
calyx fleshy; petals linear, 4-toothed at the apex. ©. F. 
Native of the East Indies. Pharnaceum depréssum, Lin. mant. 
p. 564. Loeflingia I’ndica, Retz, ind. p. 48. Roxb. fl. ind. 1. p. 
169. This plant is certainly neither a Leeflingia nor a Pharna- 
ceum ; from the stipulas and many-seeded capsule, it agrees more 
nearly with Polycarpe‘a, but differs in the fleshy calyx, and 
triandrous flowers : perhaps it is more nearly allied to Pollichia, 
but the calyx in this plant is said to be 5-parted. 
Depressed Polycarpea. Pl. depressed. 
Cult. The seeds of the annual species of Polycarpe‘a should 
be reared on a hot-bed early in spring. The perennial and 
shrubby species being either green-house, or frame plants, 
require to be kept in their respective places: they are easily in- 
creased by cuttings under a hand-glass, those of the stove species 
in heat. 
XI. STIPULICIDA (from stipula, a stipula, and cedo, to 
cut; stipulas cut or jagged). Michx. fl. bor. amer. 1. p. 26. t.

p- 375.—Polycarpon species, Pers. Roem. and Spreng. 
Lin. syst. Tridndria, Monogynia. Calyx 5-parted; lobes 
oval, with membranous margins. Petals 5, cuneate-oblong, en- 
tire. Stamens 3, inserted with the petals into the disk or torus, 
Style short; stigmas 3. Capsule l-celled, 3-valved. Seeds 
few, fixed by funicles to the central placenta.—Small perennial 
dichotomous herbs, native of North America. Radical leaves 
almost like those of Polycarpe‘a Teneriffe, ovate, petiolate; 
cauline leaves sessile, opposite, small. Stipulas jagged. Flowers 
small, tern, terminal. An intermediate genus between Poly- 
carpon and Polycarpé a, from the sepals being flattish as in Po- 
lycarp@‘a, and in the stamens being 3, as in Polycarpon ; but 
differs from both in the petals and stamens being expressly hypo- 
gynous according to Richard in Michx. l. c. ; the genus therefore 
perhaps ought to have been placed in Caryophillee.

Carolina, in sandy arid places. Polycárpum stipulifidum, Pers. 
ench. 1. p.111. Pursh, fl. amer. sept. 1. p. 90. Plant gla- 
brous, setaceous, erect, many times dichotomous. 
Setaceous Stipulicida. Pl. 4 foot.

XII. BALA’RDIA (in honour of M. Balard, of Montpelier, 
who was the first to detect a new chemical principle called 
brome). St. Hil. fl. bras. 2. p. 180. 
Lin. syst. Di-Tetréndria, Trigynia. Calyx 5-parted almost 
to the base, permanent ; segments flattish. Petals none. Sta- 
mens 2-3-4, inserted in the receptacle. Styles 3, very short, 
papilliferous inside. Capsule 3-valved, many-seeded ; valves 
membranous. Seed subovoid, fixed to the central placenta.— 
An annual, branched, dichotomous herb, with opposite, stipu- 
late leaves, and cymose flowers. 
1 B. Prarte’nsis (St. Hil. fl. bras. 2. p. 181. t. 111.) leaves 
linear, about equal in length to the internodes, mucronulate j 
cymes branched, many-flowered. ©. H. Native of Brazil, in 
the southern part of the province of Cisplatine, near Povo de 
Canelones; and in the western part near Pueblo de las Viboras; 
also of Buenos Ayres. 
Plate Balardia. Pl. 4 foot. 
Cult. The seeds of this plant should be sown on a hot-bed 
in spring, and the plants may be planted out in the open border 
in the month of May, in any warm dry situation. Not worth 
cultivating, excepting in a botanic garden. 
XIII. AVE'RSIA (in honour of M. Avers, D.M. P., who 
has written a dissertation on the Nicotiana Tabécum, in which he 
treats of its various qualities). St. Hil. fl. bras. 2. p. 184. 
Lin. syst. Tridndria, Monogijnia. Calyx deeply 5-parted, 
permanent ; lobes thickened in the middle, keeled. Petals 5, 
inserted in the bottom of the calyx. Stamens 3, inserted with 
the petals; filaments dilated at the base, joined to the petals 
and together at the base. Style 1, trifid ; lobes papilliferous 
inside. Capsule 3- valved, many-seeded ; valves membranous: 
Seeds fixed to the central placenta, cylindrical. Embryo in the 
middle of fleshy albumen, not at one side as in Polycarp@ a~ 
A trailing branched herb, with opposite stipulate leaves ; young 
leaves or abortive branches in fascicles in the axils of the older 
leaves. Cymes branched, many-flowered. = 
1 A. FRANKENIOÌDES (St. Hil. 1l. c. t. 112.) stems trailing, 
branched ; leaves lanceolate, bluntish, narrowed into the petiole, 
pubescent; cymes many-flowered ; segments of calyx obtusé 
pubescent; petals and stamens one half shorter than the caly%
