XLIII. MEGACARPÆ'A (from peyac, megas, great, and 
kaproc, karpos, a fruit; pods large). D. C. syst. 2. p. 417. prod. 
l. p. 183. . 
Lis. syst. Tetradynamia, Siliculdsa. Silicle flat, biscutate, 
emarginate at each end. Cells much compressed, 1-seeded, 
winged on the margin and united laterally to the axis. Style 
none. Radicle, ascendant. Perennial herbs, with a scaly neck and 
multifid leaves. Flowers in panicles small, perhaps yellow. Pods 
large. 
i M. tacinia’ta (D. C. syst. 2. p. 417.) leaves villous ; ra- 
dical ones stalked, pinnate-parted, with deeply toothed or cut 
lobes. Y. H. Native of Siberia, in the Kirghisian-steppe, 
and on the gypsaceous hills in the desert called Arsagar, beyond 
the river Volga. Biscutélla megalocarpa, Fisch. in litt. D. C. 
diss. bisc. no. 5. t. 3. Flowers small, but not sufficiently known. 
Stem furnished at the neck with the vestiges of the petioles of 
preceding year. 
Jagged-leaved Megacarpea. 
Pl. å to 1 foot. 
Fl. June, July. Clt. 1818. 
t Species not sufficiently known. 
2 M. anouta‘ra (D. C. syst. 2. p. 418.) leaves smooth, en- 
tire, or repand-toothed. %.? H.? Native of Siberia. The 
description of this plant has been taken from a very incomplete 
specimen, by De Candolle, but from it, it is evident, that it is a 
species of Megacarp@ a, and very distinct from M. laciniàta. 
Angular-leaved Megacarpea. Pl. 1 foot. 
Cult. These plants are well adapted for rock-work. They 
can only be increased by seeds. 
XLIV. CREMO’LOBUS (from xpepaw, kremao, to suspend, 
and Awfpoc, lobos, a pod; cells hanging from the axis.) D. C, 
syst. 2. p. 418. prod. 1. p. 184. 
Lin. syst. Tetradynàmia, Siliculdsa. Silicle stalked, flat; 
biscutate. Cells marginate, hanging from the top or end of the 
axis. Style somewhat pyramidal. Seed solitary in each cell. 
Radicle ascending. Smooth herbs or sub-shrubs with round 
stems, and ovate or oblong, serrated, or somewhat entire cauline 
leaves, and many-flowered elongated racemes, with bractless fili- 
form pedicels and yellow flowers. 
1 C. Pervuvia'nus (D.C. syst. 2. p. 419.) stems suffrutes- 
cent ; leaves ovate, serrated ; style shorter than the pedicel of the 
fruit. bh. G. Native of Guayaquil, and Chili. Biscutélla, 
Lam. dict. 3. p. 620. D. C. diss. bisc. no. 6. t.4. Leaves 2 or 
3 inches long. 
Peruvian Cremolobus. PI. 1 or 2 feet. 
2 C. surrrutico sus (D. C. syst. 2. p. 419.) stem suffrutes- 
cent; leaves oval-oblong, serrated; style longer than the pedicel 
of the fruit. h.G. Native of Peru. Biscutélla suffruticdsa, 
D. C. diss. bise. no. 7. t. 5. Easily distinguished from C.Chilén- 
sis in the stems being frutescent, not herbaceous, as well as in 
having broader, more serrated leaves. 7 
Shrubby Cremolobus. Pl. 1 to 2 feet. 
3 C. Cuire’nsis (D. C. syst. 2. p. 419.) stem herbaceous ; 
leaves oblong, almost entire ; style somewhat longer than the pe- 
dicel of the fruit. @©.H. Native of Chili. Biscutélla, Lag. 
in litt. D. C. diss. bisc. no. 8. t. 6. Biscutélla cuneata, Lag. 
in hort. madr. 1815. p. 20. 
Chili Cremolobus. Fl. Ju. July. Clt. 1820. Pl. 4 foot. 
Cult. The genus Cremélobus is scarcely worth cultivating 
except in botanic gardens. A mixture of loam, peat, and sand, 
will suit the two green-house species well. The hardy annual 
kind should be sown in front of a south wall in the common 
earth, about the middle of April. The only way of increasing 
this genus is by seeds ; however young cuttings of the two green- 
house species, when procured, may be tried under a hand-glass.

XLV. MENONVI'LLEA (in honour of N. C. Thiery de` 
Menonville, who introduced into Spanish America the Cactus 
Coccinellifera as well as the Cochineal.) D. C. syst. 2. p. 419. 
prod. 1. p. 184. 
Lin. Syst. Tetradynamia, Siliculdsa. Silicle somewhat sti- 
pitate, biscutate (f. 46. n.) Cells with the margin expanded into 
a wing, and as if it were finishing the parallel disk (f. 46. n.). An 
herb with a thick root and radical linear leaves, and terminal ra- 
cemes with bractless pedicels and dark or sad-coloured flowers. 
1 M. merearis (D. C. syst. 2. p. 420.) 4%.G. Native of 
Peru and Chili. Radical leaves linear, entire, but sometimes, al- 
though rarely, grossly and irregularly toothed towards the top. 
Petals linear, twice the length of the calyx. Deless. icon. sel. 2. 
p. 56. The colours of the flowers are nearly like those of Héspe- 
ris tristis. 
Linear-leaved Menonvillea. Fl. May, July. PI. 1 foot. 
Cult. Menonvillea is not worth cultivating except in botanical 
gardens. A mixture of sand, loam, and peat will answer it well ; 
and it should be increased by seeds. l

Euclidium,) or PLEURORHI'ZEZ (See Sub-Order I.) NU-

syst. 2. p. 420. prod. 1. p. 184. Silicle indehiscent, with con- 
cave, indistinct (f. 46. d.), or not separating valves, and some- 
times with hardly any trace of a dissepiment. Seeds oval, very 
few. Cotyledons flat, accumbent, parallel with the dissepiment 
(£. 45. g. h.) when there is any.

kleidoo, to shut up; because of the well-closed seed-pods. )
