CRUCIFER^E. XLIII. MEGACARP^EA. XLIV. CREMOLOBCS. XLV. MENONVILI/EA. XLVI. EUCLIDIUM. 



XLIII. MEGACARPjE'A (from ficyac, megas, great, and 

 KapiroQ, karpos, a fruit; pods large). D. C. syst. 2. p. 417. prod. 

 l.p. 183. 



LIN. SYST. Tetradynamia, Siliculbsa. 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. 



1 M. LACINIA'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. Biscutella 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. Megacarpaea. Fl. June, July. Clt. 1818. 

 PI. i to 1 foot. 



f Species not sufficiently known. 



2 M. ANGULA'TA (D. C. syst. 2. p. 418.) leaves smooth, en- 

 tire, or repand-toothed. %.l 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 Megacarpcea, and very distinct from M. laciniata. 



Angular-leaved Megacarpaaa. PL 1 foot. 

 Cult. These plants are well adapted for rock- work. They 

 can only be increased by seeds. 



XLIV. CREMO'LOBUS (from Kpc^aw, kremao, to suspend, 

 and \w/3oc, lobos, a pod ; cells hanging from the axis.) D. C. 

 syst. 2. p. 418. prod. 1. p. 184. 



LIN. SYST. Tetradynamia, Siliculbsa. 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. PERUVIA'NUS (D. C. syst. 2. p. 419.) stems suffrutes- 

 cent ; leayes ovate, serrated ; style shorter than the pedicel of the 

 fruit, t? . G. Native of Guayaquil, and Chili. Biscutella, 

 Lam. diet. 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. SUFFRUTICO sus (D. C. syst. 2. p. 419.) stem suffrutes- 

 cent ; leaves oval-oblong, serrated ; style longer than the pedicel 

 of the fruit. Tj . G. Native of Peru. Biscutella suffruticosa, 

 D. C. diss. bisc. no. 7. t. 5. Easily distinguished from C.Chilen- 

 sis in the stems being frutescent, not herbaceous, as well as in 

 having broader, more serrated leaves. 



Shrubby Cremolobus. PL 1 to 2 feet. 



3 C. CHILE'NSIS (D. C. syst. 2. p. 419.) stem herbaceous ; 

 leaves oblong, almost entire ; style somewhat longer than the pe- 

 dicel of the fruit. Q. H. Native of Chili. Biscutella, Lag. 

 in litt. D. C. diss. bisc. no. 8. t. 6. Biscutella cuneata, Lag. 

 in hort. madr. 1815. p. 20. 



Chili Cremolobus. Fl. Ju. July. Clt. 1820. PI. foot. 



Cult. The genus Cremolobus 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, Siliculbsa. 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. LINEARIS (D. C. syst. 2. p. 420.) T. 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 Hespe- 

 ris tristis. 



Linear-leaved Menonvillea. Fl. May, July. PL 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.

 Euclidium,) or PLEURORHI'ZE^ (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 

 (f. 45. g. A.) when there is any.

 tire or toothed stem ones, with somewhat spicate erect racemes, 

 which are opposite the leaves, and small white bractless flowers.
