As to culture, these are all stove plants, and in this country require the assistance of the tan-bed to make them flourish. Rich earth and great plenty of pot-room are likewise requisite, and also a large portion of water when they are vegetating briskly, but less when they are almost at a stand,--which is sometimes the case,--although they are never perfectly quiescent, as is common in the neighbouring genus Amomum. They are propagated easily by parting their perennial roots. [Illustration] PLATE CCCCXXII. CROTOLARIA JUNCEA. _Rushy-stalked Crotolaria._ CLASS XVII.

One of the wings. 4. The keel. 5. The chives. 6. The same spread open. 7. The seed-bud and pointal. The species of Crotolaria here represented is a native of Malabar and the coast of Coromandel. It was obligingly sent us in bloom last August by the Hon. Mr. Irby, of Farnham Royal, Bucks, and was raised by him from East Indian seeds. Its root is annual; and the plant, in consequence of it, admits of increase by seeds only, which should be sown early on a hot-bed, with the most tender annuals, and the young plants when large enough should be transplanted into separate pots of rich earth; and after they have sufficiently recovered the effects of removal, they should be taken into the hot-house, the assistance of which is requisite to bring them to maturity. They rise with slender and rather rushy stems, which are but slightly branched, to the height of two or three feet, and make a fine appearance when in flower; but they are, like many other tender leguminous plants, very subject to the annoyance of insects, and more especially to that almost indestructible pest of stoves, the red spider; the best mode of destroying which is that of steaming the plants; that is, keeping them well watered, and in a hot and humid air. Some of our friends conceive this plant to differ from that which is figured in the Botanical Magazine, No. 490. It is true, I found the seed-bud quite silky; and if the full grown pod (which I never saw[F]) should likewise be so, it would certainly be worthy distinguishing from that plant, which is said to have smooth, and therefore, in all probability, naked pods.
