104 NEW AND RARE TLANTS. 



ference to the Euphorbia Splendens : the length of time the involucre 

 continues expanded, the elegant growth of the plant if properly 

 managed, gives it a decided pre-eminence among stove plants. This 

 lovely plant was introduced into Germany 8 few years ago, through 

 Baron Kerwinski, and introduced from thence into Britain by Mr. 

 Runch. It is a native of Mexico. 



Cultivation. — Mix equal quantities of loam, peat, and rotten cow 

 dung with a little sand. If cow dung cannot be got, any very rotten 

 manure will do. Cuttings will strike very freely in sand. After 

 they are struck, pot them off into sixty pots, and shift them regularly 

 as the pots become fidl of roots. It is very necessary to stop the 

 terminal shoots frequently, otherwise the plant will grow very de- 

 formed, or, as gardeners term it, be long-legged. When the pot is 

 full of roots, the plant will flower, even if it be very small ; so it 

 must be observed, that if cultivators desire to have large plants, they 

 must shift them frequently until they wish them to show their in- 

 volucre. 



t I am quite surprised that you have not more communications on 

 the cultivation of Orchidese plants. I intend to send you a few notes 

 on the subject, and will endeavour to elucidate the cultivation of that 

 difficult but highly interesting tribe of plants.

LIST OF NEW AND RARE PLANTS. 



FROM PERIODICALS. 



1. Cai.ostemma i.utea, Yellow. (Bot. Reg. 19, 1840.) Amaryllidaceae. 

 Hexandria Monogynia. A bulbous plant, a native of New Holland, from 

 whence bulbs are imported into this country, and it is found to thrive best in a 

 greenhouse, grown in peat, loam, and sand. Like other bulbous plants, it requires 

 its season of rest, or will not bloom ; and as soon as it begins to push, water 

 being given liberally, it causes it to flower. The flowers, which are an inch across, 

 are produced in umbels, each having from twelve to twenty flowers, of a deep 

 yellow colour. 



2. Ceanothus pali.idus. Pale- flowered. (Bot. Reg. 20, 1840.) Rhamnaceae. 

 Pentandria Monogynia. This beautiful flowering shrub we saw in bloom in 

 the Loudon Horticultural Society's garden, where it blooms very freely, trained
