loam should preponderate to the aiii of about two- 
thirds, and some rotten cow-manure may be added. Pro- 
pagated from seeds, which should be sown in a compost 
similar to above, and placed in a moist gentle heat. They 
are employed with much success for the decoration of 
drawing rooms and dinner tables. Of course, the descrip- 
tions refer to the plants in a mature state, but they may 
be grown for many years before reaching the dimensions 
given.

the best and oldest species in cultivation, very effective, in a 
young state, for dinner table decoration. It produces the Betel 
nut, of which enormous quantities are used in India.

Alsinee. A very large genus of hardy herbaceous plants, 
consisting of about 150 species. It is distinguished by 
having generally three styles. The perennials only are 
- worth growing; these are extremely pretty little alpine 
plants, and will thrive in any ordinary soil in exposed 
places; the rarer species may be grown in small pots, well 
drained, in a mixture of sand, loam, and leaf soil, or in well- 
drained crannies of the rockery. They may be increased 
_ by either division, seeds, or cuttings; the latter, placed 
under a hand-glass, will root “freely. The best time to 
_ divide the plants is early spring, or July and August. 
_ Seeds should be sown in spring in a cold frame.
