CLASS II.—MONOCOTYLEDONOUS PLANTS, OR ENDOGENES. 
order butomeae. —The Flowering Rush Tribe. 
Limnocharis Humboldtii. —Humboldt’s Limnocharis. This was received by 
Dr. Hooker some time ago, from Mr. Tweedie, of Buenos Ayres, gathered in 
pools and ditches of fresh water, near that city. Seeds were likewise received 
from the same source, at the botanic garden, Liverpool, when plants raised from 
them were successfully treated in the Aquarium, by Messrs. Shepherd, and the 
handsome and delicate yellow flowers burst open in great perfection, in April 
1833.— Bot. Cab. Culture—Of course it is a stove plant, it should be potted in 
rich loamy soil, and placed in a large pot or pan of water. They may probably 
be increased by seeds. 
smilacEjE. —The Smilax Tribe. 
Trillium erectum viridifiorum. —Upright-stalked Green-flowered Trillium. 
This plant was received by the Glasgow botanical garden, from Canada, by fa¬ 
vour of Mr. Cleghorn, and it flowered under a frame in the month of April, 
1833.— Bot. Mag. Culture—All the species are hardy or nearly so, and if 
planted in peat, in a shady situation, either in a bed or in pots, and kept moist 
will thrive very well. They increase slowly by dividing the roots. 
amaryllide^e. —The Amaryllis Tribe. 
Cyrtanthus spiralis. —Spiral-leaved Cyrtanthus. This is a native of South 
Africa, near Algoa Bay; its flowers are bright red. Culture—It requires the pro¬ 
tection of a greenhouse, and may be potted in sandy peat earth.— Bot. Cab. 
Effects of Electricity on Plants. —Many experiments in electrifying 
plants have been made by M. Nuneberg and the Abbe Nollet. According to the 
reports of the former, most of them increased in height, and flourished far be¬ 
yond others not electrified. Some bulbous roots, he says, which had been fre¬ 
quently electrified, grew eighty-two lines and a half, whilst others of the same 
species not electrified, grew only fifty-two lines and two-thirds. But the report 
of Abbe Nollet is not so favourable j he found that the plants electrified by him 
made vigorous shoots at the first, but he thought the perspiration being, by these 
means, too much increased, their juices were too quickly dissipated. Hence the 
plants became gradually weaker, and at length prematurely perished. We 
yield due credit to both these reports, though they seem in some measure incom¬ 
patible with each other. It is possible the experiments were made on various 
plants, at different seasons.— Col. Capper. — Mag. Gard. and Bot. 
General Management of Plants under Glass. —Alpine plants are such 
as will not grow to perfection in the open ground, and they must be protected 
during winter by a frame. They are mostly natives of high situations, among 
rocks, and on the tops of high mountains, and are consequently of low growth, 
will thrive well in a mixture of peat, loam and sand, the pots being always well 
drained with potsherds. They should be shifted, at least, twice every season, and 
be divided, if the plant has grown too large. The mould, which has been shaken 
from the pots, if not exhausted, must be mixed with new earth, and the plants 
potted afresh, after which they will require a little water. If these instructions 
be attended to, alpine plants will always look healthy and neat. 
Greenhouse Plants are such as are natives of the Canary Islands, New 
Holland, the Cape of Good Hope, and other countries in the same latitudes,
