THE AMARYLLIDiE. 
the green-house ; all the other species must be potted in very sandy 
loam, with a small portion of peat and leaf-mould, and placed like 
the two last in the green-house. The Z. Candida closes its flowers 
in the evening, or if placed in the shade, after the manner of the 
crocus. 
16. Habranthus, {Habros delicate, anthos flower.) All the flow- 
ers of this genus are very delicate, the H. versicolor and gracilifor- 
mis very fragrant, they may be planted out in light rich mould, on 
any warm border, and if covered in severe or very wet weather in 
winter, with an inverted flower pot, the bulbs will be preserved 
from perishing, and will flower very freely ; the H. bifidus, rosea, 
Bagnoldi, and Phycelloides, will all thrive well if planted in a bor- 
der, in the front of a stove or green-house ; let the bulbs be well co- 
vered in winter, to keep them from being injured by frost or wet : 
the H. Andersoni, lorifolius, angustus, and spathaceus, all require 
the green-house, and should be ti-eated exactly like the Amaryllis, 
and other green-house bulbs in this order. They are all increased 
by oflsets, and occasionally by seeds, which, however they very sel- 
dom ripen. 
17. Doryanthes, {Dory, spear, anthe, flower; stem.) This genus 
contains but one species, the D. excelsa, it diffefs materially from 
all the preceding genera, the flower stem growing to upwards of 
twenty feet high, it grows freely in a mixture of sandy loam, peat, 
and well rotted leaf-mould, and should be placed in the conservatory. 
It may be increased by suckers from the roots, which are sparingly 
produced. 
18. Gethy'llis, {Getheo to rejoice ; perfume of flowers.) All the 
species are gi-een-house plants, natives of the Cape, and should be 
potted in sandy loam and peat, " the berries of the G. afra are said 
to be eatable, having an agreeable odour," they require the usual 
treatment with regard to watering, &c. as the other Cape Ama- 
ryllidae ; they are increased by oflfsets and seeds. 
19. Alstroemeria, {Baron C. Alstrcemer, a Swed. Bot.) The 
roots of all the species of this splendid genus, abound in a nutritive 
fcecula which may be prepared for food, the natives of Chili obtain 
from the roots of one of the species, a substance resembling arrow- 
root. They will thrive if planted in a mixture of about equal parts 
of rich loam, sand, and leaf-mould. A hirtella, and ovata, do very 
well on a warm border, and the former will ripen seeds very freely, 
which as soon as ripe should be gathered and sown in pots, and the 
young plants turned into the borders in the following spring. Al- 
though the Flos Martini, pulchella or Hookeri, Simsii, Salsilla, &c.
