AM A RYLLIDACEjE. 
grow naturally in a sandy or strong soil on a dry rocky 
substratum, and proper rest has not been allowed them. They 
should be planted in light soil well drained, and be left dry 
from the moment their leaves show a disposition to wither, 
till the bulbs on examination show a disposition to push out 
fresh fibres at their base. The old fibres in this genus seem 
always to perish before the plant vegetates again ; it cannot 
therefore be injurious, and may be advantageous, to take the 
bulbs out of the ground when the leaves perish, and set them 
again when they are disposed to move. They will be best 
preserved while at rest in dry sand. Concerning the differ- 
ence between Pliycella and Habranthus, see the two first 
species of Habranthus, and the observations at the end of 
that genus. I consider that Phycellas should begin to grow 
in February and go to rest in August. If the leaf endures 
later than August, they should have six months rest before 
they are watered again. A sunny aspect at the foot of a 
south wall appears to suit them.

This genus must be erased, as not existing in truth ; the 
generic character being obscurely worded, and supported 
by a figure of the plant which I do not hesitate to pronounce 
fundamentally erroneous, both as to the extraordinary fila- 
ments there represented, and the pits in the tube under their 
point of insertion. I have no doubt that the plant intended 
was a Phycella, with appendages at the mouth of the tube, 
which have been incorrectly transferred to the mouth of the 
limb and fastened on the extremity of the filaments ; and the 
tube of the flower, injudiciously called in the text a pit, has 
been multiplied into six pits under the several filaments, 
where it is almost impossible that such cavities should be 
placed. If such had existed, they would have been between 
the filaments. I apprehend that the author must have for- 
gotten the precise intention of his own notes on the plant, 
and framed the figure from erroneous recollection drawn 
from his notes, and not from the plant itself, and I am con- 
fident that the representation given will never be verified.

of four lengths) inserted alike at the mouth of the
