AM A RYLLIDACEiE. 
The seed approaches to that of Crinum. Professor Lindley 
(Bot. Reg. 1219.) formerly expressed a doubt of the distinc- 
tion between Ammocharis and Nerine. It will be found, 
however, on examination that those two genera are very far 
removed from each other in natural affinity. The genus 
Nerine is distinguished by characters that cannot be misap- 
prehended, the gibbous monadelphous union of the filaments 
with the limb which has only an annular connexion. The 
nearest affinity of Ammocharis is unquestionably to Buphane; 
that of Nerine to Brunsvigia and Strumaria. The ovules of 
Nerine do not adhere like those of Ammocharis to an inter- 
mediate placenta. 
Bulbs of Ammocharis require complete rest in winter, 
when they must not be watered. They are exceedingly 
thirsty in summer, and if planted in light earth and left fora 
short time in the sun without water, the leaves will die back. 
It is essential, therefore, to supply them constantly with 
moisture. To make them flower the pot should be plunged, 
in the summer, in a hotbed after the leaves have grown to 
some length. In that situation it should be shaded from 
scorching sunshine, and it should not be kept longer than 
necessary in the hotbed. A rich and not very light soil is 
suitable to it in cultivation, and I have found it even succeed 
pretty well in peat ; but I have found the bulbs at all times 
liable to unexpected rottenness, from incautious watering. 
It does not seem possible to distinguish falcata fromCoranica 
by the bulb or leaf, yet there is sufficient diversity between 
their inflorescence to have induced Mr. Ker to place them in 
different, genera, though he was certainly mistaken in so 
doing. I have found the cells in falcata 6-8-seeded, in Cora- 
nica 15-16-seeded. The germen of Coranica has the same 
angles as falcata, but they are faintly marked, and on the 
peduncle they become almost obsolete. The difference be- 
tween them is perhaps sufficient to separate them as species, 
though it can be only seen in the blossoming. 
66. Crinum. — Germen thickest in the middle; tube cylin- 
drical, slender ; filaments inserted just outside the 
tube, more or less recurved ; anthers incumbent, ver- 
satile ; stigma 3-cornered or trifid ; capsule soft, de- 
formed, without valves or furrows ; dissepiments 
obsolete. Seeds very irregular in form, size, and 
number. (Leaves properly tubular at the base.)
