and I think it will be found that like that plant it remains 
expanded at night and begins to close early the first morn- 
ing. The peduncle, and the less length of tube, which 
induced Dr. Graunam to refer it to a new Genus, are both 
variable features even in Zepuyrantues, which is the most 
nearly allied to it, Z. verecunda having sessile flowers, and 
tubispatha and Atamasco pedunculated ones. The non-ex- 
Fansion, which was the only other feature of difference noted 
by Dr. Granam, was, I suspect, owing to its not having 
been watched in the night time. The angular pollen 
observed by him is precisely that of Coorerta. I have 
also had the benefit of examining Mr. M‘Nas’s drawing, 
in which the tube is absolutely erect, and the limb almost 
white, agreeing with the specimen, which the figure in 
“ Sweet’s Flower Garden” does not. Mr. Don did not 
see the specimen, and formed his opinion of the plant from 
the figure, which has no dissection, and certainly not a very 
correct outline. Mr. M‘Nan’s drawing has precisely the 
same attitude of the tube as CooprriA Drummondi, both 
the tube and peduncle being quite erect. Cooperta 
Drummondi is a most variable flower. Three bulbs sent 
by Drummonp and supposed to be different, flowered at 
Spofforth ; one with the stigma between the anthers, one 
inclosed in the tube, one exceeding the anthers; but one 
of these bulbs, having sent up four successive scapes in 
about five months, exhibited all those diversities, and much 
variability of colour also ; so that C. chlorosolen can only 
be looked upon as a variety, and almost a variation of C. 
Drummondi. It is not improbable that this plant may have 
a like variable habit. C. Drummondi expands late in the 
afternoon, continues stellate all night, and begins to close 
for ever early the next morning, though it remains some 
time, and even days, in a half expanded state. The dis- 
section I have made from Dr. Granam’s specimen is pre- 
cisely double the natural size in all its parts.” W. H. 
The plant is a native of Texas, and was sent from thence 
in 1835 to this country. It has since flowered in several 
collections: firstly, at Dr. Netnx’s; also at Messrs. Dickson’s, 
from whose specimens the accompanying figure was made 
in March, 1836, at the Glasgow Botanic Garden, and at 
Mr. Herserr’s of Spofforth, who has kindly communicated 
some further information, in September, 1836. “It is,” 
he says, “ like the other Cooperiz, a decidedly nocturnal 
flower ; that is, its expansion takes place about an hour 
or half an hour before sunset. My flower did not expand 
perfectly
