completely excreted by the anthers, had coalesced into 
masses definite both in number and form, and these had 
been taken up by appropriate processes of the pistils. Viewed 
thus in their final station on the stigma, these bodies were 
_ by some observers held to be the stamens of a gynandrous 
a 
flower, while the remainder of the stamineous structure was 
left unaccounted for. By others, who combined with the 
view of those parts that of the natural. relation of thé 
parent-plant to the rest of the vegetable system, and. drew 
their conclusion in part from analogy, the same bodies 
were surmised to be the distinct secretions of the cells of 
the five bilocular anthers of as many stamens of a pen- 
tandrous flower; and both their formation‘and station to be 
secondary. A supposition which has been recently reduced 
to certain knowledge, and the structure and economy of 
these parts ascertained by Mr. Brown in a series of observa- 
tions made at much earlier stages of their formation than it 
had occurred to others to observe them in. oie 
Catorropis consists of but one species besides the pre- 
sent, which is a tall upright plant, sometimes acquiring 
the height of 6 or 8 feet, covered, unless at the corolla, by 
a soft white deciduous down; leafless, except towards the 
upper part, producing throughout a thick milk-coloured 
juice, which presents itself on the slightest puncture. 
Corolla purplish white, with five vertical prominent com- 
pressed appendages, fixed at equal-distances along the out- 
side of the stamineous tube, resembling so many diminutive 
porcelane handles, or brackets. pre ad 
These are the nectaries of Linneus; are partly. hollow 
‘and partly solid, but contain no liquid as far as we observed ; 
and of the share they bear beyond ornament, in the economy 
‘of the plant, nothing seems to be known.
