Difference of Structure in the Flowers of fix Species of Paffiflora. 27 
{ 
Paffiflora minima. Linn. Tas. 5, fig. f. 
This has been fuppofed the fmalleft of the tribe, whence its name, 
though there are others nearly if not quite as fmall: it is how- 
ever very pleafing to fee how perfect the parts of fructification are, 
and how nearly they refemble each other, infomuch that the fpe- 
cies fecm not yet perfectly diftinguifhed; though I prefume, when 
carefully exaniined, they will be as diftinguifhable as the guadrangu- 
lari; and alata. Y have not feen many; but among what I have feen, 
they are in a fimilar predicament with regard to the ftalk and fo- 
liage. In this I have fome reafon to think that the ruffle under 
tlie germ (ro) will mákeit diftinét, and perhaps the fringed edge of - 
the operculum may affift: in other refpeéts two or three fpecies of 
the fmall forts feem to be exactly the fame, or not to be eafily known 
from each other. I fhould have obferved, that they are many of 
them deftitute of the involucrum, in thofe that I have feen, though 
there is a joint between the peduncle and pedicle where we fhould 
naturally expect it: they alfo have but five petals, confequently 
have not any thing that ferves as a calyx: but to proceed to the 
nectaries, &c. 
I. Peduncle Cylindrical. 
2. Involucrum ' None. 
3. Pedicle Cylindrical, curved a little, thickeft at 
the flat bafe of the flower. 
A. Petals Five, lanceolate, turned back. 
5. Principal rays Cylindrical, fpreading, curved back. 
6. Imperfeét rays Moftly clubbed, fometimes bifid. 
7. imperfect operculum None. | 
8. Operculum Plaited and fringed at the edge. 
9. Neétary The fame as the laft, except thatat the 
ridge of the protuberating bank are 
fome fmall, regular, roundiíh glands, 
or imperfect rays, if I may fo call them.
