A curious species of Passion-flower, described, we be- 
lieve, only in the very useful work above quoted, where it is 
erroneously marked asa shrub. It was raised, from seeds — 
sent to this country by Professor Treviranus, at Mr. Colyill’s 
nursery, Where our drawing was made last August. 
A little annual plant, producing its flowers in two 
months after being sown, and ripening its seeds readily. Its 
native country is uncertain. 
With P. hirsuta, gracilis, augustifolia, suberosa, minima, 
peltata, and some others, it forms a very natural assemblage; 
remarkable for the absence of petals, and for the general 
minuteness of the parts of fructification. 
Stems slender, round, quite smooth, as is every part of 
the plant. Leaves on long stalks, cordate, three-Icbed; the 
lobes rounded, and having two glands; the middle lobe 
generally blunted. lowers solitary, pale green, shorter 
than the leaves. Culyz flat, rotate, 5-parted; the segments 
spreading, from a broad base lanceolate, channelled, longer 
than the ray. Petals O. Ray many leayed, in a single row,
