turbinate, marked by ten longitudinal, spirally twisted ribs, densely 
hispid; limb consisting of five broadly linear foliaceous divisions, 
marked on each side with one or two teeth. PrTats five, inserted 
between the lobes of the calyx, of a brick-red colour, hood-shaped, 
hairy on the outside. Sauam# five, opposite the divisions of the 
calyx, about a third the length of the petals, green, concave, three- 
ribbed, truncate at the top, and each dorsal rib terminating in a short 
brown blunt point. STameEns arranged in five bundles, placed oppo- 
site, and almost inclosed within, the petals; each bundle consisting of 
about fifteen stamens, which are nearly as long as petals: within each 
Squama are also two filaments, thick and expanded at the base, pro- 
jecting far beyond the squamz, connivent round the stigma, tapering 
and slightly pubescent towards the extremity, which terminates in a 
minute orange point, usually hooked. Ovary included within the 
tube of the calyx, one-celled, terminating in a broad, flat, spreading 
disk, with five roundish green hairy lobes, alternating with the stamens 
and petals. Styxe thick, cylindrical. Stiamas three, occasionally 
four or five, linear, decurrent nearly half way down the style. Pta- 
CENT three, extending the whole length of the ovarium, linear, 
attached by the back, the margins free, each bearing a very great 
number of ovules; sometimes where there are four or five styles, there 
is also a fourth or fifth placenta, extending a short way down the 
arium. CapsuLs nearly cylindrical, slightly swollen in the middle, 
much twisted, two to three inches long. Srxps opening by longitu- 
dinal slits along the centre of each placenta, each half of which 
remains attached to the margin of the valve. SEEDS numerous, 
tuberculated. 
PopuLar AND GEoGRAPHICAL Novice. The Order of Loasacer, 
to which this genus belongs, is almost exclusively American, there be- 
ing only on2 or two species known in the old world from South West 
Africa, Three species only were known to Limneus, and it now consists 
of about twelve genera and nearly one hundred species, growing chiefly 
in the mountainous districts of both portions of the American conti- 
ent, from = sapien to — Chile, and from the Pacific eastward as _ 
great chainextend. They forma perfectly dis- 
tinet order among the rte Calyciflore, readily known amongst 
allied groups as well by their habit as by characters easily appreciated. 
Their first and most obvious affinity is with Cucurbitacez, with 
which the tendency to a climbing habit, the rigid hairs and as 
of their leaves and stem, as well as the inflorescence and Re Re of 
the flowers, give them a general similarity in appearance, confirmed 
by the adhering calyx, unilocular ovarium, parietal placente, and the 
quinary arrangement of the floral envelopes, usually combined with a
