OF UTRICULARIA FROM SOUTH AMERICA. 171 
No. 194. Utricularia pallens, St. Hilaire. Para coll. 
No. 444. » » » Santarem. 
No. 1071. U. Parkeriana?, A. DC. Santarem. This plant is allied to 
the foregoing, but differs in its longer, cylindrico-subulate, adpressed, 
obtuse spur which exceeds the lower lip of the corolla. The speci- 
mens are scarcely in a condition to be determined without doubt. 
No. 310. Santarem. 
No. 963. South shore of Amazon. | U. foliosa, L. 
No. 1611. Manaquiry. 
Seeds about 20-24, flattened, peltate, girt with an obtusely polygonal, 
narrow, submembranaceous wing. I take U. oligosperma, St. Hil., to 
be the same species, as also the U. vulgaris figured in Flor. Flum. 
(tab. 44), and quoted by St. Hilaire and Girard (Monog. Prim. et 
Lent. p. 21) as representing their plant. Are not these forms of our 
U. vulgaris, L.? 
No. 1053. U. quinqueradiata (Spruce's MSS.). Santarem.—I regard 
this as a small form of the U. inflata, Walt., of the North American 
continent. Specimens from Florida (Rugel, coll.), labelled U. inflata, 
var. minor, do not seem different. 
No. 10412. An U. purpurece, Walt., varietas? U. myriocista ?, St. Hil. 
Santarem.—Corolle albz (margine purpurascente) labium superius 
rotundatum integrum, 1. inferius amplum trilobatum lobis obtusis- 
simis, calcar conico-cylindricum obtusum quam labium parum bre- 
vius. U. palatina, Web. MSS. (in Hb. Hook. vidi) ad eandem 
accedit. 
No. 1044. Santarem, and 
No. 2986. San Carlos. U. longeciliata, A. DC. (Prodr. viii. p. 23). 
Polypompholyz laciniata, Benjamin (in Linnea, xx. pp. 316, 496, and 
Flor. Bras. Utricularie, p. 251). 
Collected also by Gardner, Hostmann, and others in Brazil and 
Guiana. Benjamin errs in referring this plant to the Australian 
genus Polypompholyz, established by Lehmann (Nov. stirp. Pugill. 
viii. p. 48), the Tetralobus of A. DeCandolle (Prodr. viii. p. 667). 
The calyx of Utricularia is constantly diphyllous. In the true 
Polypompholyx, in addition to the anterior and posterior calycine 
segments, common also to Utricularia, we find a pair of opposite, 
lateral and somewhat smaller lobes within the former. Minute 
lateral bracteoles with the usual subtending bract, as in numerous 
Species of the allied genus, are also found at the base of the 
pedicel. It is upon the quadripartite calyx alone that the genus 
depends; in other respects it is, I believe, quite a Utricularia. 
In U. longeciliata the lateral bracteoles, which are rather largely
