OF tTTRTCULATlIA FROM SOUTH AMERICA. 171 



No. 194. Vtricularia pallens, St. Hilaire. Para coll. 



No. 444. „ „ „ Santarem. 



No. 1071. U, Parkerianal, 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.

Seeds about 20-24, flattened, peltate, girt with an obtusely polygonal, 

 narrow, submembranaceous wing. 1 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. injiata, Walt., of the North American 

 continent. Specimens from Florida (Rugel, coll.), labelled U. injiata, 

 var. minor, do not seem different.

No. 2986. San Carlos. U, longeciliata, A. DC. (Prodr. viii. p. 23). 

 Polypompholyx laciniata, Benjamin (in Linnaea, xx. pp. 316, 496, and 

 Flor. Bras. Utricularice, p. 251). 



Collected also by Grardner, Hostmann, and others in Brazil and 

 Guiana. Benjamin errs in referring this plant to the Australian 

 genus Folypompholyx, established by Lehmann (Nov. stirp. Pugill. 

 viii. p. 48), the Tetralohus of A. DeCandoUe (Prodr. viii. p. 667). 

 The calyx of TTtricularia is constantly diphyllous. In the true 

 FolyjpompJiolyx, in addition to the anterior and posterior calycine 

 segments, common also to Vtricularia, 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 Vtricularia. 



In TI. longeciliata the lateral bracteoles, which are rather largely
