﻿A new Species of Utricularia. 



By John Hendley Barnhart. 



Utricularia macrorhyncha. 



Stems white, fibrillous, rooting, utriculate : leaves few, capil- 

 lary, 2-20 mm. long ; scape one (rarely two arising from the same 

 point), slender, smooth, light green, 5-10 cm. high, with several 

 minute scales : flowers 1—3, usually 2 ; pedicels 6-18 mm. long, as- 

 cending in flower, erect in fruit : sepals ovate, 2 mm. long : corolla 

 yellow; upper lip concave, obscurely 3-lobed, 6 mm. long, 10 

 mm. wide ; lower lip concave (or with lateral margins slightly re- 

 flexed in age), entire or with merely undulate margin, 8 mm. long, 

 8 mm. wide, with a prominent orange somewhat 2-lobed palate 

 closing the throat ; spur slenderly conical, ascending, closely ap- 

 pressed against the under surface of the lower lip, which it ex- 

 ceeds in length (length 1 cm. or more), obtuse or emarginate at 

 the apex : fruit (immature) spherical. 



In mud, or rooting in water not over 5 cm. deep, in springy 

 places near the margin of a small lake, called by the northern set- 

 tlers in the neighborhood Mirror Lake, but better known among 

 the natives of the region as Calf Lake, Jessamine, Pasco County, 

 Florida, March 26 to April 1 1, 1898 ; distributed by me under no.

In habit, in stems and in leaves, this species resembles U. sub- 



idata L., with which it grows, but here the resemblance ceases, 

 for the flowers are entirely different, and the scapes of U. mac- 

 rorhyncha are light oreen and merelv slender, while those of U.

 the latter paper;]; but that species was a floating one, while U. 

 macrorhyncha roots firmly in the mud, although growing in situ- 

 ations favorable for a floating species. U. longirostris, too, is said
