444 UTRICULARIA MULTICAULIS. Chap. XVIII. 



project straight forward ; they are united for a short 

 space at their bases by a membrane ; and they bear a 

 moderate number of bristles or hairs, not simple as 

 heretofore, but surmounted by glands. The bladders 

 also differ remarkably from those of the j)revious species, 

 as within there are no quadrifid, only bifid, processes. 

 In one bladder there was a minute aquatic larva; 

 in another the remains of some articulate animal ; 

 and in most of them grains of sand. 



UtriculariOf cserulea (India). — The bladders re- 

 semble those of the last species, both in the general 

 character of the antennae and in the processes with- 

 in being exclusively bifid. They contained remnants 

 of entomostracan crustaceans. 



Vtricularia orhiculata (India). — The orbicular leaves 

 and the stems bearing the bladders apparently float in 

 water. The bladders do not differ much from those of 

 the two last species. The antennae, which are united 

 for a short distance at their bases, bear on their outer 

 surfaces and summits numerous, long, multicellular 

 hairs, surmounted by glands. The processes wdthin 

 the bladders are quadrifid, with the four diverging 

 arms of equal length. The prey which they had 

 captured consisted of entomostracan crustaceans. 



Utrieularia multicaulis (Sikkim, India, 7000 to 

 11,000 feet). — The bladders, attached to rhizomes, 

 are remarkable from the structure of the antennae. 

 These are broad, flattened, and of large size; they 

 bear on their margins multicellular hairs, surmounted 

 by glands. Their bases are united into a single, 

 rather narrow pedicel, and they thus ap]3ear like a 

 great digitate expansion at one end of the bladder. 

 Internally the quadrifid processes have divergent arms 

 of equal length. The bladders contained remnants of 

 articulate animals.
