[Although the Utricularias are of neither medicinal nor technologic 

 value, yet they claim our interest as remarkably pretty plants, and 

 are by all coUectors gathered with predilection for the herbarium 

 particularly on account of their varied and offen remarkable structure. 

 They possess however particular pbysiologic interest, as for instance 

 it is now well ascertained that the niinute pitchers, with which some 

 species are so copiously provided, „entrap animalcules," and elaborate 

 vegetable pepsine for digesting them readily. No doubt they perform 

 much other work in the economy of nature. The genus is represented 

 in most parts of the globe ; sometimes however only by delicate 

 ephemerous annuals. Bentham and Hooker, in their great opus 

 , Genera Plantarum," rated in 1876 the number of species as high as 

 150, though as a niaximum only six can be distinguished in all Europe. 

 In the „Flora Australiensis* however twenty species became recorded 

 already in 1869, to which since three have been added, two of them 

 now for the first time characterised. 



Utricularia lasiocaulis. Root consisting of minute fibres ; leaves at 

 flowering time none; stem short, weak , very slender, simple, rather 

 densely beset with very short soft spreading hair; flowers one to four, 

 on terminal stalklets, from twice to several times as long as the 

 comparatively large coroUa, more or less downy or becoming glabi-es- 

 cent; bracts at the base of the stalklets short, ciliated, basifixed ; sepals 

 blunt, many times shorter than the purplish or violet-coloured corolla, 

 the lower sometimes cleft at the end into two short lobes; upper lip 

 of the coi'olla rhomboid, or cuneate, or bieular; lower lip slightly 

 longer, offen broader than its own lamiual length , wavy, but not 

 distmctly lobed ; spur somewhat longer than the lips, or about as long, 

 descending, cylindric-conical, gradually attenuated, but not very acute. 



Near Port Darwin; Maurice Holtze. 



The specimens seen by me a few inches high; stalklets reaching 

 two inches in length; width of the lower coroUa-lip nearly half an 

 inch ; spur alniost as long ; fruit not obtained. 



No other species from Australia is extensively downy; in this respect 

 it approaches U. hirta, but diff'ers from that species already in the 

 very elongated stalklets, in broader bracts, in the much larger corolla 

 with down-bent spur; the fruit in all likelihood will also prove very 

 different, particularly as the seeds of many of the species exhibit such 

 marked characteristics. 



Utricularia leptopiectra. — Root short, fibrous; leaves at flowering 

 time none; stems rather long but very slender, glabi-ous; flowers few, 

 terminating singly distant long alniost capillary branches or stalka ; 

 bracts centri-fixed, acutely pointed, particularly at the upper extreniity; 

 stalklets hairiike-thm , shorter than the rather large flower; sepals 

 roundish, several times shorter than the blue corolla; lower lip very 

 much longer than the upper , bifid , with oblique cuneate-semiovate
