13. U. dichotoma, LahilL PL Nov, Hull i. 11. /. 8. Scapes slender, 

 from a few inches to above 1 ft. higli. Leaves radical, petiolate, from almost 

 ovate and 1 line long to linear or oblong, 3 to 4 lines long (or in a few ab- 

 tiormal speeimeus more than 1 in. and very narrow), accompanied by filiform 

 fibres, some of them bearing small fringed utricles, the leaves sometimes dis- 

 appearing before the flowering. Flowers purple or lilac, opposite in 1 or 2 

 pairs or whorls of 3 at the end of the stem, rarely reduced to a single termi- 

 nal flower. Pedicels filiform, at first very short but lengthening to from \ to 

 \ in. under the fruit. Bracts always opposite or in threes (even when the 

 flower is solitary), small and narrow, very shortly produced below their in- 

 sertion. Calyx-segmeni;:, usually about \\ lines long, broad and obtuse. 

 Corolla : upper lip small, broadly ovate or obovate, obtuse or obscurely 2- 

 lobed ; lower lip horizontal, broadly senn'circular, | to f in. across, the palate 

 ^Hth a small 3-lubed prominence ; spur descending, obtuse, much shorter than 

 tlie lower lip and sometimes very short. Capsule membranous. Seeds 

 small, ovoid.— A. DC. Prod. viii. 14 ; Hook. f. 11. Tasm. i. 290 ; F. Muell.

 i^C. Prod. viii. U; Hook. f. Fl. Tasm. i. 299. Gerieially mixed with the 2- or niore- 

 fipwercd specimens, but chiefly in N. S. Wales. The specimens distinguished by Brown as 

 013 three species appear to me to differ only in the number and size of the flowers, which arc 

 always variable in all the sets of U. dichofoma which I have seen. 



U. IT. volubilis, R. Br. Prod, 430. Scapes rather slender, twining 

 sometimes to the leno-th of 3 ft. or more, with a radical tuft of filaments, some 

 of them bearing rather large utricles (often 2 lines diameter), but no leaves 

 seen. Flowers lar-e, purple, opposite in one or two pairs or rarely reduced 

 *« a single tennimil flower. Pedicels \ to 1 in. Bracts opposite, narrow, 

 Pi-oduced below their insertion into an appendage sometunes nearly as long 

 f tbe upper part. Calyx-segments thin, coloured, very obtuse, nearly 2 hnes. 

 'o^g. Corolla: upper lip scarcely twice as long as the calyx, broadly ob- 

 ^^ate or almost orbicular, retuse ; lower lip horizontal, senucircular, entire 

 ?^o 1 in. across, the palate yellowish, with a small 3-lobed protuberance at 

 fs base ; spur descendinir, short and verv obtuse.— A. DC. Prod. via. 14,
