CL. XXIV.] 39. JUNGERMAXIA TRILOBATA. 455 



membranaceous, cylindrical, deeply notclied calyx springs 

 from the axillae of the lower part of the stem, (by no means 

 from the top, as Roth maintains.) The fruit-stalk is tender, 

 white, pellucid, erect, smooth, about the size of a fine linen 

 thread. It carries a brownish-red capsule, which at first is 

 closed like a splendent sphere ; afterwards it opens with four 

 valves, which stand cruciform from one another, and have 

 the seeds hanging by a chain-shaped appendage. 



Diagnosis and Affinity. 



The species most nearly related to this are J. Florhii Web. 

 Mohr. and Naumanni Nees. But the former is distin- 

 guished by sending out tendrils only below the stern, by 

 having its leaves not so much lengthened, and rather verti- 

 cal, and chiefiy by the size and multifarious division of the 

 amphigastri^, (Mart Fl. Crypt. Erlang. p. 144. t. 4. f. 17.) 

 J. Naumanni has still shorter leave;, placed still more re- 

 mote from each other, and deeply divided, ciliated araphi- 

 gastriae, (Mart. 143. 4. f. 16.) J. quinque-dentata L. is very 

 like our species, but it wants the amphigastriae, and the leaves 

 are much shorter. J. nitida {co7ivexa Thupb,) is distin^ 

 guishes by its uniform, quadri-partite amphigastrifs, the la- 

 ciniae of which are subulate. There is a smaller variety, 

 v/hich passes into that of Roth, and the amphigastrlge of which 

 are merely crenated : This is J. tricrenata VVahlenb. Car- 

 path, p. 864.
