Tribe 11. JUNGEliMANlEyE. 



Eamification various, lateral or partly postical (floial branches 

 principally) ; rarely all postical, very rarely antical. Leaves iti- 

 cubous, transverse or succubous, alternate or opposite ; very 

 various in form, subexplanate or concave, entire or very often 

 divided, but very rarely complicato-bilobate. Stipules in some 

 genera constantly present, in others very rare or absent. Flowers 

 ? in some always monandrous, in others oligandrous, in very 

 few polyandrous. Flowers <? oligo-polygynous ; pistillidia 5-80, 

 free, or when in fruit more or less adnate to the calyptra. 

 Perianth very variable; complanate, trigonous or polygonous, 

 rarely perfectly terete, mouth wide or constricted ; sometimes 

 really or apparently absent, in a few species forming a fleshy 

 pendulous pouch. Calyptra usually free, in some species adnate 

 to the perianth or involucre. Capsule globose, oblong or cylin- 

 drical, quadrivalvate to the base, dehiscing irregularly in very few 

 species. Elaters in almost all cases dispiral, rarely monospiral or 

 3-4-spiral, deciduous ; sometimes a few heteromorphous elaters 

 persist a little longer than the rest either at the base or the apex 

 of the capsule, but finally fall away in the same manner as the 

 normal ones. 



A. Elaters normally dispiral. 



a. Iiadioles arising from tlie lobule of the leaves. 



Subtribe I. RADULE.E. 



Plants rather large, prostrate, dichotomous or laxly pinnate. 

 Branches all lateral, infra-axillary. Loaves incubous, complicato- 

 bilobate, the inferior lobule smaller, radiculose. Stipules none. 

 Flowers 3 1-3-androus. Perianth almost always frontally com- 

 pressed, sometimes complanate, with a wide truncate mouth. 

 Capsule in almost every instance oblongo-cylindrical. 



b. Radicles arising from the stem or Ironi the postical 

 stipules.
