32 HANDBOOK OF BRITISH HEPATIC^. 



flowers monogynous. Innovations sub-floral, soli- 

 tary, or binate and opposite, in most species 

 adnate to the bracts, in others absent. Bracts 

 one, rarely many jugate. Pedicel almost the same 

 as in Jubula ; axial cells 4-seriate, peripherical 

 i2-i6-seriate. Capsule with the inner face 

 spongy. 



The genus Lejeunia, as recognized by Spruce, 

 contains all the strictly monogynous Jubulece, and 

 is well distinguished from Frullania by (i) the 

 branches being contiguous to the outer base of 

 the leaves, i.e., infra-axillary ; (2) the usually 

 rhomboidal or ovate lobule being either plain or 

 ventricose, but never (as in Frullania} either 

 galeate or inversely saccate-shaped, like a bell, or 

 a glove finger except in the very rare case of 

 L. calyptrifolia, and three or four allied tropical 

 species, where the lobule is lengthened out into 

 the shape of a hollow horn or club ; (3) the mono- 

 gynous female flowers ; (4) the innovations, where 

 present, being adnate to the female bracts ; (5) the 

 pedicel cruciate on the section, only four cells 

 (not eight) across, quasi-articulate when dry, and 

 mostly geniculate at the joints. In addition to 

 the foregoing, Spruce also gives, in the work 

 already alluded to, valuable notes on the species 

 of Lejeunia, which are remarkably common in 

 tropical countries. For a local Flora it is wholly 

 unnecessary to follow him into his divisions of this 

 large tropical genus, into subgenera. Although 

 admitting Colura, and Phragmicoma, as subgenera 

 of Lejeunia, he also confesses that hereafter some 

 may consider them entitled to rank as genera, 

 with the residue of his temporary subgenera.
