 104. — A minute plant, moss-like, with the stems densely leafy and 

 cespitose, and a frond beneath like a lichen, creeping on stones in 

 running water ; flowers terminal, solitary, or sometimes a little 

 branched, having one forked filament, each division bearing a 

 perfect anther ; capsule spherical, smooth, 2-celled, surmounted by 

 2 stigmas. Common in the running streams of tlie Concan, 

 flowering as soon as its head is above water ; the whole plant is 

 only 1 to 1 J inch high. Wight Ic. 1918, fig. 4. 



2. TERN I OLA, Tulasne. 



1. T PuLCHELLA, Tulasne Monogr. Podostem. p 189. — Rhi- 

 zome thin-linear, branched, short ; flower bearing here and there 

 'leaves linear, marked with a whitish line in the middle, distichous, 

 interior ones the flower-bearing bud, verticelled and united at the 

 base; pedicel of middling length. Concan rivers. Syn. Lawia 

 pulchella, Tulasne; Mnianthus pulchellus, Walpers. 



2. T LoNGiPEs, Tul. loc. cit. — Rhizome thin, broadly linear, 

 sparingly branched ; leaves long-linear acute, marked with a whitish 

 line, near to the flower inserted in a circle, and at the same time 

 united downwards ; flowers long-pedicelled. Concan rivers. Syn. 

 Mnianthus longipes, Wal. Ann. iii, 443. 



3. FoLiosA. — Rhizoma spreading lichen-like, lobed and free on 

 the margin ; buds for the most part on the free margin ; leaves 

 numerous fascicled, round at base of the pedicel, long, linear- 

 pointed, no sheath ; pedicel 2 to 3 times the length of the leaves.

 easily recognised by its tufts of well-formed leaves, and no sheath.
