CXXVIL PODOSTEMAOE. 

 1. MNIOPSIS, Mart. 



1. M HOOKERIANA, Tulasne Ann. Des. Sc. Nat. (3 ser.) xi, 

 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 the Concao, 

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

 only 1 to li 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 downw r ards ; flowers long-pedicelled. Concan rivers. Syn. 

 Mnianthus longipes, Wai. 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. 

 Rivers in Salsette, Law. This is a very distinct species, and most 

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

 Syn. Dalzellia foliosa, Wight Ic. 1919, fig. 2. 



4. LAWII. Rhizoma spreading, margins free, gemmiferous 

 leaves surrounding the sheath, few, short, broader than those 

 within, somewhat lanceolate, those of the sheath very numerous, 

 short, needle-shaped, recurved ; pedicels shortish ; capsule ovoid, 

 scarcely angled. Salsette, Law. Very distinct from the preceding 

 in the character of its leaves and sheaths. Syn. Dalzellia lawii, 

 Wight Ic. 1919, fiv.3. 



5. PEDUNCULOSA. Rhizoma spreading, margins free, lobed, 

 gemmiferous ; leaves all aggregated and united to form the sheath, 

 short bristle-like ; peduncle 6 to 8 times the length of the sheath, 

 very slender ; capsule ovoid, round or scarcely angled. Salsette, 

 Law. Syn. D pedunculosa, Wight Ic. 1919, fig. 4.
