G6 PODOSTEMONACEJE. (J. D. Hooker.) [Podostemoj?. 



smooth. Mniopsis Hookeriana, Tul. in Ann. Sc. Nat. Ser. 3, xi. 104, and 

 Honogr. Pmloxt. 147, t. 8, f. 5; Wight Ic. t. 1918, f. 4. 



The COXCAN ; near Bombay, in streams, Law. N. CANARA, in the Kala nuddi, 

 Talbot. 



Plant 1-2 in. broad, appressed to rocks, &c. Leaves not keeled, lower short obtuse, 

 upper in. long. Spathe tubular, mouth 2-lobed. Pedicel about in. Filfiin^nt 

 flat; staminodes linear, acute, shorter than the ovary. Ovary sessile, globose ; stigmas 

 long, subulate-lanceolate. Capsule subglobose, one valve falling away before the 

 other. Mr. Hemsley regards the Canara specimens as intermediate between P. stylosus 

 tmd algceformis. 



7. P. Johnsonii, Wedd. in DC. Prodr. xvii. 75 ; plant an irregularly 

 dilated membranous suborbicular or lobed frond, buds on the upper surface 

 1-fld. of 4-6 distichously imbricate ovate obtuse keeled leaves,, capsule 

 smooth or with 8 confluent broad ribs. Mniopsis Johnsonii, Wight Ic. 

 t. 1919, f. 5. 



MALABAB ; in rivers, Johnson. 



Plant 1-1 in. broad, appressed to the stones, &c. Leaves ^ in., spreading, rigid 

 when. dry, upper rather the longest. Spathe ovoid, subcompressed, split ventrally and 

 at the tip. Filament longer than the ovary ; anthers ovate ; staminodes very narrow, 

 incurved above, equalling the ovary. Ovary globose, sessile; stigmas short, linear. 

 Capsule ellipsoid. 



8. P. olivaceus, Gardn. in Calc.Journ. Nat. Hist. 181 ; plant a mem- 

 branous irregularly lobed flat frond, buds crowded on its upper surface 1-fld. 

 of 6 equitant oblong obtuse acutely keeled leaves, capsule with 8 thick ribs. 

 Wedd. in DC. Prodr. xvii. 75. P. griseus, Gardn. 1. c. Hydrobryum oliva- 

 ceum & griseum, Tul. in" Ann. Sc. Nat. Ser. 3, xi. 104 and Monogr. Podost. 

 138, 140, t. 9 ; Wight Ic. 1. 1918, f. 2. ? P. Gardneri, Harv. mss. ; Thwaites 

 Enutn. 223. 



KILGHIEI MTS. ; in the Pycarrah River, Wight. CEYLON ; in the Mahawalle 

 Gunga River, Gardner, &c. 



Plant about 1 in. broad, apprised to rocks, &c., its lobe's sometimes imbricating. 

 Leaves ^ in., upper larger. Spathe elliptic-oblong, incumbent on the frond, at length 

 split longitudinally. Pedicel at length in. long. Filament compressed, arms short, 

 anthers ovate ; stamiuodes linear, shorter than the ovary. Ovary sessile ; stigmas 

 short, triangular-lanceolate. Capsule ellipsoid, ribs of the persistent valve decurrent 

 on the pedicel. P. Gardneri, which consists of a simple terete stem crowned with 

 capillary leaves, and grows on the rootstock of P. olivaceus, is supposed to be an 

 abnormal foliaceous development of that plant. 



9. P. a cumin at us, Wedd. in DC. Prodr. xviii. 75; plant a flat 

 frond radiately lobed, buds in the sinus and. angles between the lobes 1-fld. 

 of 6 equitant leaves terminating in long subulate caducous points, cap- 

 sule broadly 8-ribbed. 



KHASIA MT$., in the Bogapaue and Kalapane Rivers, J. D. H. Sf T. T. 



Plant minute, membranous, subdichotomously irregularly shortly forked or lobed 

 and toothed. Buds horizontal; lower leaves shorter, obtuse. Spathe ellipsoid, nar- 

 rowed below, at length split longitudinally. Pedicel ascending, ^ in. Filament 

 flattened, arms short, spreading, staminodes linear, half as long as the ovary. Stigmas 

 subulate-lanceolate. Capsule obliquely ellipsoid, ribs of the persistent valve decur- 

 rent on the pedicel. 



10. P. mlcrocarpus, Wedd. in DC. Prodr. xvii. 76; plant a dicho- 

 tomous flat branching frond bearing scattered 1-fld. buds of 6-8 equitant 

 subacute compressed keeled leaves, spathe boat-shaped, capsule obovoid
