1 48 HalorageCB. \Myriofihyllum. 



numerous, close, usually alt., articulated with stem and leaving 

 a prominent scar, usually narrowly linear, acute, entire or 

 with a few large sharp teeth in upper part, glabrous, some- 

 times cuneate-obovate, with minute teeth and ciliate; ped. of 

 male fl. not longer than 1., very slender, glabrous ; fruit minute, 

 oblong-oval, narrowed above, glabrous, strongly 8-ribbed, 

 with the ribs tuberculated. 



Var. /3, minor, Clarke in Fl. B. Ind. 1. c. 



A minute plant, i|— 3 in., with filiform stems, 1. opposite, 

 very small. 



Upper montane zone ; very rare. On Adam's Peak, where it is abun- 

 dant near the base of the uppermost cone ; Maturata. Var. j3, Watte- 

 kelle, 1864. Fl. March, &c. 



Endemic. 



Thwaites did not distinguish this from the next, and called the com- 

 bined plants S. indica; and this is perhaps the best treatment. C. P. 

 451, with the fruit oi S. zeylanica, has the leaves of S. hirsuta, and looks 

 quite intermediate ; var. (3 seems to be merely a dwarf state of this form.

Stems prostrate, wide-creeping, often very long, much 

 branched, rooting at the nodes, slender, slightly pilose, red ; 1. 

 numerous, opp. or alt., nearly sessile, usually under \ in., 

 tapering to cuneate base, oval or obovate-oval, with a few 

 large teeth in upper half, glabrous on both sides, ciliate on 

 margin, often red beneath ; male fl. few, on very slender, 

 pubescent ped. longer than 1. (^-| in.), fern. fl. sessile, in 

 axillary clusters; male fl.: — cal.-segm. acute, pet. oblong, 

 concave, pubescent outside, soon falling, anth. large, cream- 

 coloured ; fern, fl.: — cal.-segm. triangular, pubescent, stigmas 

 spreading ; fruit very minute, broadly ovoid or subglobular, 

 not ribbed, pubescent. 



Moist open ground, especially near streams in the montane zone above 

 4000 ft. ; very common. Fl. all the year ; pinkish. 



Also in the mountains of S. India. 



As S. hirsuta and S. brevipes of Wight and Arnott are not distinguish- 

 able as species, and as the names are of the same date, I adopt that most 

 suitable to our form.
