 4, anthers black ; carpel-rudiments 2, shortly stalked, black. 



Plants 1 to 5 in. high, leaves 2 to 8 lines long by -^ line or less 

 broad; scapes from less than 1 in.ito 4^ in. ; sheath 3 to 10 lines; 

 I'ipe flower-heads 1 to 2 lines in diameter ; involucral bracts 1^ to 

 '4^ line long by about i line or less in breadth ; floral bracts ^ line 

 long and about half as broad ; sepals of female flower about ^ line 

 each way, internode between sepals and petals nearly ^ line, 

 petals ^ by ^ line ; pedicel of male flower ^ line long ; sepals 

 .scarcely \ line ; pedestal above sepals i line. The above measure-

 full-grown heads. 



A very distinct species. 



HuiLLA. — In almost boggy wooded marsh-meadows growing very 

 plentifully with Gentianacese and species of Drosera between Lopollo 

 and Monino. Heads very black. March, April, and May 1860. 

 No. 2448. Various forms differing in age and size of head. On boggy 

 shortly grassed slopes densely packed with species of Srt/tnnemd, 

 plentiful along with a terrestrial species of Ixoete^. Heads black. 

 April and May 1860. No. 2449. A poor form. Occurs ratlier sparsely 

 on the very lofty very sbort-grassed pastures of Empalanca, which are

2. E. longipetalum Rendle sp. nov. 



A dw^arf plant Avith somewhat the habit of stunted forms of 

 Juncus pygm(eus ; leaves numerous, rigidulous, very narrowly 

 subulate, long-pointed, glabrous, surrounding and exceeding the 

 numerous crowded scapes; scapes subcom pressed, subquadrangular, 

 shortly hairy at the base, exceeding the subacute or shortly bifld 

 sheath which is closed for one-fourth its length and is also hairy 

 at the base only; flower-heads bell-shaped, pale greenish-white,

 flower sessile, lyre-shaped ; sepals glabrous, sometimes slightly 

 unequal, boat-shaped, keeled, linear-falcate, tapering shortly to an 

 acute, subacute or obtuse minutely denticulate apex, keel as wdde 

 as the side of the sepal, narrowing above and below, edge slightly 

 uneven ; petals glabrous, very unequal, the longer strap-shaped, 

 projecting laterally from the top of the flower, twisting at the 

 middle, with erose or bhmtish apex, the shorter generally similar
