the sepals, narrowly cuneate, apex rounded or shortly and irregu- 
larly bifid, glands absent ; ovary transversely oblong with slightly 
retuse base and apex, 2-celled, styles 2, filiform, exceeding the 
petals; male shortly stalked, sepals linear or cuneately oblong 
with rounded or irregularly dentate apex, succeeding internode 
shorter than the sepals; petals rudimentary, triangular ; stamens 
4, anthers black ; carpel-rudiments 2, shortly stalked, black. 
Plants 1 to 5 in. high, leaves 2 to 8 lines long by 3 line or less 
broad ; scapes from less than 1 in.'to 43 in.; sheath 3 to 10 lines; 
ripe flower-heads 1 to 2 lines in diameter ; involucral bracts 14 to 
2 line long by about } line or less in breadth ; floral bracts 3? line 
long and about half as broad ; sepals of female flower about 3 line 
each way, internode between sepals and petals nearly 4 line, 
petals 3 by 3 line; pedicel of male flower } line long; sepals 
scarcely } line; pedestal above sepals + line. The above measure- 
ments of bracts and flowers are taken from one of the larger 
full-grown heads. 
A very distinct species, 
Huitia.—In almost boggy wooded marsh-meadows growing very 
plentifully with Gentianaceze 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 Scytonema, 
plentiful along with a terrestrial species of Isoetes. Heads black. 
April and May 1860. No. 2449. A poor form. Occurs rather sparsely 
on the very lofty very short-grassed pastures of Empalanca, which are 
flooded in summer. Heads black or blackish. April 1860. No. 2450. 
2. E. longipetalum Rendle sp. nov. 
A dwarf plant with somewhat the habit of stunted forms of 
Juncus pygmeus; leaves numerous, rigidulous, very narrowly 
subulate, long-pointed, glabrous, surrounding and exceeding the 
numerous crowded scapes; scapes subcompressed, subquadrangular, 
shortly hairy at the base, exceeding the subacute or shortly bifid 
sheath which is closed for one-fourth its length and is also hairy 
at the base only; flower-heads bell-shaped, pale greenish-white, 
moneecious, few- often 10-flowered having a central male sur- 
rounded by females; receptacle truncated obconical, glabrous ; 
flowers dimerous ; involucral bracts slightly exceeding the disc, 
oblong, with a more or less oblique, truncate, or irregularly bifid 
often irregularly denticulate apex and a subtruncate base, gla- 
brous, lucent ; floral bracts of female flower similar but shorter ; 
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 wide 
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 bluntish apex, the shorter generally similar 
in form, sometimes very small, not exceeding the ovary, and 
lanceolate ; ovary broadly ovate, style dividing below the middle
