СУРЕКАСЕЖ IN THE WELWITSCH HERBARIUM. 147 
Huilla, in pascuis macris breviter dumetosis prope Lopollo, Feb. et init. April. 1860, 
no. 6809, in pratis sylvaticis ad flumen Cacolovar, frequens, no. 6810. 
This plant varies very much in habit. The most striking forms are no. 6800, a 
strict erect plant, almost leafless, with a rather thick rhizome and very patent involucral 
leaves, which give it much the appearance of К. obtusata, Presl, and по. 6808, a very 
slender form, with long and narrow leaves, small capitula, and reflexed involucral leaves. 
The species is abundant also in Madagascar, and a variety occurs in the N eilgherries.

triquetris preesertim versus apicem, canalieulatis; foliis flaccidis anguste linearibus 
culmo brevioribus; capitulo singulo, ovato, ssepe altero minore laterali; foliis invo-

squamis navicularibus carinatis, carina viridi ciliata, lateribus pallidis purpureo- 
punctatis; squama inferiore 8-nervata, suprema 4-nervata, mucronata, mucrone

Pungo Andongo, ad margines fluminis Cuanza, prope Calemba, Mart. 1857, no. 6779, 
inter Lombe et Muta Lueala, 1856. 
This plant has a close affinity with Ж. alata, Nees, but is entirely glabrous ; the leaves 
are also narrower. The involucral leaves attain a length of 2 inches; the culm is from 
4 to 10 inches in height ; the caryopsis, which is not quite mature, is $ line in length.

carinatis, carina marginibusque apicum scabridis; vaginis integris purpureo-punc- 
tatis; involucralibus 3-4, uno erecto biunciali, altero breviore patente, linearibus 
acuminatis basi haud dilatatis, marginibus carinaque apicum scabridis; spiculis 
in capitulo perpaucis, triglumibus, basi squama ovata parva munitis ; rhachide haud
