224 DR. J. D. HOOKER ON THE PLANTS 
Also an Abyssinian and Madagascar plant, very near C. For- 
skahlii, if not the same; butinthe present condition of the genus 
Commelyna it is hopeless to identify a species in all its forms with- 
out a study of the whole. 
2. CvANoTIS ABYSSINICA, A. Rich. (ante, vi. 21). 
Hab. Fernando Po, alt. 9000 feet. Cameroons Mountains, alt. 7000- 
9000 feet. (Fl. Nov., Dec.) 
Certainly the same as the Abyssinian plant, of which the tubers 
are eaten, and probably the same also with a Madagasear and 
S.-African one. 
53. JUNCER. 
l. Juncus capitatus, Weig.; Kunth, Enum. Plant. ii. 347. 
Hab. Cameroons Mountains, alt. 7000 feet. (Fl.'Dec.) 
Identical with the European plant, except that the glumes are 
rather longer and more membranous; in form they do not differ, 
any more than the capsules and seeds. The Cameroons specimens 
are triandrous. This minute species is a native of Europe, from 
Norway to Spain, Madeira, and the Canary Islands, and from the 
Azores to Greece and Middle Russia; it has not been found in 
Abyssinia. 
* 2. LUZULA CAMPESTRIS, L. (ante, vi. 22), var. congesta. 
Hab. Fernando Po, alt. 8500—10,500 feet. Cameroons Mountains, alt. 
10,000 feet. (Fl. Dec.) 
Apparently identical with the European plant. The flowers 
are of a very dark colour. This form has not been detected in 
Abyssinia; but the South-African L. Africana, Drége, is referred 
to this variety by E. Meyer (Herb. Hook.). 
54. CYPERACER. 
1. CYPERUS ELEGANTULUS, Steud. Pl. Schimp. sect. ii. no. 574. 
Hab. Fernando Po, alt. 8500 feet. 
This Abyssinian species is united by A. Richard with C. atro- 
nitens, Hochst., and perhaps rightly, but the scales are much larger 
and rather longer in outline. 
2. CYPERUS INGRATUS, Kunth, Enum. ii. 31. . 
Hab. Fernando Po, alt. 6000-7000 feet. Cameroons Mountains, alt. 
6000-7000 feet. (Fl. Dec.-April.) 
lam unable to identify this species with any but the Cape of 
Good Hope C. ingratus; it varies greatly in size, the larger spe- 
cimens resembling the Abyssinian C. derreilema, Steud., and the
