Boott propr. a Spach communicatum). 
Hab. in Bourbon: Boivin n. ß 994 in herb. Boott propr. 
[Boott t. 301 = Wahlenbergiana type]; Boivin n. 10 ex parte; 
Boivin n. 9 (var. e. pallida, Boott MS.! In Mauritius: Telfair

Glumæ fæmineæ in dorso superiore ob pilos minutos albos 
erectos scabre. Utriculus in parte superiore vel fere usque ad 
basin pilose.

C. ramosa, Boeck. in Linnin, xl. (1876) p. 359 partim. 
Hab. in Bourbon: Richard, in herb. Boott propr. a Spach 
communicata [= Boott t. 302]; Commerson, in herb. Boott propr. 
a Spach communicata [= Boott t. 303]; Bayley Balfour (in herb. 
Kew). In Mauritius: Gardner, in herb, Kew, a manu Boottii 
“ C. Boryana, Schk. ?” inscripta. 
It does not seem possible to draw a line between the C. 
Wahlenbergiana a (with glabrous glumes and utricles) and its 
varr. /3, y, Boott (with seabrous-pilose glumes and utricles). It 
can be seen by the plates that C. cornigera B. minor, t. 309, does 
not differ at all from C. Wahlenbergiana, varr. 3, y, Boott tt. 302, 
303; the plants were all from one locality, and might well be 
one collection. 
Taking the species as widely as this, it becomes the more 
difficult to separate it from many others, especially from the 
Himalayan C. condensata, Nees: in this the spikelets are rather 
smaller, the inflorescence denser, less interrupted, and the leaves 
do not match under the microscope; but I cannot state any 
difference whatever in the female glumes and utricles. As to 
the South-east African C. condensata (C. B. Clarke in Dyer, Fl. 
Cap. vii. p. 305), it is nearer the Himalayan C. condensata than 
it is to C. Wahlenbergiana ; it probably should be esteemed a 
distinct species, unless a large reduction should be made (as is 
quite feasible) in this group of Carez.
