CONCLUSIONS. 
Nore (A). On the Distribution of the Sub-Order Mapanie® 
in India. 
The whole material that has come through my hands from the 
herbaria is only 114 collections, representing 22 closely-allied 
species. Nevertheless, much may be proved by this scanty 
material; for the plants are large or striking, and if they are 
not collected while obscure Scirpus, Fimbristylis, are collected in 
abundance, we may assume that the individuals of Mapaniz are 
not numerous and that they are in very narrow localities. 
(The whole sub-order lies between 27? N. L. and 27° S. L. in 
both hemispheres except the distinct genera Chrysothrix at the 
Cape and Chorisandra in Cape Town.) | 
The two large genera Mapania and Hypolytrum occur in 
America, Africa, Asia, and Oceania, and are concomitant every- 
where (remarkable if the view of Pax of their wide separation is 
correct): thus, in India there is a cluster of Hypolytrum 
in Ceylon, also of Mapania; there is a cluster of Hypolytrum 
down the Malay Peninsula to Singapore, also of Mapania. The 
two genera are similarly linked in the American distribution, the 
centre of gravity for both being in Guiana and Lower Amazon. 
The aetual Indian distribution is (1) Ceylon (South and West), 
continued up the Malabar Ghats to Bombay. (2) Singapore 
and Malay Peninsula, continued up through Pegu and Chittagong 
to the Brubmapootra—with one species in Sikkim. 
Nore (B). The Geographie Distribution of the Caricinex 
of India. 
The Caricinez are especially worth attention in their geographic 
distribution, because they are strictly indigenous ; of the 1117 
examples above tabulated, there is perhaps not one that was not 
truly wild. Of Cyperus, Fimbristylis, &e., huge quantities of 
many species are cultivated by man with his corn; of Aobresia 
and Carex I know no cornfield weed or species that accompanies 
man in any way. 
In order to shorten the present article, the Indian Caricinese 
are arranged in three groups, viz. :—(1) Proprie, i. e. the sect. 
Proprie of Eu-Carex, the few closely-allied sect. Atrate being 
thrown in; (2) the sect. Indice of Eu- Carex; (3) the remainder 
of Cariciuez, being mainly Vignea (with Kobresia and the few
