Iw the present paper the description of the novelties contained 
in the collections recently received from Madagascar is completed. 
There are no new genera amongst the Incompletæ or Monoco- 
tyledons, except Cephalophyton, of which the material is still 
incomplete. Most of the new species described in the present 
paper belong to the large widely spread tropical genera. Cha- 
racteristically Cape types are represented by Faurea, Peddiea, 
Dais, Kniphofia, and Dipcadi, one species each, by three Aristeas, 
and four Aloes. Of Obetia, of which there are either four species 
or striking varieties in Madagascar in addition to one already 
described by Weddell, there is only a single additional species, 
which is common to Mauritius, Bourbon, and Rodriguez. The 
Bamboo of the forests of Central Madagascar is the same species 
that is found plentifully in the mountain-woods of the centre of 
Bourbon. Of the Alismaceous genus Wisneria one species is 
Indian, one Central-African, and a third found in Central Mada- 
gascar. We have Asiatic types in Lophatherum, of which the two 
species already known belong to the Himalayas, Japan, China, 
and the Malay archipelago; and Eriocaulon fluitans, which 
belongs to a well-marked group of species known previously only 
in Tropical Asia and Australia. 
Mr. C. B. Clarke has kindly undertaken the determination of 
all our Madagascar specimens of Cyperus, and has given me, with 
permission to incorporate it in this paper, a synopsis with 
synonyms of all the species known in Madagascar and the neigh- 
bouring islands. 
In this paper I have not attempted to deal with the Asclepia- 
daceze or Orchidacez, of both of which natural orders there are a 
considerable number in the collections. In both orders a con- 
siderable number of species have been already described from the 
island, with which the new material will require to be carefully 
compared.
