4 THE PLANTS OF MILANJI, NYASA-LAND, 
species of Stellaria, Abutilon, Cassia, Ageratum, Bidens, and Celosia. Thirteen per 
cent. of the species are North-African plants, the majority being found in Abyssinia, 
while 19 per cent. are South African. Excluding the widely distributed tropical plants, 
only two species, one of Clausena and the other of Asystasia, occur in both North and 
South Africa. Milanji is obviously in the region where the floras of North and South 
Africa meet, and intermingle in nearly equal proportions with the tropical vegetation 
more proper to the region. 
Among the plants of interest which have a southern facies are two species of Erica, 
carrying this South-African genus into the Tropics, and the fine Widdringtonia, which 
attains a great size, and is fitted to supply in the future a useful timber. Several 
Malagasy plants are in the collection, and among these there are species of Epallage, 
Mascarenhasia, and Brachystephanus, genera that have hitherto been considered endemic 
to Madagascar *. 
It deserves to be noted that a large proportion of the Polypetalous plants belong to 
genera, and often to species, widely distributed over the face of the globe, while a large 
number of the Monopetalz are not known out of Africa. The actual state of the case is 
that 17 per cent. of the genera of the Polypetalz, 35 per cent. of the Monopetalee, 25 per 
cent. of the Apetale, and 28 per cent. of the Monocotyledones are confined to Africa. 
In view of the greater antiquity of the less differentiated plants, it is remarkable that 
the Polypetale, as tested by the genera included in this memoir, have secured the widest 
world-distribution. 
POLYPETALA. (By Epmunp G. Baker, F.L.S.) 
ANEMONE WHYTEANA, Baker fil., n. sp. (Plate I. figs. 1-3.) Radix perennis; caule 
nullo; foliis longe petiolatis, biternatim sectis vel partitis, segmentis subcoriaceis 
ultimis cuneato-obovatis, serratis, apice apiculatis, marginibus plus minusve irre- 
gulariter acute lobatis; petiolis canaliculatis, preecipue ad basin villosis; scapis 
ereetis, ramosis, 3-8-floris; involueri bracteis lanceolatis vel ovatis acutis, villosis, 
interdum trisectis, segmentis anguste ovatis vel lanceolatis; involucelli bracteis 
lanceolatis acutis; pedicellis albo-pubescentibus; sepalis albis, imbricatis, oblongis 
vel ovatis, externe pilosis; stylis brevibus; stigmatibus bifurcatis; receptaculo 
ovoideo piloso; carpellis oblongis, numerosis, glabris vel glabriusculis, sine cauda 
plumosa. 
Hab. Milanji, alt. 6000 ft. No. 100. 
Scape 1-2 ft. high; leaflets 1-13 in. long, 3-1 in. broad; sepals 3-3 in. long; carpels 
7 in. long. : 
This is the second member of the genus which has been found in Tropical Africa, and 
I have called it after the discoverer, Mr. A. Whyte. It has somewhat the habit of a 
Knowltonia, but has not the green sepals which are characteristic of that genus. It 
differs from 4. Thomsoni, Oliver, in Icones Plantarum, t. 1491, in the leaves being 
.. * Since this was written four species of Brachystephanus have been described from Tropical Africa.
