Genera of South African Flowering Plants.

of interest come out when the distribution of the species is compared (which 
is also the case in numerous genera belonging to other orders), but this is 
beyond the scope of the present paper. 
Saxifragaceae. 
Of the three South African genera only the widely spread Motitinia L. f. 
is recorded from the Uit. and P. E. divs. Vahlia Thunb., which has mainly 
a northern and north-western distribution, is absent, and so is Chorisfylis 
Harv. with an eastern distribution stopping short at the Katberg. 
Pittosporaceae. 
Pittosporiwi Banks extends from the eastern and north-eastern parts in 
the southern coast belt to Greorge. 
Cunoniaceae. 
Both Cunonia L. and Plat ylophus Don are recorded from the Uit. or 
P. E. divs. The former is very widely spread in the coast districts of South 
Africa, while the latter does not reach the Cape Peninsula in the West and 
does not extend beyond Van Stadens Mountains in the East. 
Myrothamnaceae. 
Myrothamnus Welw. only occurs in the northern and north-eastern parts 
to Natal. 
Bruniaceae. 
This order is almost restricted to the south-west coast region. Three 
genera only extend to our districts — namely, Berzelia Brongu., Brunia L., 
and PseudohaecMa T. Anders. A little further east, near G-rahamstown, only 
one species of the first is still to be found. Curiously a species of Easpalia 
Brongn. occurs in East Pondoland and Natal. The order appears to be 
largely restricted to the Table Mountain sandstone, and this may account 
for the erratic distribution. 
Hamamelidaceae. 
Trichoclachis Pers., the only South African genus now included in this 
order, is widely spread east of Uitenhage to the Tropics, and extends west- 
wards to George. 
Hosaceae. 
Of the ten South African genera only Alchemilla L., Rnbun L., and 
Cliffortia L., are recorded from the Uit. or P. E. divs. The two former have 
a very wide distribution, while Cliffortia is represented in the south-west 
coast region by a large number of species, thinning out rapidly beyond the 
Van Stadens Eiver, though extending into Central Africa. Of the remain-
