quote the last Official Report on the Bechuanaland Protectorate 
(Colonial Reports—Annual, No. 593 for 1907-8) :— 
“ Trrigation at present is unknown and, so far as can be seen, 
will never be possible on a large scale except in that remote portion 
of the territory known as Ngamiland. There, a great river, the 
Okavango, flowing from the north, enters the Protectorate and 
gradually loses itself in marshes of vast extent. . The annual 
volume of water which the Okavango carries is enormous, and 
to-day this element, so precious in South Africa, disappears in the 
middle of the sub-continent as completely as though it were 
discharged into the ocean. It is not too much to suppose that in 
the days to come the flow of the Okavango will be controlled, and 
that by a system of canals that region, to-day a desolate swamp, 
and many. hundreds of square miles bordering upon it, may become 
land capable of the highest cultivation, Some day Ngamiland 
may be known as the Egypt of the South,” 
List OF PLANTS COLLECTED IN NGAMILAND AND THE 
NORTHERN PART OF THE KALAHARI DeEsER?, chiefly in 
the neighbourhood of Kwebe and along the Botletle and Lake 
Rivers. 
N. E. Brown. 
This collection contains 320 Dicotyledons, 52 Monocotyledons 
and 2 Ferns, a total of 374 species, of which 92 are new. The 
aie level of the region in which they were collected is 3,000 
eet above sea-level, with hills rising a few hundred feet higher, 
since the highest elevation recorded on any of the labels is 
3,600 feet. The specimens are all well selected, carefully preserved 
and mostly very complete, and are accompanied by valuable notes 
on the habit, colour of the flowers, &c. Mrs. Lugard also made 
a large series of very accurate coloured drawings with dissections, 
from which much aid has been obtained in preparing the following 
descriptions, From the notes on the labels the general composi- 
tion of the Flora of the region appears to be somewhat as follows:— 
Trees about 29, varying from 15 to 40 feet in height ; shrubs or 
bushes 44 or over; succulent plants about 10; annuals yaa 
probably others that are not so indicated may belong to this group; 
thorny or prickly plants 17; climbing or twining plants about 30, 
esides many that scramble over bushes or rocks or creep rhe 
eenish or 
green, mauve, purple, cream, orange, pink, red, blue, gr Lee 
greenish-white, magenta, claret and scarlet.
