FLORA OF GAZALAND. 15 
with very dark rough bark, and is much sought after for maize stamping 
sticks owing to its toughness. Among the Myrtaces is Syzygium cordi- 
folium, the water-boom of the Dutch, a large tree with shady evergeen 
foliage. Adina microcephala is a tall Rubiaceous tree growing solely on 
the banks of rivers; Chrysophyllum fulvum, reaching a height of at least 
120 feet, is the chief Sapotaceous member of this tree-flora. Maba mualala 
(Ebenacez), Strychnos Burtoni and S. mitis—the latter one of the largest 
trees in the Melsetter distriet,—as well as Acanthocleista zambesiaca 
(Loganiaeez), are worthy of mention here ; also Croton sylvaticus (reaching 
100 feet), Bosqueia Phoberos ( Urticaceæ), and a new Celtis (C. dioica). From 
Mr. Swynnerton’s notes, entered under the species to which they respectively 
refer, it will be seen that a fair proportion of the flora consists of economic 
plants, such as textiles, reputed remedies, rubber, ete. The chief rubber- 
plants of the district are Landolphia florida, L. Катки, and the new 
L. Swynnertonii. Excecaria sylvestris is also mentioned as yielding a milky 
latex apparently containing rubber. Gutta-percha is probably present in 
the latex of Mimusops sylvestris and species of Chrysophyllum. Bosqueia 
Phoberos is another laticiferous tree. The Céara rubber (Manihot G laziovit) 
is cultivated. 
We gratefully acknowledge help rendered by various friends, espe- 
cially members of the Kew staff. Lt.-Col. Prain, Mr. N. E. Brown, and 
Mr. J. Hutchinson have given much assistance with the order Euphorbiacea,. 
Mr. Т. A. Sprague has worked out the Loranthacez, and Mr. A. W. Hill the 
genus Thesium. To Dr. Stapf we are indebted for valuable suggestions as 
to some of the grasses and for permission to publish his MS. name for а 
new species of Pweilostachys, and to Mr. R. A. Holfe for similar suggestions 
on some of the Orchids. Mr. J. В. Drummond has helped with the genera 
Nymphea and Grewia; Mr. S. T. Dunn has described a new species of 
Мена, and Mr. W. P. Hiern a new Diospyros. Газу, Mr. Swynnerton 
himself gave some assistance in certain genera of Polypetalous Dicotyledons, 
and has described several new species, also a new Gardenia. 
The collection has been presented by Mr. Swynnerton to the British 
Museum, in the Herbarium of which the types and other specimens will be 
found. Representative sets have also been distributed to the Herbaria of 
the Royal Gardens, Kew, and the Royal Botanic Garden, Berlin.
