OF THE THIRD TANGANYIKA EXPEDITION. 27 
Recorded in Africa from Suez, Damietta, Kordofan, and Dongola ; also 
specimens in Herb. Kew from Tanganyika Plateau collected by 
А. Carson. 
Known also from India, New Guinea, and North Australia. 
Chara zeylanica, Willd. (C. polyphylla, С. дутпориз, &c., А. Br.. | LAKE 
TaNGANYIKA.—Niamkoli Bay, Aug. 8. No. 19. 
А very small, tufted form of this extremely variable species, in habit 
resembling small compact C. aspera. It does not quite agree with any 
of the varieties described by A. Braun. It is about 3 in. high, with 
short, somewhat connivent branchlets; the spine cells are rather numerous, 
not exceeding in length the diameter of the stem. Branchlets 8-9. 
Segments about 8, the last 1-2 ecorticate. Bract-cells whorled. Fruit 
at the 2nd and 3rd nodes, sometimes at the 4th, rarely at the 1st, 
about :9—95 mm. long x48 through, showing 11-12 stris. Nucleus 
‘62 х'35, almost cylindrical, black, with well-developed calcareous 
covering. 
No. 22 from Mtondwe Вау, Tanganyika, is a larger state of the same form. 
It is young and without fruit. 
C. zeylanica appears to be the commonest Chara throughout the Tropics. 
It also occurs northward to the United States and Bermuda, and south- 
ward to Australia, New Caledonia, &c. 
In Africa it reaches from Egypt southward to Madagascar, and from 
Angola to Somali-land. 
The following Fungi, determined by Mr. V. Н. Blackman, were collected 
on the rotten wood-stays of the canoe on Lake Tanganyika :— Polystictus 
sanguineus, Meyer, a common speciesin warm countries ; a second species of 
Polystictus, the material of which is insufficient for specific determination ; 
and Schizophyllum commune, Fr., a cosmopolitan plant. 
In the following table I have added a few names of species not collected 
by Dr. Cunnington. Of true aquaties I find little to add ; the number of 
marsh-plants might probably be still further increased, but these are of less 
interest.
