A NEW SPECIES OF HAEMATOXYLON (LEGUMINOSAE- 
CAESALPINEAE) FEOM GREAT NAMAQUALAND.- 
By Edith L. Stephens, B.A., F.L.S. 
(Plate XVIII.) 
(Eeceived November 5, 1912.) 
(Eead April 16, 1913.) 
The discovery of a South African species of Haematoxylon is of 
particular interest, as the genus has hitherto been represented only by 
one species — H. camyecheanum, L., the log-v^ood tree, a native of Mexico, 
Central America, the northern parts of South America, and the West 
Indies. The species here described was found among rocks at Holoog, 
in Great Namaqualand, by Dr. H. H. W. Pearson, in February 1909, 
during the Percy Sladen Memorial Expedition in South-West Africa, 
1908-9. It is interesting to note that a species of the closely allied and 
likewise typically tropical American genus Hoffmanseggia was found at 
the same place (i?. Burchelli, DC. ; Pearson 4122). This genus ranges 
from Patagonia to Mexico, with two South African species, neither of 
which has hitherto been recorded from the South- West African Region.
