HISTORY OF THE BOTANICAL 
German Consul, Mr. Schmuck, was able to send flowers and leaves, 
preserved in spirit, to Vienna. 
In the meantime Dr. and Mrs. Hein had left Aden and reached 
Kishin on the 25th January 1901. Kishin lies east of Aden, beyond 
Makalla, not far to the west of Ras Fartak, on the Hadramaut coast, 
in about lat. 15° 25' N., long. 51° 80' E. Whilst Dr. Hein collected 
much valuable linguistic material, Frau Dr. Hein devoted herself more 
to the natural history of Kishin, and collected, in addition to many 
Zoological specimens, about 100 species of plants, in each case with the 
local names 1 . On their return to Aden, they spent a month at Shaikh 
Oth man. The botanical specimens were presented to the Botanic 
Institute of Vienna, but, as far as we know, no scientific report has 
appeared up to now. 2 
R. Krause, 1905. — Krause published in 1905 his “ Beitrage zur 
Kenntnis der Flora von Aden/'’ 3 He enumerates, without giving the 
description, 178 species as growing in Aden and Little Aden. His 
paper was the most comprehensive publication on the flora of Aden 
after the appearance of Anderson’s Florula. Krause has not visited 
Aden, but, according to his own statement, the specimens of the follow- 
ing collectors were at his disposal : Hildebrandt, Schweinfurth, Ellenbeck, 
Busse, and to a great extent, Defiers, He made, besides, use of the 
publications on Aden in various scientific Journals. 
In the introduction he gives an account of the physical and 
meteorological aspects of the two peninsulas, with some general 
considerations on the flora of Aden and statistical observations on its 
relations to the vegetation of the neighbouring countries. The 
catalogue is followed by a list of 40 species of plants collected in the 
Aden Hinterland by Ellenbeck and Busse. Finally, he gives an 
interesting description with illustrations of the means of propagation 
of the plants indigenous in Aden, which leads to more or less probable 
conclusions as to the origin of the Aden flora. 
In addition to the collectors and botanists mentioned above, the 
following have gathered a few plants at Aden. 
Dr. Boycott (plants at Kew); D, F. A. Ilertey (plants received at 
Kew in March 1892); and three others whose names are known to us 
from printed reports only, Balaiisa, Bom, PeiTOtet.

2 Dr. W. Heim published a paper in the Mitt. d. K. K. Geogr. Ges. Wien, Vol. 46 
(1903), 219-264, entitled Ein Beitrag zur Statistik Sudarabiens,” but this article has 
nothing to do with the natural history of the country explored.
