EXPLORATION OF ADEN. 
17 
manuscript volume of the Kevv Herbarium there is a note by Hunter 
saying : — 
“ The districts visited will be described in the Monograph hereafter 
to be forwarded. They are mostly in the hills and they may be said to 
be between the 13° and 14° of N. Lat., and the 44° and 45° of E. Long/* 
We have not been able to ascertain what “Monograph** he was 
alluding to or whether that Monograph has ever been published. 
As most of Hunter's specimens give as locality the “ neighbourhood 
of Aden ," it is difficult to say which of his numerous plants were 
collected on the peninsula of Aden and which in Aden Hinterland. We 
shall, therefore, mention Hunter's plants only in those cases where the 
same species has been reported from Aden by some other collector. 
J. W. Yerbury, 1884. — Major Yerburv, well known for his valuable 
contributions to Aden Zoology, made a collection of 57 plants at Aden 
in spring 1 884. Amongst them there was a new species which Bidley 
described under the name of Albuca Yerburyi} The specimens are in 
the British Museum. 
H. R. Beevor, 1884, — Dr. Beevor collected at Aden in November 
1884. His specimens, which are not very numerous, were presented to 
Kew. 
G, Sell weinfur til, 1881, 1888, 1889 .-‘-Since the publication of 
Anderson's Florula our knowledge of the flora of Aden had become raoire 
or less stationary. A few new species had been added to the list of 
Aden-plants, and some others had been observed at Aden which had 
escaped the collectors of earlier years, but the fact of their occurrence 
on that barren peninsula was not generally known. With Schweinfurth, 
however, who has done so valuable a work for the botanical exploration 
of the countries of the Bed Sea, our knowledge of the vegetation of 
Aden has been greatly advanced. Keen eyes and an enormous store of 
information regarding genera and species enabled him to make many an 
interesting find in places where other collectors had looked for them in 
vain. Schweinfurth visited Aden during the following months : March 
1381, November and December 1888 , January and February 1889 , and 
November 1889 . Each time he had a rich harvest. The results of his 
travels, including his visit to Aden, were published in the <( Bulletin de 
1' Herbier Boissier " under the title : “ Sammlung arabiscb-aethiopischer 
Pflanzen. Ergebnisse von Beisen in den Jahren 1881 , 1888 , 1889 , 1891 , 
1892 ." 1 2
