EXPLORATION OF ADEN. 
15 
C. von Marchesetti, 1875, 1880, 1881.— Yon Marcbesetti at present 
Director of the Natural History Museum and Botanical Gardens at 
Trieste, visited Aden for the first time in October 1875.. When botaniz- 
ing on the Sbum Sbum Range be found several plants which bad not 
been noticed before in that place, but, at the same time, exposure to the 
tropical sun proved almost fatal to him. 
We do not know in which year Von Marchesetti was a second time 
at Aden. All we could ascertain is that, according to his own statement, 
he collected on this and the former occasion more than three-fourths of 
all the species known from that, locality. 
In October 1880 the Austrian Lloyd opened a new line to Hongkong 
and Von Marchesetti accompanied the first steamer as Medical Officer. 
On his arrival at Aden (18th October) he gathered about 60 specimens. 
From Bombay he sent a description of his excursion to the “ Oesterrei- 
chische Botanische Zeitschrift 33 1 giving a short characterization of .the 
country and some interesting notes on the general aspect of the flora. 
Von Marchesetti proceeded on his tour, but did not reach China. 
He had a second attack of sunstroke in the Island of Pulo Penang and 
was obliged to return to Europe in February 1881. In spite of his 
weakened condition he disembarked at Aden in order to visit a small 
valley which was well known to him for harbouring certain interesting 
plants. Provided with a lantern and helped by a spfendid moon, it did 
not take him long to find what he wanted. But his nightly expedition 
amongst the rocks in the immediate vicinity of the fortifications roused 
the suspicions of a sentry and von Marchesetti was arrested as a Russian 
spy. It was only with great difficulty and after many explanations 
that he at last succeeded in being set at liberty. 1 2 
Annesley, 1875, — A few plants were collected by Captain Annesley 
in 1875. His specimens are at Kew. 
0. Kuntze, 1876.— Kuntze came to Aden on the 9th January 1876, 
towards the end of his scientific tour round the world. He stopped 
there only for three hours and collected 29 specimens of phanerogamic 
plants 3 which, later on, he embodied in his Revisid Generum Planta- 
rum. ;; 
Duplicates of his Aden plants have been acquired by Kew and the 
British Museum. 
J. Collins, 1877.— There is a note in the Proceedings of the Linnean 
Society 4 saying : “ D r. Trimen, F. L. S.. exhibited specimens of the Olibar
