FLORA OF ADEN. 
double ; setse of outer row very short (three times shorter than the 
achenes), rigid, of inner row 15-barbate. 
Achene ^ line long, subhirsute. 
Flowers and fruits : — -Jan. 1872 (Thomson), Jan. 1876 (Kuntze), 
Jan. 1880 (Balf.), March 1878 (Perry), April 1861 (Thomson), Novem- 
ber 1888 (Schweinf,), December 1847 (Hook.). 
Locality : — Near the sea (Hooker) ; Wadi Maala (Schweinf.) ; great 
valley between Steamer Point and town (Marchesetti) ; without 
locality (Perry, Balfour, Kuntze, Thomson, Birdw.). 
Apparently endemic in Aden. 
Note : — This plant has caused a great deal of confusion. We 
trust that the following details may help to clear up the doubts 
existing at present : 
J. D. Hooker was the first to collect a specimen at Aden ( f near 
the sea/ Herb. Kew) on the 20th December 1847. When, a few 
years later, Hooker visited Aden in company with Thomson, they did 
not gather this plant. Hooker's specimen of 1847 was, therefore, the 
only material which was at Anderson's disposal when he published 
his ‘Florula' in 1860. The specimen, consisting of a tiny branch with 
a few flowers, is still preserved at Kew. Anderson called it Varthemia 
Arabica Boiss. Diag. YI, p. 74 (cf. Florula Adenensis, p. 22). 
Anderson gives this reason for putting the plant under the genus 
Varthemia in spite of its having a double pappus : 
u De Candolle describes Varthemia as having the pappus uniserial ; 
in five species that I have examined, in addition to the original species 
V • Fersica , the pappus is in two rows, the outer consisting of short rigid 
setae/' (Florula 1. c.) 
The second specimen was collected by Thomson on the 11th April 
1861 and is named Varthemia arabica Boiss. in Herb. Kew. A third 
specimen, gathered by the same botanist in January 1872, shows 
on its label : Fulicaria ( Varthemia arabica T. Anderson, non Boiss.). 
On the 9th January 1876, Kuntze made a small collection of Aden 
plants. Amongst the specimens we find Anderson's Varthemia 
arabica under the new name Fulicaria iphionoides O. Kze. to which is 
added the synonym Jphiona arabica B. Hgp. (No. 7648 Herb. Otto 
Kuntze in Herb. Kew.) No description, however, has ever been published 
by Kuntze. 
Perry's and Balfour's specimens of the years 1878 and 1880 res- 
pectively bear the label : Fulicaria ( Varthemia arabica T. Anders.). 
Shweinfurth collected the same plant on the 25th November 1888 
and named it in his herbarium Fulicaria adenensis Schweinf. (= Varthe 
mia arabica T. Anders., non Boiss.).
