FLORA OF ADEN. 
Pod l£ inches long, 1 line broad, linear, strigose, undulate, rostrate 
acuminate with the persistent style, surrounded at the base by the 
persistent calyx. Seeds 6 — 10, lenticular. 
Flowers: — March (Schweinf.) ; October (Marchesetti) . 
Locality: — Plain of Maala, on gravelly ’ground and volcanic debris 
(Schweinf.); Goldmore Valley (Defl.) ; great valley between Steamer Point 
and town (Marchesetti) ; slope of S hum Shurn Range (Ellenbeck, ex 
Krause) . 
Distribution : — Yemen, Island of Neymen in the Red Sea. 
Note : — There are some specimens from Aden in Herb. Kew, named 
Argyrolobium arabicum Jaub. et Spach, which cannot belong to this species, 
the pod being quite different from that of the typical plant of Jaub. et 
Spach. One was collected by Perry in March 1878 and the other by 
Eeevor in November 1884. In the same way we do not think that 
Hooker's and Thomson's specimens (December 1847 and February 1851) 
are identical with the type of Jaub. et Spach.
