Soeotra. Not uncommon. B.C.S. n. 102. Nimmo. 



Distrib. Arabia, Somali Land, Egypt. 



A widely-spread plant of the region of the Red Sea, varying somewhat in 

 the relative length and breadth of leaf, in the elongation or contraction of the 

 inflorescence, and in the clothing of the calyx-tube. I do not find any 

 sufficient characters justifying the maintenance of either the Arabian or 

 Scindian form as distinct species. 



One of Nimmo's Socotran collection.

Distrib. South Arabia, Mokha. 



This species, first described by Forskal and figured by Vahl, appears to have 

 escaped the notice of collectors in recent times. In Kew Herbarium I find, 

 under the name Statice axillaris, a coloured sketch by Col. Playfair of an Aden 

 plant which has much resemblance with this species. But there are no 

 specimens of such a plant from Aden, nor do I find any other record of its 

 occurrence there. T. Anderson does not notice it. Graham in the addenda 

 to his Catalogue of Bombay plants describes Eurychiton adensis as an Aden 

 plant. This is referred by Bentham and Hooker (Gen. PI. ii. 626) to Statice, 

 and they remark " si corolla recte gamopetala descripta ad sectionem Siphou- 

 antham pertinet. Collectores recentiores in vicinibus Aden S. axillarem, Forsk., 

 solam invenerunt quae ad Limonii species suffruticosas habitu Armeriastro 

 accedentes pertinet." Graham's description of the flower of his plant suits 

 S. cylindrifolia, that of the foliage suits S. axillaris. Whether or no the plant 

 occurs at Aden, its existence in south Arabia has been demonstrated recently 

 by Schweinfurth, who sends excellent specimens from near Bolhaf, where the 

 Arabic name for it is " Tissumm." Boissier (loc. cit.) suggests its occurrence in 

 Upper Egypt. 



2. VOGELIA. 

 Vogdia, Lamk. Illustr. ii. 147, t. 149 ; Benth. et Hook. Gen. PI. ii. 628. 



A small genus, including three species of shrubby plants, one of which is 

 peculiar to south Africa, another is endemic in Soeotra, and the third, which is 

 found in north-west India and Arabia, extends also to Soeotra.
