Distribution : — Arabia, Nubia, Egypt; 
Note Krause considers it probable that the specimen found and 
named as Pancratium tortaosnm Herb, by Anderson and Defiers is 
identical with the following species, P. maximum Forsk. In favour of 
his opinion he mentions the fact, that the true P. tortuosum is almost 
exclusively found in sandy plains and mostly in the immediate 
neighbourhood of the sea, whilst rocky ravines are the favourite locality 
of P. maximum. 
The author of the c Florula ' says on page 38 : “ My plant, though 
not in flower, is doubtless the same as Herbert's species. It grows in 
clumps in one or two of the narrow valleys in Aden. Boissier quotes 
Schimper's number as 676 ; but the plant in the Hookerian herbarium 
is marked 876. My description is drawn partly from my own specimens 
and partly from the manuscript diagnosis of Herbert in the Hookerian 
herbarium." 
'We have examined Anderson's specimen and we do not doubt that his 
statement is correct. Thomson found the same species at Aden after the 
publication of the Florula, in April 1861. As to Defier's specimen we 
have no reason to doubt a priori its correct identification.
