OBS. The first specimen of this beautiful species was sent to me 

 by Captain Aylmer, of the Royal Artillery, a few days before I 

 left Gibraltar for Grenada. During my absence, Miss Mann, 

 daughter of the late General Mann, collected for me several 

 specimens near the Hole-in-the-wall, above the Mediterranean- 

 stair, at an elevation of about 1400 feet. My first impression 

 on seeing the plant was, that it was only a variety of the 

 Iris xiphium, but subsequently I found many characters suffi- 

 cient to constitute it a new species ; and since having compared 

 the specimen with Boissier's description and plate, I doubt not 

 that this is his Iris filifolia : the narrow convolute-canaliculated 

 leaves are almost sufficient to characterise the species. I have 

 seen in Sir William Hooker's Herbarium a more perfect spe- 

 cimen from Gibraltar, presented to him by Dr. Findlay, to 

 which, however, PO name was affixed, until Dr. Hooker decided 

 it to be the Iris filifolia of Boissier. Among my imperfect 

 specimens there are also parts of an Iris resembling those of 

 the I. xiphium, the leaves being narrow and flat ; and it is yet 

 to be ascertianed whether both species grow in Gibraltar. I 

 have been also informed that the Iris filifolia is found on the 

 Queen of Spain's Chair. The true Iris xiphium I gathered on 

 the road to Grenada. There is also, above the governor's cot- 

 tage, another Iris, with flat fan-shaped leaves, though I have 

 not been so fortunate as to see it in flower ; but, from all ac- 

 counts, it seems to be a garden species. The Iris pseudacorus 

 I gathered near Castellar, and second Venta on the road to the 

 Cork -wood.
