NOTE. Boissier, in founding this species on plants gathered by him 

 in the Sierra de Mijas and Sierra Bermeja, insisted on the extremely 

 filiform leaves, a quarter as broad as those of I. xiphium, on the 

 possession of a perianth tube half an inch or an inch long, and on the 

 colour (a deep blue-purple) of the flower. In his figure not only does 

 the inch-long perianth tube protrude beyond the spathe-valves, but a 

 considerable part of the ovary is also exserted ; and the colour of the 

 flower is a distinctly bluish purple. In the plants gathered at

Gibraltar which I have cultivated, the leaves, though narrower than 

 those of I. xiphium, are much more than a quarter as broad, the 

 ovary is wholly covered by the spathe-valves, the perianth tube is very 

 short (\ inch), and the colour is a rich reddish-purple. These plants, 

 which correspond very closely to that figured in Bot. Mag. t. 5928, 

 approach much nearer to I. xiphium than does Boissier's original 

 plant. The plants gathered at Laraisch, about ten miles S. W. of Tangiers, 

 figured in Bot. Mag. t. 5981, though there named J. tingitana, possess 

 a flower which di fliers markedly from /. tingitana, and is practically 

 identical with that of t. 5928 ; yet the foliage, so far from being 

 filiform, is exceedingly luxuriant, exceeding in breadth even that of
