The specific type, in the broader sense, is very widely distri- 

 buted — in Spain, Portugal, Morocco, Algeria, the Caucasus, and 

 Turkestan, and in the East from the Levant to West Tibet and 

 Scinde : growing on dry hills, rocky places, and sandy slopes. 

 I can see no reason whatever for separating this plant of the 

 Caucasian Iberia from Brotero's plant of the other (Western) 

 Iberia, as Boissier has done, distinguishing the latter by the 

 name of _D. Broteri. Both plants are extremely variable 

 and typically polymorphous. All the forms are suffruticose 

 below, where the root stock is vertical or oblique, dividing into 

 many branches producing flowering stems and leafy shoots. 



The growth of the leafy shoots is generally vigorous, giving the 

 plant a ca^spitose habit : this is more marked in the Spanish and 

 North-African forms, probably from the habitat. The stems 

 are terete, simple, and frequently unifloral, though they may be 

 forked near the base, strict, slender, and erect or ascending from 

 the crown of the rootstock, and usually fastigiate and equal in 

 height. The leaves are generally glaucous, though in very high 

 stations this glaucescence is absent ; they are linear, adpressed, 

 and 3-nerved (with the nerves very prominent on the under 

 surface), and vary considerably in length; the edges are rough 

 and bordered with the lateral nerves, and the length of the 

 leaf-sheath is equal to or twice its breadth. The bracts vary 

 considerably in form, number, and texture, even in the same 

 localities. In the typical forms there are four pairs (or five, 

 with the lowest pair foliaceous) closely applied along one-third
