typo (2) majora latiuscula, juniora angustissima fere setacea. 
Hab. Montpellier, Mt. Ventoux, and Val d'Eynes in the 
Pyrenees. 
Forma elongata.—Caulieuli valde elongati 3-7-flori. Folia

Caules 3-4-flori. Folia lineari-subulata rigida ciliolata. 
Possibly the same as lusus 2 forma stricta of preceding var., but 
the leaves uniformly ciliolate instead of only towards the base.

, This polymorphous species varies considerably within narrow 
limits. The forms have been grouped into seven varieties on 
the characters of the length, breadth, and direction of the leaves» 
the size of the flowers, and the number of pedicels springing 
from one axis. The leaves are frequently imbricated on the stem, 
but never tetrastichous. Cosson proposed to sink A. incrassata 
also in this species; but in typical specimens of A. grandiflora 
the stem is distinctly 4-angled, especially in vigorous specimens 
with furrowed surfaces between the angles; the seeds also are 
more distinctly tubereulate. In one of the specimens growing 
this year in the Alpine house at Kew Gardens, most of the 
lowers had 4 styles.
