 tum. Leaves linear, greyish-green on both sides. Flowers small, dark purple, 

 forming with small bracts a dense spike, quadrangular in section, surmounted by 

 a bunch of large, sterile purple bracts. Occasionally the large bracts are quite 

 white (var. albicans Conill.). 



Very common in dry places on the littoral, especially in pine-woods, heaths, 

 and maquis. February-June. Much used on the Riviera for placing among 

 clothes, as is the common cultivated Lavender in England.

 in height. Leaves green finally, linear or linear-oblong, shortly downy. Flowers 

 bluish, scented aromatically. Bracts broad, oval membranous, brown. 



On hills, except on the littoral. June-July. 



L. latifolia Vill. Broad-leaved Lavender.' A similar under-shrub, but 

 greyer, with very short woody stem. Leaves oblong-spathulate. Flowers
