2 NEW SOMALILAND POLYPETAL^E. 



Among European species E. canadensis has somewhat the habit 

 of E. stricta Host = E. crlcetorum Jord., from which it differs by 

 the branches being confined to the lower portion of the stem, by its 

 opposite and gLandnlar bracts with fewer teeth, the upper teeth 

 being less acute and not aristate, by the capsule being broader at 

 the apex and truncate and exceeding the calyx-teeth, &c. 



E. Canadensis differs from £". horealis Towns., in which the 

 branches are not confined to the lower portion of the stem, and 

 they are erect-patent and not so prolonged, the teeth of its leaves 

 and bracts are less acute, and its capsule is decidedly emarginate. 



As to the history of E. canadensis, it is difHcult to form an 

 opinion without further knowledge of its present geographical 

 distribution ; whether it be an importation from Europe at a 

 remote though historic period, modified by climatic or other in- 

 fluences, or whether it be the descendant of an ancient but indi- 

 genous form. As regards E. americana Wetts., Prof. Wettstein 

 inclines to the idea of importation, as stated in his Monograph, 

 p. 128.

Closely allied to M. elliptica R. Br., and, like that plant, a 

 diffuse or bushy herb, woody below, with branches, leaves, &c., 

 covered with a close cinereous or hoary tomentum. Leaves ellip- 

 tical or oblanceolate, apex acute, margin entire or obscurely 

 sinuate-dentate, lamina at the base narrowing gradually to bottom 

 of petioles, lamina measured from point of insertion of petioles 

 2-2 f in. long, breadth at broadest point f-f in. Pedicels short, 

 erecfc, covered with hoary tomentum, axillary and solitary, but
