 and evergreen spinescent-toothed and glossy, and the 

 flowers more orange.

 Pollen pale yellow, punctate, irregular, rounded and large, 

 about 34 fi, with crossing rills as if tetrads. 



[Clematis also comes here, except that its perianth is 

 single, whence it is dealt with on p. 277. It has the 

 hypog}Tious arrangement and apocarpous pistil, the latter 

 of several carpels, and the numbers throughout differ.]

 or multiples of three, but in multiples of 

 four or five. Calyx and corolla obviously 

 distinct. Ovary syncarpous.

 in dense slender erect sjiikes. Stamens 4 5 ; 

 fruit a capsule; seeds comose. Branches 

 slender and crowded with minute scale-like 

 imbricated leaves. 



Tamarix Gallica, L. Tamarisk. Leaves minute and 

 scale-like, crowded and imbricate on the slender branches, 

 reminding one of the Cypresses; but this resemblance, 

 as also the still stronger resemblance of the catkins, 

 capsules and comose seeds to Willows, is purely superficial.
