MAHONIA : TAMARISK 285 



ft Racemes in the axils of bud-scales ; berry 

 globose, blue-black ; leaves pinnate, ever- 

 green, 



Berberis Aquifolium, Ph. Mahonia. Differs but little 

 from the Barberry, except that the leaves are pinnate 

 and evergreen spinescent-toothed and glossy, and the 

 flowers more orange. 



Racemes grouped three to six together, dense-flowered, 

 and up to 10 cm. or so long : bracts about 6 mm. long. 

 Pedicels 5 10 mm., their bracteoles 2 3 mm. long. 

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

 about 34 /JL, 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 

 hypogynous arrangement and apocarpous pistil, the latter 

 of several carpels, and the numbers throughout differ.] 



** Sepals, petals and stamens not in threes, 

 or multiples of three, but in multiples of 

 four or five. Calyx and corolla obviously 

 distinct. Ovary syncarpous. 



t Flowers small, 3 4 mm. in diameter, pink, 

 in dense slender erect spikes. 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. 

 Floral formula K^ (7 4 _ 5 A^ 5 G (3). 



Flowers in lateral, crowded, cylindroid spicate racemes, 

 small, rosy, with 5 stamens and 10-lobed hypogynous
