Fam. 161. PRIMULACEAE Sakura-so Ka Primrose Family 



Herbs often with creeping rhizomes; leaves simple, exstipulate, radical or cauline, alternate, opposite, or verticillate, rarely 

 pinnately lobed; flowers in racemes, or panicles, or in simple or superposed verticils, bisexual, usually actinomorphic; calyx 4- to 9-, 

 usually 5-lobed, usually persistent; corolla rotate, hypocrateriform, or infundibuliform, sometimes subcampanulate, rarely absent, 

 imbricate in bud, the limb 4- to 9-lobed; stamens as many as the corolla-lobes and opposite them, inserted on the tube, staminodia 

 alternate with the stamens, rarely present; ovary superior, 1-locular; ovules many, the placentation free-central; seeds small, many, 



the endosperm copious. About 30 genera, with about 500 species, chiefly in the N. Hemisphere, few in the Tropics and the 



S. Hemisphere.
