DIAPENSIA FAMILY. Diapensiacece. 

 Low perennial herbs, or tufted shrubs of a mosshke 

 character, very closely related to the EricacecB — the at- 

 tachment of the stamens to the corolla being the prin- 

 cipal difference. — with five-parted tiny flowers whose 

 style is tipped with a three-lobed stigma. Fruit a capsule.

young ; they are crowded toward the ends 



of the branches. The white or pale pink flowers are 

 small, with five blunt lobes between which are curiously 

 fixed the five conspicuous stamens ; they are numerous, 

 and apparently stemless. Branches prostrate and creep- 

 ing. 6-10 inches long. In sandy soil, dry pine barrens. 

 From N. J., south to N. Car. Found at Lakewood, 

 N. J. The name is from two Greek words, box and an- 

 ther, referring to the anthers which open as if by a lid. 



PRIMROSE FAMILY. Primulaceff. 

 Herbs with leaves variously arranged, and with per- 

 fect, regular flowers. The corolla (usually five-cleft) is 

 tubular, funnel-formed, or salver-formed. Stamens as 

 many as there are lobes to the corolla and fixed opposite 

 to them, but the corolla lacking in the genus named 

 Ghmx. Seeds in a one-celled and several-valved capsule. 

 F th rf "1 ^ peculiar aquatic plant of a somewhat 



Hottonia spongy nature, common in shallow stag- 



inflata nant water. Its strange appearance is 



White due to the cluster of inflated primarj" 



June-August flower-stalks which are about ^ inch 

 thick, constricted at the joints, and almost leafless. The 

 leaves are cut into threadlike divisions, and are beneath 

 the water, densely distributed on the floating and root- 

 ing stems. The insignificant whitish flower, \ inch 

 long, has a corolla much shorter than the calyx. The 

 seed-capsule is globular. Stems sometimes 18 inches 

 long. Shallow ponds and ditches, from Mass., to cen- 

 tral N. Y. , and south. Named for Peter Ilotton, botanist.
