| + | Whipplea (in honor of Lieut. A. W. Whipple, commander of the surveying expedition to the Pacific Ocean in 1853-1854). Saxifragaceae. Two low shrubs in W. N. Amer. with small opposite nearly sessile lvs., 3-nerved and entire or sparingly dentate, appressed- hairy on both sides, and with small white fls. in terminal cymes: fls. 5- or rarely 6-merous; receptacle turbinate, adnate to the base of the ovary; sepals lanceolate; petals small, oblong-spatulate; stamens 10, rarely 12, with dilated lanceolate filaments and subglobose anthers; ovary half-superior or nearly superior, with 3-6 short styles: fr. a caps. separating into 3-6 1-seeded carpels. They are not hardy N. and rarely cult. in botanical collections only, as they possess no particular ornamental qualities. They are plants of dry regions and demand a well-drained soil; the best place for them is in a rockery. Prop. is by greenwood cuttings under glass and by seeds treated like those of deutzia or hydrangea. |
