 oblong-lanceolate to linear, }4r\ in. long: fls. white,

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 smaU opposite nearly sessile Ivs., 

 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; 



?Vir 3999. Wigandia caracasana. 

 (XX) 



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 hi a rockery. Prop, is by greenwood cuttings under 

 glass and by seeds treated like those of deutzia or 

 hydrangea. 



modesta, Torr. Sarmentose; the long shoots with 

 numerous short upright flowering branchlets, pubes- 

 cent: Ivs. broadly ovate to elliptic, acutish, with a few 

 shallow teeth or nearly entire, appressed-hairy on both 



sides, H-l in. long: fls. white, about K m - across, in 

 slender-stalked dense cymes Yy-Yiva.. long. May. Ore.,

 lerella utahensis, Heller). Much -branched, upright 

 shrub, to 2 ft., pubescent: Ivs. elliptic-ovate to linear- 

 oblong, acute, entire, ^-J^in. long, appressed-hairy 

 on both sides: fls. white, hi terminal small cymes

WHITFIELDIA (named after Thomas Whitfield, 

 intrepid naturalist who made several explorations into 

 Trop. W. Afr. and brought back many choice plants). 

 Acanthacese. Glabrous shrubs, rarely used as warm- 

 house ornamentals: Ivs. opposite, entire: fls. white or 

 brick-colored, solitary hi the axils of opposing bracts, 

 arranged in a terminal raceme; calyx 5-parted, segms. 

 membranaceous, colored, oblong or lanceolate; corolla- 

 tube swollen almost from the base or slender-cylindrical 

 and abruptly inflexed above widening to a campanu- 

 late throat, 5-lobed, lobes ovate or oblong-lanceolate; 

 stamens 4, in pairs. About 17 species, Trop. Afr. The 

 material which has been offered hi Amer. as W. lateritia 

 is really Jacobinia carnea (see Vol. Ill, p. 1714): the 

 true W . lateritia, Hook., is rarely cult, and is a tender 

 evergreen shrub about 3 ft. high: Ivs. ovate or oblong- 

 ovate, wavy: fls. red; corolla bell- or funnel-shaped. W. 

 Trop. Afr. B.M. 4155. F.S. 1:36. 



WHITLAVIA: Phacelia. 

 WHORTLEBERRY: Vaccinium. 

 WTODRINGT6NIA: CaUUris. 



WIGANDIA (named after Johannes Wigand, Pomer- 

 anian bishop; wrote on plants; 1523-1587). Hydrophyl- 

 lacese. Tall hispid perennial herbs or subshrubs, used 

 for subtropical bedding, or may be grown in the green- 

 house. 



Leaves alternate, large, rugose, doubly dentate, 

 cymes terminal, large, dichotomous: fls. sessile, 1- 

 sided along the branch; calyx-segms. linear; corolla- 

 tube shortly and broadly campanulate, scaled inside; 

 limb broad, spreading, 5-lobed, lobes imbricate; sta- 

 mens 5; ovary rather perfectly 2-celled: caps. 2-valved. 

 About 3 or 4 species, widely dispersed in the moun- 

 tains of Trop. Amer. Monographed by A. Brand hi 

 Engler's Pflanzenreich hft. 59 (IV. 251). The species of 

 Wigandia are very much confused in current reference 

 books, as well as hi the trade. The following account is 

 based on Andrews revision of the genus hi R.H. 1861 : 

 371, with an important change in the name of one spe- 

 cies. In respect to W. urens, Andr6 follows the previ- 

 ous revision by Choisy hi DC. Prod. 10:184. The com- 

 bination Wigandia urens was first used by Kunth, who 

 applied it to a Mexican plant. Before this, however, 

 another plant of the same family but a native of Peru 

 had been called Hydrolea urens. When Choisy came to 

 monograph the whole family he transferred Hydrolea 

 urens to the genus Wigandia and called it Wigandia 

 urens, Choisy. He therefore had to rename the Mexi- 

 can plant, and this he called Wigandia Kunthii. 



Wigandias are chiefly valued as foliage plants for 

 subtropical bedding, because of their very showy char- 

 acter. Their leaves are covered with stinging hairs, 

 similar to nettles. Many large specimens may be seen 

 in California, but the plants are considered to be rather 

 coarse and straggling. They are generally raised from 

 seed every year, the seed being started indoors as early 

 as January. The plants attain a height of 6 to 10 feet 

 in a single season. They are unsatisfactory greenhouse 

 plants, as they do not grow vigorously indoors. The 

 roots may be kept over winter in a frostless place and 

 stock may be secured in spring by cuttings. In gen- 

 eral, the plants are not much used in North America.
