WAITZIA (P. A. C. Waitz, born 1708, state physician 

 to the Dutch at Samarang, Java; wrote on Javanese 

 plants). Compdsitw. Includes one of the rarer "ever- 

 lasting flowers," a half-hardy annual which grows about 

 \y<i ft. high and bears flat-topped clusters of yellow 

 flower-heads, with a golden disk. The clusters are 

 about 5 in. across, and the heads 2 in. across, the showy 

 part being the involucral bracts, which are arranged in 

 4 or 5 series, and are petal-like in character but of 

 stiffer texture than ordinary petals. Waitzia is a genus 

 of 7 species of Australian herbs, mostly annuals: lvs. 

 alternate, linear or nearly so: fl. -heads in terminal 

 corymbs or rarely in oblong, leafy racemes: involucre 

 various in outline, the bracts overlapping in many rows, 

 all colored and petal-like: receptacle flat, without scales: 

 anthers provided with tails of microscopic size: akenes 

 somewhat compressed, glabrous or papillose, termi- 

 nating in a slender beak; pappus of capillary bristles 

 usually cohering at the base, simple, barbellate or plu- 

 mose. The genus is distinguished from Helipterum and 

 Helichrysum by the beaked akenes. Flora Australien- 

 sis, vol. 3. 



grandifldra, W. Thompson. (The authorship of this 

 species is credited to Naudiu by Index Kewensis.) 

 Half-hardy everlasting or "immortelle," annual, ex- 

 ceeding 18 in. in height: lvs. lanceolate, long-acumi- 

 nate, sessile, green above, slightly villous beneath, 

 prominent midrib beneath: fls. yellow, in terminal 

 corymbs. F. 1865:41, where itwas originally described. 

 Probably the most desirable of the genus. It seems to 

 have replaced W. aurea, the favorite of the previous 

 generation, being larger-fld., more robust, and rather 

 easier of cultivation. ^y jyj 



WALDSTEtNIA (Franz Adam, Count of Waldstein- 

 Wartenburg, born 1759 at Vienna; wrote with Kitaibel 

 an illustrated work on rare plants of Hungary; died 

 1823). Bos&ceir. The Yellow or Barren Straw- 

 berry, Walsteinia 1ragarioid.es, is a little plant that 

 looks much like a strawberry plant, but it has yellow 

 flowers and bears no edible fruit. It is a hardy North 

 American tufted perennial herb, about 4 in. high, with 

 glossy lvs. composed of 3 wedge-shaped lfts. and 5- 

 petaled fls. less than X A in. across. It comes with the 

 first rush of spring, and continues to bloom until sum- 

 mer. There is no satisfaction in growing only a few 

 plants of this wild flower. The plant is appropriate to 

 the rockery, where every effort should be made to in- 

 duce it to form a dense mat. Masses of the Yellow 

 Strawberry have been used with good effect for edging 

 shrubbery borders, and the plant is listed by several 

 nurserymen. 



Only 4 species of Waldsteinia are well known. They 

 are hardy, creeping, perennial, strawberry-like plants: 

 lvs. alternate, mostly basal, long-stalked, entire, lobed. 

 3-5-cut or with 3-5 lfts., the lfts. crenate or incised: 

 scapes bracted, bearing 2-5 yellow fls.: petals 5, obo- 

 vate, about as long as the calyx-lobes; stamens indefi- 

 nite : carpels 2-b": akenes obliquely obovoid, dry or 

 slightly fleshy. Natives of north temperate zone. 



fragarioides, Tratt. Fig. 2708. Popular description 

 above. Pubescent or nearly glabrous: lfts. dentate or 

 crenate except at the base, 1-2 in. long: scapes corym- 

 bosely 3-8-fld. : akenes 4-6. May, June. Woods and 

 shaded hill-sides, New England to Minn, and Ind., 

 along the Alleghanies to Ga. B.B 2:218. R.H. 1890, p. 

 510. B.M. 1567 and L.B.C. 5:408 (both as Dalibarda 

 fragarioides). ^r jj

WALLlCHIA (Nathaniel Wallich, 1786-1854, Danish 

 botanist; wrote on plants of India). Palmacew. Three 

 species of Himalayan palms, one of which, the first de- 

 scribed below, is cult, outdoors in S. Fla. and S. Calif, 

 and in Eu. under glass, and the second, while not ad- 

 vertised in America, is believed to be in a few northern 

 greenhouses. 



Low palms, cespitose, with short branching caudices, 

 or in 1 species tall: lvs. densely fasciculate, terminal, 

 distichous, scaly, unequally pinnatisect: segments soli- 

 tary or the lowest in groups, cuneate at the base, ob- 

 long-obovate or oblauceolate, erose-dentate, the terminal 

 one cuneate; niidnerve distinct; nerves flabellate; 

 margins recurved at the base; petiole slender, laterally 

 compressed; sheath short, split, with the margins deeply 

 crenate: spadices short-peduncled, the staminate droop- 

 ing or recurved, ovoid, much branched, densely fld., the 

 pistillate looser, erect; spathes very numerous, slender- 

 coriaceous, the lower ones the narrower, tubular, the 

 upper ones cymbiform, entire, imbricated: fls. medium, 

 yellow: fr. ovoid-oblong, red or purple. Stove palms. 

 For culture, see Didymosperma. 



Wallichia is allied to Didymosperma, Arenga and 

 Caryota, differing in having 6 stamens instead of an 

 indefinite number. Caryota is the only one of this 

 group with ruminate albumen. Didymosperma has a 

 cup-shaped, 3-lobed calyx, and in Arenga the calyx 

 has 3 distinct sepals.
