 B. Plant lou- and diffuse. 



1. vesica.rius,Car.(iT.,-lfr(Cfb(HS,Hoi-t.). Flower-of- 

 AN-HOUB. Bladder Ketmia. Trailing Hollyhock. 

 Fig. 1054. A foot or 2 high, bushy-spreailiiig, the mam 

 branches beconiinK prostrate, usually hispid-hairy: Ivs. 

 ■i-5-parted, the upper ones 3-parted, with the middle 

 lobe much the largest, the lobes linear-oblong or some- 

 times widening upwards, coarsely notched, the root-lvs. 

 undivided: tls. solitary in the upper axils, openingwide 

 in the sunshine but closing in shadow, 1-3 in. across, 

 sulfur-yellow or white, usually with a brown eye ; 

 pedicel elongating in fr., and the calyx becoming much 

 inflated. Cent. Afr.-An interesting annual, blooming 

 freely throughout the hotweatherof summer, and thriv- 

 ing in any open, warm place. Seeds are usually sown 

 where the plants are to stand. Excellent (or rockwork. 



2. Tridnum, Linn., to which the above species is usu- 

 ally referred, has much wider and more spatulate and 

 relatively shorter leaf-lohes, which are round-toothed or 

 lyrately lobed: Hs. smaller. I'rom S. En. and Afr. E 

 M. 209. — Sometimes a weed about cult, grounds. 



BB. Pliiiit niosiiy fall, strict and stout. 



3. SabdarifSa, Linn. (II. Bose'Ha, Hort.). Ja- 

 maica Sorrel. liiisELLE. Strong, 5-7 ft. high, 

 nearly glabrous, the stems terete and reddish: 

 root-lvs. ovate and undivided, the upper ones 

 digitately 3-parted, the side lobes sometimes 

 again lobed ; lobes lanceolate-oblong and cre- 

 nate dentate : tls. solitary and almost sessile in the 

 axils, much shorter than the long leaf-stalks; cah\ 

 and bracts red and thick, less than half the length ct 

 the yellow corolla. CUd World tropics.— Widely cult, in 

 the tropics, and now grown somewhat in S. Fla. and S. 

 Calif, for the Heshy calyxes, which, when cooked, make 

 an excellent sauce or .lelly with the flavor of cranberry. 

 The green seed pod is not edible. The.iiiice from the 

 calyxes makes a cooling acid drink. Thrives in hot, dry 

 climates. 



1. e3cul§ntu3, Linn. {Ahrliii'JseJius I'ScuJentus, 

 Moench). Okka. Gumbo. Mostly strict, 2-6 ft., the 

 stems terete and more or less hispid: Ivs. cordate in 

 outline, 3-5-lobed or divided, the lobes ovate-pointed 

 and coarsely toothed or notched: fls. solitary and axil- 

 lary, on inch-long peduncles, yellow, with a red center: 

 fr. a long ribbed pod (5-12 in. long), used in cookery. 

 Trop. Asia. — For culture, etc., see Cilini. A large-fld. 

 form (var. speeiosiis, cf. H. JIanilwt) in Gt. 43, p. 023. 



aa. Perennial Iterhs, mostly grown as harder plants. 



These plants are late summer and fall bloomers, 

 with hollyhock-like fls. They send up new, strong 

 shoots or canes each year. Many of them are perfectly 

 hardy in the N., but even these profit by a mulch 

 covering. Others are tender in the N., and the roots 

 should be taken up after frost and stored in a dry, 

 warm cellar. Keep them just moist enough to main- 

 tain life in them. l\lany times the roots of these her- 

 baceous species are set in large pots in the sjiring, 

 and they then make most excellent specimens. All the 

 species require a deep, rich soil and i)leuty of water. 



B. Foliage green and itsatrlli/ glahrous. 

 .". MAnihot, Linn. Tall and stout (3-9 ft.), glabrous 

 or hairy: ivs. large, palraately or pedately 5-9 parted 

 into long and narrow oblong-lanceolate dentate lobes: 

 involucre bracts oblong-lanceolate, falling after a time 

 (as does the calyx) : fls. large (4-9 in. across), pale yellow 

 ( sometimes wh i te ) ,with a purpjie eye : capsule oblong and 

 hispid. Old World tropics, and spontaneous in S. states. 

 B.M. 1702; 3152 (Ivs. more cut). S.H. 2:203. -This is 

 apparently the Sunset Hibiscus of the tratle; also the 

 t^ueen of the Summer Hiljiscus. lu botanical works, FT. 

 Man/hot is said to be an annual, l)ut as known to horti- 

 culturists it is a jierennial. For a discussion of this 

 point as related to the limitations of the species, see G. 

 C. UL 22:249; (in. 53, p. 127 (and plate 1157). Botani- 

 cally, the species is allied to//, esciilenliis. Not hardy in 

 the open in the North, but the roots may bo taken up 

 in the fall and carried overwinter in a warm, drycellar. 

 In the middle states and South, it niiiy be expected to 

 survive if well mulched. Grows readily from seeds.

 sinuses often rounded and enlarging, the lobes angled 

 or toothed and blunt : fls. 3-4 in. across, yellow, with 

 purple in the base. S. Car. south.— Not hardy North. 



7. coccineus, Walt. (//. speeidsns, Ait.). Green and 

 glabrous throughout, 3-4 ft.: Ivs. palmately lobed, or 

 the lowest and sometimes all of them palmately com-

 toothed : fls. very large (5-0 in. across), rose-red, the

 lobes at base), the middle lobe ovate lanceolate or tri-
