MAMMEA

from the axis at maturity. Some 70-80 or more species, 

 in Amer. and S. Afr. The garden species are perennials 

 of easy cult., blooming in the hot weather. 



A. Fls. white, with eye. 



. hypomadarum, Sprague. Shrubby, sometimes reach- 

 ing 10 ft., slender-branched, free-flowering : Ivs. variable, 

 usually 3-lobed and more or less toothed, sparsely 

 soft-hairy on both sides: fls. white with rose-purple 

 eye, about 1J^ in. across, axillary, solitary or 2 or 3 

 together; petals obliquely obovate, retuse; calyx-lobes 

 ovate, acuminate and ciliate; bractlets 3, spatulate- 

 linear, ciliate. S. Afr. G.C. III. 43:394; 44:92. B.R. 

 295 (as Malva capensis). This species was founded as 

 late as 1908, although in cult, in Great Britain for a 

 century under other names, as M . capense, M. virgatum, 

 M. grossulari&folium. Prop, by cuttings under glass in 

 late spring, giving bloom in a cool greenhouse the fol- 

 lowing season. 



AA. Fls. colored. 



capense, Garcke (Mdlva capensis, Linn.). Shrubby 

 and branchy, slightly viscid: Ivs. ovate-oblong, some- 

 what 3-lobed and angled, unequally toothed: fls. 1-2 

 on axillary peduncles, purple; involucel variable in size, 

 the bracts lanceolate to ovate-lanceolate and shorter 

 than the ciliate calyx-lobes: carpels glabrous. S. Afr. 

 Offered abroad and also in S. Calif. Var. Lindemuthii, 

 Hort., said to be a graft-variety procured by working 

 M. capense on Abutilon Thompsonii: Ivs. 3-lobed, yel- 

 low-variegated: fls. small, rose-red shaded violet. See 

 also Kitaibelia Lindemuthii, p. 1738. It is doubtful 

 whether M. capense is in cult.; the plants passing under 

 this name may be M. hypomadarum. 



lateritium, Nichols. (Mdlva lateritia, Hook.). Pros- 

 trate, hirsute, 6 in.: Ivs. 3-5-lobed, truncate at base, 

 the lobes cuneate to broad-oblong: fls. long-peduncjed, 

 solitary, brick-red; calyx-lobes ovate and spreading; 

 involucel of 3 ovate bracts; petals round-cuneate, yellow 

 at the base. S. Amer. B.M. 3846. Malva lateritia is 

 offered in England where the root is said to be hardy 

 in ordinary winters, producing "very pretty peach- 

 colored" fls. Useful for covering dry banks in the sun. 



coccineum, Gray (Mdlva cocdnea, Nutt. Cristaria 

 cocdnea, Pursh). A tufted canescent plant, 4-18 in. 

 high, with running rootstocks: Ivs. 1-2 in. across, 

 pedately 3-5-parted or -divided, the narrow divisions 

 again cut or cleft: fls. brick-red or coppery, in a short 

 terminal raceme: carpels round-kidney-shaped, inclosed 

 in the incurving calyx-lobes, 10-15, reticulated, inde- 

 hiscent, 1- or 2-seeded. Neb. to Manitoba and west. 

 B.M. 1673. Var. grandifldrum, Hort., has large deep 

 scarlet fls. 



campanulatum, Nichols. (Mdlva campanuldta, Paxt. 

 Mdlva purpurdta, Lindl.). Two ft. or less high, hairy: 

 Ivs. pedately 3-7-lobed, the lobes deeply cut and 

 toothed: fls. rose-purple, an inch across, hi a loose 

 terminal raceme, blooming until killed by frost; 

 bractlets very narrow. Chile. B.M. 3814. B.R. 1362. 

 G.C. III. 48:179; 52:193. P.M. 9: 173, and R.H. 

 1843:325. 



M. Gilliesii, Baker. More or less procumbent: Ivs. hairy, 

 palmately divided: fls. 1 in. or more across, bright red. S. Amer. 

 M. splendidum, once listed, is probably M. Thurberi var. laxi- 

 florum, Gray (M. splendidum, KelL), in S. Utah to S. Calif. Shrub, 

 becoming 12 ft. or more, gray-tomentose: Ivs. roundish and mostly 

 subcordate, 3-cleft or obscurely 3-5-lobed: fls. rosy pink, fragrant, 

 rather loosely paniculate. T TT r>

MALVAVISCUS (Greek, sticky mallow). Malvaceae. 

 Shrubs and tall herbs, a very few of which are culti- 

 vated for ornament. 



Usually hispid: Ivs. alternate, entire, dentate, angled 

 or lobed: fls. red, usually on axillary peduncles; petals 

 erect and connivent or spreading in the upper half; 

 column of stamens long and slender, exserted, only 

 partially fertile: carpels fleshy outside, connate into a 

 berry, later becoming dry and separating: involucel of

2312. Malvaviscus arboreus. ( X H) 



7-12 narrow bractlets. Species 10 or 12, sometimes 

 tree-like, in Trop. Amer., one reaching S. U. S. There is 

 one species of gardens, M. arboreus, known to the 

 trade as Achania Malvaviscus. It is a fine old green- 

 house shrub with erect scarlet fls., which resemble an 

 abutilon and never open widely. (Abutilon, however, 

 has no involucre.) 



The old Malvaviscus arboreus is one of the most satis- 

 factory house-plants. It is not subject to insects of any 

 kind, will stand a low temperature in winter, and blooms 

 both winter and 

 summer. When 

 pot -grown, the 

 plant is usually 

 about 2 feet 

 high, but out- 

 doors it makes a 

 strong branch- 

 ing growth, at- 

 taining 3 to 5 

 feet. The bright 

 scarlet flowers 

 remain a long 

 tune in perfect 

 condition. The 

 flowers open 

 slightly at the 

 top or not at all. 

 This circum- 

 stance gave rise 

 to the old name 

 Achania, which means "not gaping." The plant needs 

 a good light soil and thrives in a compost of fibrous 

 peat and loam. Propagated by cuttings. The culti- 

 vator need not fear the appearance of white grains on 

 the surface of the leaves, as they are a normal waxy 

 secretion of the plant. (James Vick.)

 loving plant. L H. B. 



MAMMEA (from mamey, aboriginal West Indian 

 name of M. americana). Guitiferse. A very small group 

 of tropical trees, of which M. americana is the only 

 species of horticultural value. The genus is allied to 

 the Malayan mangosteen (Garcinia Mangostana), but 

 differs in its two-parted valvate calyx, closed before 

 anthesis. 



Mammea is characterized by rigid, coriaceous Ivs., 

 frequently pellucid-punctate: peduncles axillary, 1-fld., 

 solitary or clustered; fls. polygamous; petals 4-6; 

 stamens numerous; stigma peltate or broadly lobed; 

 ovary 2-4-celled: fr. a drupe. Species perhaps a half- 

 dozen in the tropics of Amer. and Afr. but sometimes 

 defined to include only one.
