MAMMEA 



1975 



from the axis at maturity. — Some 7{)-S() or more species, 

 in Amer. ami S. Afr. Tlio garden species are perennials 

 of easy cult., blooming in the hot weather. 



A. Fit. while, with eye. 



hypomadanun, Spragvie. Shrubby, sometimes rcaeh- 

 inp; 10 ft., slender-hranehed, free-llowcring: Ivs. variable, 

 usually 3-lobed and more or less toothed, sparsely 

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

 eye, about 1 • ^ in. arross, axillary, solitary or 2 or 3 

 together; petals obliquely obovate, refuse; ctdyx-lobes 

 ovate, acuminate and ciliate; bractlets 3, spatulate- 

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

 295 (a.s Malra eapensis). — This species was founded as 

 late as 190S, although in cult, in Great Britain for a 

 century under other names, ;is M. capense, M. virgatum, 

 M. grossularisfolium. Prop, by cuttings under glass in 

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

 lowing season. 



AA. Fh. colored. 



capense, Garcke {Mdlva capenns, Linn.). Shrubby 

 and branchy, sUghtly viscid: Ivs. ovat<^oblong, some- 

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

 on axillarj- peduncles, purple; involucel variable in size, 

 the bracts lanceolate to ovate-lanceolate and shorter 

 than the ciliate calyx-lobes: carpels glabrous. S. Mr. — 

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

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

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

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

 also Kitaibelia Lindemuthii, p. 1738. It is doubtful 

 whether .1/. capense is in cult.; the plants passing under 

 this name may be M. hypomadarum.

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

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

 solitarj', brick-red; calyx-lobes ovate and spreading; 

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

 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 cocclnea, Nutt. Cristaria 

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

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

 pedately .3-5-partea or -divided, the narrow divisions 

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

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

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

 scarlet fls.

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

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

 terminal raceme, blooming until killed by frost; 

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

M. GUlieitii, Baker. More or leaa procumbent: Ivs. hair>', 

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

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

 florum, Gray fM. splendidum, Kell. ), in S. Utah to 8. Calif. Shrub, 

 becoming 12 ft. or more, gray-tomentose: Iva. joundish and mostly 

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

 rather loosely paniculate. T H R 



MALVAVISCUS (Greek, sticky mallow). Malvdcea: 

 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, usuidly on axillary peduncles; petals 

 erect anrl connivent or spreading in the upper half; 

 column of stamens long and slender, exserted, only 



Eartially fertile: carpels fle.shy outside, connate into a 

 erry, later becoming dry and separating: involucel of 



2312. Malvaviscus arboreus. ( X H) 



7-12 narrow bractlets. — S])ecies 10 or 12, sometimes 

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

 one species of garilens, M. arboreus, kno\vn to the 

 trade as Achania Malvari.'tcus. It is a fine old green- 

 house shrub with erect scarlet fls., which resemble an 

 abutilon and never open widely. (Abutilon, however, 

 luis no involucre.) 



The old Malvansciis arboretis is one of the most satis- 

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

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

 both winter and 

 smnmer. When 

 pot -grown, the 

 plant is usually 

 about 2 feet 

 high, but out- 

 doors it makes a 

 strong branch- 

 ing grovrth, at- 

 taining 3 to 5 

 feet. The bright 

 s c ar let flowers 

 remain a long 

 time in perfect 

 condition. The 

 flowers open 

 shghtly at the 

 top or not at all. 

 This circum- 

 stance gave rise 

 to the old name 

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

 a good light soU 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.) 



arbfireus, Cav. (Achania Malvaviscus, Swartz). Fig. 

 2312. Tall shrub: Ivs. alternate, mostly 3-lobed, acimii- 

 nate, heart-shajjed at the base, toothed: fls. convolute in 

 the bud, scarlet, never fully expanding; bractlets erect 

 and narrow. S. Amer. B.M. 2:305. L.B.C. 12:1155.— 

 Cult. outdoors in S. Fla. and S. Calif. 



mollis, DC. (Achania tndllis. Ait.). Shrub, recom- 

 mended for hedges in Calif.: Ivs. cordate, soft and 

 tomentose, obscurely 3-lobed: fls. scarlet, with some- 

 what spreading bracts. Mex. to Colombia. B.M. 2374. 



Drummondii, Torr. & Gray. Tall perennial, to 6 ft. 

 or more, somewhat tomentose, erect, simple or 

 branched: Ivs. round-cordate, mostly 3-lobed, as broad 

 as long: fls. vermilion-red, 1 in. long, on axillary pedun- 

 cles; bractlets of involucel narrow-spatulate; column of 

 stamens becoming exserted: fr. berry-like, red, finally 

 separable into carpels. Fla. to Tex. and S.— A good sun- 

 loving plant. L. H. B. 



MAMMEA (from mamey, aboriginal West Indian 

 name of M . americana). Guttiferse. 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 mangostcen (Garcinia Mangostana), but 

 differs in its two-parted valvate calyx, closed before 

 anthesis. 



Mammea is characterized by rigid, coriaceous Ivs., 

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

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

 stamens numerous; stigma i)eltate 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.
