MALPIGHIA 



(Mareello Mal- 

 pighi, 1628-1693, 

 distinguished na^ 

 turalist at Bolo- 

 gna, who wrote on the anatomy of plants). Malpig- 

 hiacex. Trees and shrubs, sometimes grown under 

 glass for ornament, but known mostly from the Barba- 

 dos cherry, cultivated in the American tropics. 



Leaves opposite, short-stalked, glabrous or tomen- 

 tose, entire or spiny-toothed : fls. axillary and terminal, 

 clustered or corjanbose, rarely solitary, red, rose or 

 white; calyx with a pair of thick glands on the back of 

 some or all the 5 sepals; stamens 10, all perfect, the 

 base of filaments glabrous; ovary 3-celled; styles 3, dis- 

 tinct: drupe 3-pyrenous, not winged, the stones with 

 3-5 crests or wings on the back. — Species 30-40 in 

 Trop. Amer., extending as far north as S. Texas. Small 

 describes 29 species in N. Amer. Fl. XXV, p. 1.52 

 (1910). 



glibra, Linn. Barbados Cherry. Fig. 2308. Shrub, 

 6 ft., glabrous, the br.anches .slender: Ivs. ovate to 

 elliptic, entire, usuallj' pointed, having a few biscuspi- 

 date hairs which disappear early: umbels 3-.5-fld.; fls. 

 J^in. across, rose-red, the petals erose or fringed: drupes 

 red or scarlet, about the size of a cherry, acid, with 

 thin skin, used for jam and preserv'cs; seeds large, 4- 

 angled. S. Tex;is to N. S. Amer.; W. Indies. B.M. 813. 

 — Widely planted in tropic.s, and offered in S. Fla. Prop, 

 by cuttings, and seefis geiTninate readily. 



mexic^a, .Tuss. (M. giuutalajarcnsis, Rose). Lvs. 

 ovate to obovat<vlanceolat€, either acute or obtuse, 

 imbescent or tomentose: oymes one-third to one-half 

 length of lvs.; fls. purplish, aboiit Min. across; sepals 

 ovate to ovate-lanceolate, densely pubescent: fr. nearly 

 globose, red. Mex. — Offered in S. Calif. 



coccigera, Linn. Lvs. oval or ovate to suborbicular, 

 obtiise. rounded or emarginate, mostly sinuate-dentate, 

 glabrous at maturity, shining above: cymes "hort^ 

 pe<luncled; fls. pink; sepals oblong or ovate-obiv ng. 



2307. Malope trifida. ( X H) 



with large gl.ands: drupe nearly globo.se, red. W. Indies. 

 — Listed in S. Fla. as a good holly-like plant useful for 

 dwarf hedging. L. H. B. 



MALUS (Creek for apple). Rosacesp. Apple. Most 

 botanists prefer to unite the apple and pear in the one 

 genus Pyrus; this is the method of Bentham & Hooker 

 in "Cenera Plantarum," and of Focke in Engler & 

 Prantl's "Pflanzenfamilien," although the recent 

 excellent work of Schneider, "Handbuch der Laub- 

 holzkunde," keeps them distinct, as do some of the 

 recent American authors. The evident botanical 

 (li.stinctions between the two groups are slight, appar- 

 ently not suHicient for easy or clear determination by 

 the unprofessional student. These differences lie in 

 the usual presence of grit-cells in the fruits of Pyrus 

 and their usual absence in Malus; in the hypanthium 

 of the former being nearly closed by a cushion, and in 

 the latter free or open; in the cavity about the stem of 

 the fruit in Malus, a contrast which does not hold in 

 Pyrus; and in the styles of Pyrus being distinct or 

 nearly distinct, whereas in Malus they are more or less 

 united. The different degrees of union of the styles 

 has been made a basis for distinguishing the named 

 varieties of apples among themselves, anfl the character 

 does not appear to be important enough to be made 

 the basis of generic separation. It is not impossible 

 that the pears and apples may have had a different 

 phylogenetic origin, but this fact itself would not be 

 sufficient in generic description. — The apples are small 

 trees and bushes, of some fifteen to twenty species in 

 the North Temperate Zone. In this Cyclopedia, the 

 cultivated apple species are described under Pyrus; 

 the names of the leading species under Malus are as 

 follows : 



M. sylvestris, Mi\l. = Pyrus Malus. 



M. prunifolia, Borkh. = P. prunifolia. 



M. baccata, Borkh. = P. baccata. 



M. coronaria, Mill. = P. coronaria. 



M. ioensis, Brit. = P. ioensis. 



M. Soulardii, Brit. = P. Soulardii. 



M. angusiifnlia, Michx. = /'. angtislifolia. 



M. Halliana, Koehne = P. Halliana. l H. B.
