MACODES 



MACODES (from iiiukos, length; on account of the 

 long labellum}. Orchiddcece. Contains but 2 or ;i spe- 

 cies of the habit of Anoectochilus, which see for culture. 

 Sepals and narrower petals spreading: laljelluin ventri- 

 cose, with 2 small lateral lobes and 2 calli inside, 

 turned to one side: column short, twisted in the oppo- 

 site direction, with 2 narrow, erect appendages. Ter- 

 restrial herbs, with few variegated petioled Ivs. at the 

 base, and small fls. borne in a long raceme. 



P6tola, Lindl. (AncectochUus Veitchidinus, Hort.). 

 Fls. greenish, inconspicuous: Ivs. ovate, 2-3 in. long, 

 reticulated with golden yellow veins. Java. R.B. 21:61.

MACROCHOBDIUU Etrictum, Beer, once advertised 

 by Pitcher & Manda, is referred byMez to ^ehmea bro- 

 meliafolia. Baker. See p. 28, Vol. I. It is Bromelia 

 tnelanantliii. Ker-Gawl, B. R. 9:766. The species is 

 characterized by white-scurfy Ivs., simple dense, woolly 

 spilses overtopping the foliage: fls. with yellowish green 

 caly.x and small exserted purple-black petals. S. Amer. 



MACB0SC£FIS (Greek, macros, long; skepo, to 

 cover). Asclepiadacew. A genus of about 8 species of 

 tall, tropical American climbers, of which M. elliptica, 

 Hort. Sander, was int. in 1899. Sander & Co. describe 

 it as "a new climbing stove-plant, with elliptic, light 

 green leaves, which, together with the stems, are densely 

 covered with soft, felt-like, yellow-brown hairs. The fls. 

 are in clusters, each flower about 1 in. in diam., resem- 

 bling in shape those of Hoya ortrnosa, and borne in simi- 

 lar bunches ; they are of a soft, velvety, rich brown color. 

 Every part of the plant, when bruised or pressed, is 

 strongly odorous." 



Generic characters are: Ivs. opposite, large, cordate: 

 cymes crowded: fls. white; calyx about 5-parted; corolla 

 tube thick; limb spreading: scales of the crown 5, in- 

 flexed under the throat of the fleshy corolla. 



MACKOTOMIA. Consult Arnebia. 



MACROZAMIA (Greek, lonri Zamia). CycadAcea;. 

 About .5-7 Australian cycads, which, like most of the 

 members of this order, make noble foliage plants for 

 private conservatories. They have the trunk and Ivs. 

 of Cycas, except that the piuniE have no midrib but are 

 more or less distinctly striate, especially on the under 

 side, with several parallel equal veins, the whole leaf 

 occasionally twisted in some species, but not constantly 

 so in any one. 



The genus is more nearly allied to Dioon and En- 

 cephalartos, from which it is distinguished by the fol- 

 lowing characters: Ivs. pinnate: scales of the female 

 cones peltate, the shield thickened, ascending, usually 

 produced into an erect, acuminate blade. Botanically 

 the group is very imperfectly understood. The writer 

 has followed Bentham's account in Flora Australiensis 

 0:250 (1873). 



Macrozamias are representative rather than useful 

 subjects, and not frequently seen. They combine poorly 

 in any scheme of plant and flower decoration; but as 

 single specimens, they always attract attention, and in 

 a grouping of similar subjects, or with aloes, agave and 

 yuccas they make an effective combination. Their cul- 

 ture is easy. Sandy soil, with charcoal to keep the soil 

 sweet, ordinary greenhouse temperature, plenty of wa- 

 ter duriii-' <)!■■ ;:r"\iii^' season, which corresponds to 

 oursuiir: ' in winter, are the essentials. 



At pr. 1/ - is the only name in American 



tradecM!;. _ I. -, tit wi,- other kinds were offered in 1893 

 and 189 J by .iohn f.:uil, and Pitcher & Manda. 



A. Pinna very narrow , often nearly terete: cones small, 



rarely above 4 in.: fr. very woolly. 



Paulo- GuiU«mi, Hill & Muell. (M.plumbsa.A. Mohr. ) . 



Trunk short : Ivs. 1-3 ft. long. R.H. 1877, p. 251. 



AA. Pinnce flat, inserted on the margins of the rachis, 



contracted at the base : cones 4-10 in., glabrous. 



B. Sachis of Ivs. usually raised longitudinally between 



the pinnw : cone scales much flattened. 



spiralis, Miq. Trunk short: Ivs. 2-4 ft. long: insertion 



of the pinnae mostly longitudinal: points of the scales 



usually short. G.C. III. 13:74.- Jf. cylindrica.C. Moore. 



MAGNOLIA 



is a distinct species according to Index Kewensis, but 

 Bentham considered it a doubtful variety of M. spiralis, 

 being smaller, with the narrow foliage nearly of M. 

 Paulo-Guilielmi, but with a glabrous trunk and more 

 terete rachis. 



BB. Bachis of Ivs. very flat between the pinnae and often 

 broad: cone scales very thick. 

 Miqu6Ui, DC. Cult, abroad. John Saul advertised Af. 

 Macqui, presumably a typographical error either for 

 M. Miquelii or else M. Macleayi, Miq., which = if . 

 spiralis. 



AAA. Pinnce inserted by their broad base along the cen- 

 ter of the upper surface of the rachis, scarcely 

 siparated by a very narroiv line : cones large, 

 pnhi'srt'nt, the scale points broad and often 

 ,,ciuvtd. 

 Peroffskyana, Miq. (M. Perowskidna, F. Muell.).

MADIA (Madi, the Chilean name of the common spe- 

 cies). Oompdsitie. Nine species of yellow-fld. herbs 

 confined to the western part of the American continent. 

 Their fls. are remarkable for closing in the sunshine, 

 and opening in the morning or evening. They are all 

 called Tarweeds from their glandular, viscid, heavily-
