Mammillarias, in common with other cacti, run into many forms. 

 Some of these forms may be valuable to the horticulturist, and yet 

 not 8ufficientl.v distinct to warrant the giving of definite botanical 

 names. The following names, not accounted for in the above review, 

 are offered in the catalogues of .\inerican dealers: M. Brdndii. — M, 

 brunea. — M. cirrhlfcra longispina (see No. 75). — M. Dondtii. — M. 

 filipindula. — M. fuschta Ledna (see Nos. 35, 62). — A/. I-Ms.^dmeri=^ 

 M. Ixsaunierif? j. — M. mdondcanlha is an uncertain garden name. 

 — M. moiUana. — M. yt€hoUonii^=^l. Nicltels£e(?). — M, liebsami- 

 ana. — M. recurteng. — M. rigiflispina. 



The following species, mostly recently described, have appeared 

 in foreign publications. None of them is being grown in Amer. : 

 M. Boedekeriana, Quehl. — M. bomhycina, Quehl. — M. campfotricha, 

 E. Dams. — M. collina, Purpus. — ,V/. cordlgera, Heese. — M. Emskoet- 

 Uridna, Quehl. — M. Joosensiana, Quehl. — M. Knippelinna, Quehl. 

 — M. Miindtii, Hchnm. — M. napina, Purpus. — M. pilisvina, Purpus. 

 — J/. TitmoKiiiHima, Quehl. — M. Ruestii, Quehl. — M. Hdrtorii, Pur- 

 pus. — M. Seidelitina, Quehl. — M. trichacdnlha, Schum. — M. uni- 

 »eta. Quehl. — M. Verhiertinrui, Boedeker. 



The following species are likely to appear in the trade at any 

 time: 3/. ceratitef, Quehl. This species has been associated with M. 

 Delstiana and M. durangensis, but it seems to be very close to M. 

 conoidea. It h.is not yet been intro. into American trade. — M, 

 Dtlittiana, Quehl. .Sts. club-shaped, about 3 in. high: tubercles 

 grooved on the upper side: fls. large, pale yellow. Mex., soine- 

 timea credited to Calif. — M. durarifjenaig, Runge. Very beautiful 

 specie* with small central fls. Does not grow well in cult. — M. 

 pgeudoperbeUa, Quehl. A species recently intro. into Ku. Very 

 close to M. elegans. Not yet cult, in Amer. i ^ Rose t 



MANDARIN ORANGE: Citrus nobilis var. dehciom. 



MANDEVILLA (Henry John Mandeville, British 

 mini.ster at Huenos Ayres). Apocynacea-. Tali climbers 

 from the wanner parts of America, with large fiinnel- 

 shapefi, .T-lobcd flowers which are yellow, white or 

 rarely tinged violet. 



Wixxiy plants: Ivs. opposite, penni veined: racemes 

 simple, often 1-sided, loose, dense or reduced to 2 or 3 

 fls.; calyx 5-parted, with several glands inside at the 



base or 5 scales; corolla-tube cylindrical, funnel-shaped, 

 or ovoid; lobes .5, broad, twisted; stamens fixed at the 

 apex of the ttibe, inehuled; disk of .3 lobes or scales; 

 ovary of 2 distinct carju'ls; stigma thick: follicles erect 

 or divergent, incurved and more or less cohering at 

 apex, terete or angled. — Species .'50 or more, Mex. to 

 ArgiMitina, but some of them probably to be referred 

 to lOchites or elsewhere. The species are little known 

 as cult, subjects. The plants resemble Dipladenia, 

 which see for cult. 



suaveolens, Lindl. (Echlles funifurmis, Gris., not 

 Veil.). iSometmies called Chilean jasmine because of 

 its climbing habit and large white or blush fragrant fls.: 

 Ivs. eonlate, stalked, glabrous above, glaucous beneath; 

 stipules pectinate: racemes with about 9 fls. each 2 in. 

 across. Argentina. B.R. 26:7. B.M. 3797. G.C. III. 

 2:817. P.M. 16:289. R.H. 1S4.'5:167; 1913, p. 424. 

 J. II. III. 48:413. G. 29:443. 8ome of the foregoing 

 portraits may represent the following species, as the 

 two have been confused. — Characterized by a pale, 

 fleshy pectinate ring between the base of the calyx and 

 corolla. 



Tweedieana, Gad. & Stapf. Much like M. suaveolens, 

 dilTering in having glabrous branches, long-acuminate or 

 almost caudate Ivs.j longer petioles, lanceolate bracts, 

 more fragrant fls. with lanceolate sepals, brilliant white 

 corolla-limb and green tube. Probably Argentina.

 MANDRAGORA (name used by Hippocrates, said 

 to signify that the plant is hurtful to cattle). Solatia- 

 cese. Mandrake. Old medicinal herbs. 



A genus of three or four species, one of which is sup- 

 posed to be the dudaim mentioned in Genesis, chapter 

 30. In America the name mandrake is appUed to the 

 mayapplc. Podophyllum peltalum, but the mandrake 

 of history is a plant with a large spindle-shaped root 

 which was supjjosed sometimes to 

 become forked and resemble the 

 lujman form. In this condition it 

 was used as an aphrodisiac. The 

 plant was also called love-apple, 

 and many superstitions about it 

 still survive. The old herbals 

 abound in fanciful pictures of the 

 m:uidrake, one of which is repro- 

 duced in Fig. 2317. M. officinarum 

 may be cultivated in the hardy 

 border for its folk-lore interest. 

 iV/. mUumrtalis is supposed by 

 some to be the true mandrake. 

 Both are natives of the Mediter- 

 ranean region. M. caulescens is 

 found in the Himalayas. The 

 mandrakes are allied to belladonna 

 ( A t r o p a ) and have poisonous 

 qualities. 



Mandragoras are mostly stemless perennial herbs 

 with thick roots and large, stalked, wavy-margined Ivs., 

 the later ones being usually narrower and entire, and 

 rather large fls. varying from whitish through bluish 

 violet and purplish .shades: fls. purple, bell-shaped, 

 about ."j-cut, netted-veined and borne in clusters among 

 the tufted Ivs.; calyx deeply .'i-cut; sinus of the corolla 

 induplicate between the lobes; stamens .'j:fr. a globose 

 or oblong juicy berry. 



officinarum, Linn. (M. officinalis, Mill. Alropa Man- 

 ilriiyiirn, Linn.). Mandkake. Lvs. ovate, the first ob- 

 tusi', the others acuminate: calyx-teeth lanceolate, as 

 long as the oblong berry. R.H. 1897, p. 131.

MANDRAKE in America means the mayapple (Po- 

 dophyllum) but the mandrake of history is Mandra- 

 gora, above.
