Mammillarias, in common with other Cacti, run into many 

 forms. Some of these forms may be valuable to the horticul- 

 turist, and yet not sufficiently 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 Ameri- 

 can dealers: M.Brandi.M. brunea.M. drrhifera longispina 

 (see No. 66). M. Donati.M. filipendula.M. fuscata leona 

 (seeNos. 55,31). M. Lassomeri=M.. Lesaunieri(?). M. melo- 

 nacantha is an uncertain garden name. M. montana. M. 

 Nicholsoni='M.. Nickelsae (?). M. Rebsamiana.M. recurvens. 

 M. rigidispina. KATHARINE BRANDEGEE. 



MANDARIN OEANGE. See Citrus nobilis. 



MANDE VILLA (Henry John Mandeville, English 

 minister at Buenos Ayres ) . Apocyndcece. About 45 spe- 

 cies of tall climbers from tropical America with large, 

 funnel-shaped, 5-lobed fls. which are yellow, white or 

 rarely tinged violet. M. suaveolens has fragrant white 

 fls. and is cult, outdoors in S. Calif. Seeds are also pro- 

 curable in the East. The plant closely resembles Dipla- 

 denia, which see for culture. 



Generic characters: Ivs. opposite: racemes simple, 

 often 1-seeded, 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 or ovoid; lobes 5, 

 broad, twisted to the left; stamens fixed at the apex of 

 the tube, included; disk of 5 lobes or scales: ovary of 

 2 distinct carpels: stigma thick. 



suaveolens, Lindl. Sometimes called Chilean Jasmine 

 because of its climbing habit and large white fragrant 

 fls. Lvs. cordate, stalked, glabrous above, glaucous be- 

 neath; stipules pectinate: racemes with about 9 fls.
