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 olfered in the catalogues of Ameri- 

 can dealers: M. Brandi.—M. bninea. — M. cirrhifera longispina 

 (see No. 66). — M. Donati.—M. fUipendula.—M. fuscata leona 

 (see Nos. 55,31).— Jf. Lassomeri=M. Lesaunieri (!).— Jlf. melo- 

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

 Nicholsoni=M.. Nickelsas (?).- Jlf, Rebsamiana.—M. recurvens.

MANDARIN ORANGE, See Ci/nis nobilis. 



MANDEVlLLA (Henry John Mandeville, English 

 minister at Buenos Ayres). Apocyndceie. About4j spe- 

 cies of tall climbers from tropical America with large, 

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

 rarely tinged violet. M. suni-eolens has fragrant white 

 fls. aud 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 Hs.: 

 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. 



suav^olens, Lindl. Sometimes called Chilean Jasmine 

 because of its climbing habit and large white fragrant 

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

 neath ; stipules pectinate: racemes with about 9 fls.
