MANDARIN OEANGE. See Citrus nobUis. 



MANDEVtLLA (Henry John Mandeville, English 

 minister at Buenos Ayres). Apocy}idci:(i>. About 4.5 spe- 

 cies of tall climbers from trotdcal America w^ith large, 

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

 rarely tinged violet. 31. snrnwnhns 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. 



stiav^olens, 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.
