According to Mueller, in Martius’ “ Flora Brasiliensis,” 
lic. Dipladenia polymorpha is a very variable plant; of which 
he describes four forms, to which may possibly be added a 
plant badly figured in Flore des Serres, vol. i. t. 74 (Aug. 
1846) under the name of D. vinceflora. It is widely 
distributed in Brasil, from the littoral province of Bahia 
to that of San Paulo, and is found also in those of Minas 
Geraes and Goyaz. Martius describes it as having purga- 
tive properties, and being known to the Portuguese as 
Purga do pastor. 
Tubers of var. tenuifolia were presented to the Royal 
Gardens, Kew, in 1896, by Mr. E. Hansen, Florist, of 
Mile End Road, London, which flowered in a stove in 
May, 1897, and again in Midsummer, 1898. 
Deser.—Var. tenuifolia. A very slender, glabrous,
