Gt. 1863:407; 56, p. 22. G.C. 1870:459; II. 12:437; III. 34:178. B.M. 5813. Gn. 12:352; 33, p. 527; 61, p. 40. R.H. 1872:170; 1911, pp. 62-3. A.G. 15:313. Mn. 8, p.61.—As few conservatories can make room for so large a plant, it is common to graft this species on dwarf varieties of D. rosea. The inflated and pointed fl.-buds (3—4 in. long) are very characteristic. It is not known whether the original plant collected by Roezl was found in wild or cult, surroundings. This species and the next are mostly cult, under glass if cult, at the N., but this species thrives in the open in Cent. Calif.; the others are grown outdoors in summer, and the roots stored in winter. Hybrids are reported between this species and D. excelsa. CH
