them to the deptli y( 1 im-li with the same misture. If 

 the pans are then placed in a warm temperature with 

 bottom heat, every piece will quickly de^'elop one or 

 more buds and grow into a young plant. March is per- 

 haps the best time for propagating. As soon as the 

 young plants are well rooted they should be potted 

 singly into small pots and grown along in a tempera- 

 ture of about 60°. By the end of May the plants may be 

 planted out, either in spent hotbeds or frames prepared 

 with a goodly proportion of leaf -mold mixed with the 

 soil, if fine pot plants is the ultimate aim ; or if grown 

 for cut-flowers only, they may be planted out in the 

 greenhouse benches about l."i in<*hcs apart, giving all

way for several years, when in 4 or 5 years' time they 



will make very fine specimens. 



Cult, by Edwakd J. Canning. 



The Bouvardias of florists do not represent any of the 

 type species. They are sports, hybrids, and other types 

 of variations. The Latin-form names in American 

 trade catalogues nearly all belong to these garden forms. 

 The species which are of most import to the horticul- 

 turist are mentioned below : 



A. Fls. in shades of red. 



B. Zvs. normally in S's (except, perhaps, on the 



branchlets), 



triphJUa, Salisb. (B. Jdcqnini, HBK.). Small pu- 

 bescent shrub, 2-6 ft. high ; Ivs. in S's or 4's (or oppo- 



BOWIEA 



— The genus Bouvardia was founded upon this species, 

 which was introduced into England about 100 years ago. 

 It is evidently the most important parent strain, al- 

 though it is probably not in cult, in its original form. 

 Figs. 251 and 2.')2 partake very strongly of this species. 

 In fact, Fig. 251 compares well in botanical characters 



(except less long-pointed Ivs.) with the early pictures 

 of B. triphijUa.

 and better grower : stems hairy : Ivs. hairy above : fls. 

 glabrous. Mex. R.H. 1851: 81. -Perhaps only a form of 

 the preceding. 



Other red-fld.3-lvd. species are: B.angustifdlia, QBK. 

 Lvs. lanceolate, revolute, glabrous above and fine-pu- 

 bescent below : branches nearly glabrous. Mex. B.hir- 

 tilla, HBK. Very similar : lvs. pubescent on both sur- 

 faces. Mex. B. scAbra, Hook. & Arn. Lvs. ovate, 

 short-stalked: fls. large, in dense clusters, pink ; stem 

 hairy. Mex. 



B. Zvs. opposite. 



Cavanillesii, DC. {B. multitlbra, Schult.). Hairy: 

 lvs. ovate-acuminate, broad at base, short-stalked, edges 

 hairy: fls. VA in. long, very slender, glabrous. Mex. 

 AA. Fls. yellow.

 elliptic, very short-stalked, ciliate : fls. very long,

BOWIEA(after J. Bowie, colIectorforKew). Liliiceoe. 

 A monotypic genus containing one of the most curious 

 plants in the vegetable kingdom. A round, green bulb 

 4-5 in. thick throws up yearly a very slender, twining 

 flower-stem 6-8 ft. high, with many compound, forked, 

 curving branches below, and numerous small green fls. 

 above. The St. is somewhat asparagus-like. There are
