Continental establishments send out many hybrid Sciadocalyx, 

 crosses, I believe, between this species and digitaliflorum ; 

 gigantea, " Fl. des Serres," x. 975, is a hybrid between this 

 species and bogotense.

erianthum (Hanst. in " Linnaea," xxiv. 573, as Brachyloma 

 erianthum (fig. "Bot. Mag." 7907).— Colombia, up to 8,000 feet 

 elevation. This is the species which has been grown for many 

 years in our stoves under the name of " hirsutum." It was intro- 

 duced to cultvation by the late Mr. Bull. Vide "The Garden," 

 1883, ii. 264. Mr. Bull's son informs me that it was collected 

 and sent home by Mr. E. Shuttleworth in 1875, and that the 

 late Mr. Moore named it " hirsutum" It is not, however, 

 the hirsutum of Humboldt and Bonpland (vol. ii. tab. 189), 

 which is quite a different species that has apparently never been 

 introduced into England, and of which there are good specimens 

 in the Kew Herbarium. The flowers are solitary in the axils 

 or several from a short peduncle. The figure in " Bot. Mag." 

 is exaggerated in the colouring. This is one of the commonest 

 species of the genus in our stoves ; besides being one of 

 our most useful stove plants, it grows as well or even 

 better in a warm greenhouse (even throughout the winter), 

 as it then has sturdy short growth. It can easily be had 

 in flower all the year round if strong tops are continuously 

 rooted in the propagating frame ; they make much better 

 plants than the corms ; the old plants should be thrown away 

 after flowering, or when they get shabby. It is the " hirsutum " 

 of Continental catalogues, and some of the foreign establish- 

 ments advertise many hybrids from it. As far as I have 

 received these, they differ very slightly from the type, and show 

 no marked improvement, in fact nothing but a slight difference 

 in the colour of the flowers. 



hypocyrtiflorum (fig. "Bot. Mag." 5655).— Andes of Quito. 

 Very curious globular much swollen scarlet flowers on long 

 peduncles, which are solitary or twin in the axils of the 

 ovate-rotund leaves. A very striking plant. 



longlpeduneulatum (fig. "111. Hort." 287 as Kohleria lanata).— 

 Mexico. Whole plant densely silky-villose ; leaves ternate, elliptic, 

 nearly sessile ; peduncles erect, nearly as long as the leaves, 

 solitary or twin in the axils, 1 -flowered; calyx rather large, 

 segments oval, spreading ; flowers orange-scarlet, spotted in the 

 mouth, tube 1-1^ inch long. A very handsome species. 



pictum (fig. " Bot. Mag." 4431). — Colombia. A tall velvety hirsute 

 plant ; leaves reddish underneath ; flowers in a large terminal 

 head ; peduncles short, 1-3 in the axils of the small upper 

 leaves ; corolla orange and yellow, tube swollen, very contracted 

 at the mouth. A very fine species, rare in cultivation. 



Trianaei (fig. "Gartenfl." [1854], 82).— Colombia. Peduncles 

 thick, long, axillary, umbellate, and bracteolate at the apex, 1-4-
