204 GENERAL REVIEW. 



Boliviensis and an unnamed species. Although a hybrid, it 

 seeds freely, its progeny being very variable in colour ; indeed, 

 I have seen red, magenta, carmine, rose-yellow, lilac, vermilion, 

 and pure white forms produced from the same seed-pod.

B. octopetala, recently reintroduced into our gardens by M. 

 Frcebel & Co. of Zurich, is the largest-flowered species in the 

 genus, and may possibly be induced to hybridise with other 

 species (see 'Flor. des Serres,' 1874, p. 25). 



The above species, and earlier 'hybrids, have been made 

 the parents of innumerable very beautiful and richly-coloured 

 forms, both in our own gardens and also in those on the Con- 

 tinent. Hybrids between the glowing scarlet -flowered and 

 compact-habited B. Frcebeli (a new Andean tuberous-rooted 

 species sent by M. Roezl to MM. Froebel of Zurich, about 

 1874) and the large-flowered B. octopetala have been obtained 

 by M. Froebel, so that we may expect a new race rivalling 

 those hybrids now in cultivation. 



M. Schmidt, of Lyons, has obtained a race of free-flowering 

 varieties, the result of cross-breeding between B. insiguis, a 

 well-known perpetual bloomer, and some of the tuberous- 

 rooted kinds. The colours of these hybrids vary from white 

 salmon and pink to a rich carmine. Messrs Veitch & Son 

 also obtained several seedlings between their new tuberous- 

 rooted varieties and B. insignis, but they were discarded as not 

 being superior to other kinds. B. hybrida, " Montblanc," is a 

 hybrid between B. Pearcei and B. discolor (see ' Revue Hort.,' 

 1876, p. 67). 



B. Spinksii (Chiswicfc). This is a hybrid between B. 

 Pearcei and B. Boliviensis ; the leaves are like the former, 

 and the flowers of the same shape as the latter, but of a yellow 

 colour tinged with rose. 



B. ascotiensis is rarely seen in English gardens, although com-
