THE SNAPDRAGON AND LINARIA FAMILY. 531 



connate, halberd -head -shaped leaves, now in cultivation at 

 Kew, the exserted style is separated from the anthers by the 

 swollen top of the slip- 

 per, as shown in the ac- 

 companying engraving ; 

 and Professor Oliver 

 kindly informs me that 

 Hildebrand describes a 

 similar contrivance to in- 

 sure protogyny in C. pin- 

 nata in the ' Botanische 

 Zeitung' (1867), with il- 

 lustrations. This contri- 

 vance is analogous to 

 others which have been 

 repeatedly observed in 

 species of Agave, Prim- 

 ula, and in most Compo- 

 sites. Gaertner observes, 

 in his work on hybridism 

 previously alluded to : 

 " Of all genera, Calceola- 

 ria seems to present the 

 greatest tendency to hy- 

 bridise ; the pure Species Calceolaria Pavonii. a, anther ;*, style;

lity, and their hybrids are 



all fertile and disposed to fresh admixture; even the fruticose Cal- 

 ceolarias unite with the herbaceous section or C. plantaginea 

 (1826) (see Herbert's 'Amaryllidacese,' p. 363, and 'Bot. Mag.,' 

 t. 2805). C. arachnoidea (see ' Bot. Mag.,' t. 2874) has woolly or 

 cobweb-like lanceolate leaves, and bears conspicuous panicles of 

 bright purple flowers. C. rugosa (see 'Bot. Mag.,' t. 2523) is one 

 of the progenitors of our dwarf, yellow, bedding race, and bears 

 rather dense panicles of small golden flowers. The leaves are 

 much netted, bright green above and tawny beneath (see 

 also C. integrifolia, 'Bot. Reg.,' t. 744). C. corymbosa (see 'Bot. 

 Mag.,' t. 2418) is one of the most showy of the Chilian species, 

 and bears rather lax panicles of long-pocketed, orange-yellow 

 flowers. I can remember seeing these long-flowered, slender- 

 habited forms in cottage - windows fully twenty years ago. 

 Other interesting old species may be found in Sweet's ' Flower 

 Garden,' Paxton's ' Magazine of Botany,' and the ' Botanical 

 Register' or Loddige's 'Cabinet.' C. pisacomcnsis (see 'Bot.
