LINARIA 369 



L. vulgaris, "whicli tip to the time of the introduction of L. repens had been 

 a fairly constant plant, now assumed great variability, not necessarily in 

 the direction of L. repens. This will be noticed under L. vulgaris. 



Seeds of the first grovip of hybrids were planted ; they yielded plants still 

 nearer to L. repens. and indeed might have passed as such. Seeds of this 

 second generation, however, yielded plants in which the L. v^dgaris parentage 

 was more evident. L. vulgaris pollen had been kept from them. See Annals 

 Bot. X. (Dec. ji^gS) 622. 



At Pangbourn a large series of hybrids have also been found. 

 Specimens were distributed by me through the Bot. Exch. Club in 

 1892, &c. 



xi. Baxierii occurred with the other hybrids at Didcot in 1896. 

 L. repens occurs in Bucks, Hants, and Oxfordshire.

L. vulgaris is a very striking feature in our vegetation, and its bright 

 yellow flowers are a general favourite. It is too fi'equent to need an 

 enumeration of localities. 



Linaria vulgaris x repens. * Found at Sulham, near Eeading, 

 August, 1877. Two varieties growing plentifully and near together, 

 but quite distinct, on chalk ; one kind, white-striped with lilac and 

 yellow throat, the other white, except yellow throat ; the sepals of 

 both shorter than the spur, and generally wrinkled with a ring, but 

 some with a wrinkled border,' Miss S. M. Payne in Bot. Exch. Cnib, 1877-8. 



Miss Payne's specimens are much nearer to repens than to L. vulgaris. 



For further description of hybrids of L. vulgaris and L. repens see 

 a note under the latter species. 



Under L. repens the fact Avas noted that, after hybridization of 

 L. vulgaris and L. repens had gone on for some time, L. vulgaris, in which 

 no trace of L. repens parentage occurred, exhibited a great degree of 

 variability. 



A considerable number of forms have been seen on railway banks at 

 Didcot, Eeading, and near Oxford. These include — -/. concolor, in which 

 the flowers are of a uniform pale yellow without a dark orange palate ; 

 /. bicolor, in which the corolla is of a very pale opaque cream-colour 

 and with a conspicuous orange-coloured palate. Each of these occurs 

 in narrow-leaved and in broad-leaved forms.
