We will iiiivv give details of another case of .segregation in Kewensis 

 (see p. 170). 



P. Kewensis f| was, as already stated, typical Kewensis in appear- 

 ance, except that the anthers were not quite at the top of the corolla 

 tube, and the styles were shorter than is usual. There was much bad 

 pollen. We lost the plant before we knew that there was anything 

 exceptional in its behaviour. Self-fertilized this plant gave two plants, 

 nos. ^ and f|. 



-^. Smaller plant than Kewensis. Leaves broadly ovate. Whole 

 plant covered with hairs, visible to the naked eye but short and 

 glandular. No meal. Flowers pale yellow, small, fiat and imbricate. 

 Thrum. Robust habit. 



■f|. Small plant, Hower stems (jnly ti inches high. Leaves narrow 

 ovate (as in verticiUatu) but only 3 inches long. Hairs as in ^s- 

 Flowers pale yellow, small, funnel-shaped. Pin. 



Both these plants were selfed ; the seed of -fg failed tn germinate in 

 1913, but selfed again in 1914 it gave 



6 yellow thrum: 1 yellow pin. 



3 isabellina thrum : 2 isabellina pin. 



These plants varied from slightly hairy to modei'ately hairy. 



On selfing, || gave yellows and isabellina in the numbers 43 : 13. 

 The yellows were pale in tint and there were two shades of i.sabellina.
