(14) Hybrid Nicotianas. These are hybrids 

 produced by crossing six or more different species 

 of Nicotiana. "Many of the new hybrid varieties 

 are only obtained after several thousand crossings, 

 under all conditions which seemed to promise 

 success; but now I have perennial varieties with 

 glaucous green foliage, edged and mottled with 

 white, bearing pink blossoms in cymes two or 

 three feet across with from five hundred to two 

 thousand or more blossoms in each cyme. Most 

 of these hybrids are readily propagated from root 

 cuttings or slips; none of them ever bear any seed; 

 all are unusually hardy." 



(15) Begonia-Leaved Squash. "A mammoth 

 squash which produced abundant crops for stock 

 feeding and has bright golden variegated leaves. 

 The unusual leaf variegation appeared four years 

 ago [1889] on a single vine, and by selection has 

 become so fixed that at least 95 per cent, are varie- 

 gated. The form, size, and uniform appearance of 

 the squashes has also been very greatly improved." 



(16) New Potatoes. Two varieties are de- 

 scribed as being the best of several thousand 

 seedlings that have been tested for five years. One 

 is a long, nearly cylindrical, smooth, white seed- 

 ling of the Burbank; the other is a short, flatish, 

 oval, light colored potato with a russet coat, from 

 a cross between the old "Chile" or "Bodega red"
