(2) S. Maglia x a Chilian cultivated variety (Francesa Col.) : sown 

 March 28 ; first flower opened August 3 ; taken up November 11 [/3]. 



This seedling entirely resembles S. Maglia in general appearance, and 

 would at first sight be taken for that plant. It has dark branching stems 

 and sparse, firm foliage, which is subject to disease about equally with 

 S, Maglia. The flowers are scanty, the trusses small. The corolla is 

 large, of mid- violet colour, with white tips (very like that of No. (1) seedling 

 in size and colour) — one truss had pure-white flowers — the stamens strong, 

 and straight, similar to those of No. (1), but not having so much or so 

 fertile pollen ; the style is longer, projecting beyond the stamens like that 

 of S. Maglia. This plant had no berries, although every flower was 

 pollinated. The tubers are in colour violet (No. 3 91, 1 and 2), like those 

 of S. Maglia, of good shape, rounded oblong, smaller at the "rose" 

 end than at the base, with white eyes. They were all found near the top 

 of the soil in the pot, and are entirely free from disease, although the 

 leaves were affected. 



It is difficult to get seed from S. Maglia. Again this summer, 

 although on one of my plants fifty-five berries set and swelled (due to many 

 different crosses) only five of them have contained mature seed— one seed 

 in each. 



In 1907 I also effected a cross of S. " etuberosum" x 'Duchess of 

 Cornwall,' and append brief notes of the fourteen seedlings resulting. The 

 two dates at each are those of flowering (first flower open) and of taking 

 up. They were all sown on March 19, 1908 : — 



1. July 15, September 15 : White flower, would not " self " ; fifty 

 tubers, same as those of S. " etuberosum" three slightly diseased; 

 19f oz. 



2. July 16, October 31 : Flower almost white, dark lavender rays at 

 back, downy ; sepals greenish, downy ; tips green ; three tubers, small, 

 round, violet-black. 



3. July 18, November 10 : Flower pale mauve ; back of petals rich 

 mauve, rays hirsute ; sepals brownish, hairy, tips brown ; eleven tubers, 

 red (No. 170, 3 ; or 105, 4) ; deep eyes. 



4. July 19, September 28 : Flower lavender ; back of petals mid-violet ; 

 large anthers ; little pollen ; sixteen tubers, round, white, five slightly 

 diseased ; deep eyes ; coarse. V ery strong plant. 



5. July 30, September 28 : Flower uniform mauve ; small truss ; 

 nine tubers (besides five largest diseased), round, oblong, white ; fine ; 

 second growth started, one bud half inch long. (Too long in ground.) 



6. August 1, September 28 : Flower white, tinged creamy-pink ; six 

 tubers, oblong, white, small at end of runners ; foliage diseased, 

 September 18.

8. August 4, not noted : Flower pale carmine-mauve ; eleven tubers, 

 fine, kidney form, white, flesh yellowish, two diseased. 



9. August 5, September 23 : Flower nearly as S. " etuberosum," very 

 pale mauve at centre, rest nearly white ; pollen abundant ; one small 

 coloured tuber forming ; foliage destroyed by disease September 15.
