432 MR. A. W. SUTTON ON RESULTS OBTAINED BY CROSSING 



New type No. 3. (PI. 16. fig. 6.) 



This plant is perhaps the most remarkable of all, being a non-umbellate 

 form of a white flowering Pea, which resulted from a cross between the 

 Palestine Pea (a coloured flowered, brown-seeded type) and the Pisum satinim 

 itmbellatum (white-flowered, white-seeded umbellate form). It appeared in F 3 . 



We have here, therefore, an instance of two types, so different from each 

 other that they might be looked upon as specifically distinct, uniting to give 

 a fertile hybrid. Crosses may, and probably have been made previously 

 between types of the Garden Pea (Pisum satinim) and the Field Pea (Pimm 

 arvense), but I may confidently say that there is no variety of Pea in com- 

 merce to-day, either amongst the Field Peas or culinary Peas, which has 

 arisen in such a manner. 



The chief characters were as follows : 



Fairly strong habit of growth. 



Flowers white. 



Non-umbellate. 



Absence of serration in leaflets. 



Absence of colour in axils. 



Seeds yellow, with small black hilum. (PI. 17. fig. 17.) 



New type No. 4. (Plant not illustrated.) 



This plant somewhat resembled the last in growth, but differed in the colour 

 of the bloom. It appeared in F s . The chief characters were as follows : 

 Non-umbellate. 

 Fairly strong habit of growth. 

 Flowers bi-coloured. 

 Absence of serration in leaflets. 



Seeds, brownish in colour, mottled, with small black hilum. 

 (PI. 16. fig. 18.) 



New type No. 5. (PI. 16. fig. 7.) 



This plant is really a more robust and stronger growing form of New type 

 No. 4, and also appeared in F 3 . The chief characters were as follows : 

 Non-umbellate. 

 Strong habit of growth. 

 Flowers bi-coloured. 

 Absence of serration in leaflets. 



Seeds much paler in colour than last named, and with a well-marked 

 hilum. (PI. 17. fig. 19.) 



New type No. C. (PI. 16. fig. 8.) 



This plant is practically identical in all characters with the parental 

 umbellate type (PI. 15. fig. 2C), except that the seeds (PI. 17. fig. 20) are
