PALESTINE WILD PEA WITH COMMERCIAL TYPES. 431 



The following is a brief history of the cross : 



f The cross gave one seed only. This was round, greenish in 

 colour, and with no black hilum. 



The hybrid plant grew about 2 feet in height, was of normal 

 growth and not umbellate, the foliage was rather small with some

self-coloured (the standards being pink with wings dark purple). 

 This plant produced five seeds, which were much like those of the 

 parental Palestine seeds in colour, but varied in size. 

 No fusciation in stem. 



The nVe seeds were sown and all germinated, and grew suffi- 

 ciently to show that they varied in character. Four of them, 

 however, did not produce a single seed, and only one could be con- 

 Fo. { tinned beyond F 2 . The plant which matured was of fairly strong 

 habit of growth, not umbellate, the leaflets had very little trace 

 of serration, and the blooms were bi-coloured. No fascia tion in 

 stem. The seeds were small, brown mottled, with black hilum. 



v^ 



The seeds from this plant were sown the next year, the new types Nos. 1, 

 3, 4, and 5 appearing in F 3 and Nos. 2 and 6 in F 4 . 



New type No. 1. (PI. 15. fig. 4 G.) 



A dark bi-coloured flowering form of the parental umbellate type, appear- 

 ing- in F 3 . Previously, so far as I am aware, this dark-flowered umbellate 

 form did not exist, the only umbellate forms hitherto known being (1) a 

 white-flowered form (Pisum arvense umbellatum, PI. 15. fig. 4 H), and (2) a 

 rose- and white-flowered form (Pisiim arvense umbellatum, PI. 15. fig. 41). 



The seeds of this new type (PI. 17. fig. 13) also differed from those of the 

 parental umbellate form (PI. 17. fig. 10), and of the rose- and white- 

 umbellate form (PI. 17. fig. In). It will be noticed that the seeds of this 

 new type are small and have a black hilum. 



Apart from the colour of the blooms and the seed, the hybrid much 

 resembles the parental umbellate form. 



New type No. 2. (PI. 16. fig. 5.) 



This is the nearest approach in general appearance I could find to an 

 umbellate form of the Palestine Pea (although the flowers were white), and 

 appeared in F 4 from New type No. 1. It was much weaker in growth than 

 the parental umbellate form. The chief characters were as follows : 



Flowers white. 



No serration in the leaflets. 



No colour in axils. 



Seeds smaller than the parental umbellate or crown-flowered Pea, but 

 with a black hilum. (PI. 17. fig. 10.)
