WOODHOt'SE AND TAYLOK. 129 



for three years. The brownish pods are slightly curved and 

 from 1 — 3 seeded. Not more than 3 pods are usually produced 

 on one raceme The average yield per plant from 500 plants 

 cultivated in the Botanic Experiment Area in 1911 worked out 

 at 49 grams per pla r 't. The weight of 100 seeds varies from 

 4*8 — 5 95 grams (mean 5*45 grams). 



Type 3a. 



An impure variety with greeny yellow seeds and a broad 

 brown band round the hilum was obtained from Kalimpong and 

 grown at Sabour in 1911. It was found to be extremely impure, 

 plants differing in having tawny or whitish hairs, stout, short, 

 upright or long twining upright branches and broader or narrower 

 leaves. In the majority of the plants the branches were very 

 numerous, long, thin, upright and twining at the ends. This is 

 variety 1 of Goodwin's list (13), in which it is stated to have the 

 finest flavour of the Darjeeling varieties. It was grown at 

 Sabour in 1911. (Plate III). 



Type 4. — " Lai Bi helmets" 



Basal portion of stem stout, upright, apical portion weak, re- 

 clining ; secondaiy branches long, weak, reclining ; some tertiaries 

 ascending. Stems, leaves and pods with tawny pubescence. 

 Flowers purple, 6 to 7 mm. long, sessile in short racemes. Pods 

 1*3 to 17 inches, 1-3 together. Seeds chocolate, 4 to 6 mm. long 

 by 3 to 4*5 mm. broad, elliptical slightly flattened only, hilum 

 slightly lighter chocolate. Germ yellow. Seeds contained 56 to 

 6*1 per cent, nitrogen and 15 - 6 to 17*3 per cent, oil in 1911. 



This differs from Type 3 only in its seed characters. The 

 red stains marking injuries to the stem of the type already 

 noticed in the case of Type 1 were also noticed in some plants, 

 and may perhaps be due to the same factor which produces the 

 dark colour of the seed coat in these two types. The average 

 yield per plant of nearly 1,500 plants cultivated in the Botanic 

 area in 1911 worked out at 53 grams per plant. The weight of 

 100 seeds varies between 4*41 and 6'5 grams (mean 553 grams). 

 In field cultivation it appears to be usually mixed with Type 3.
