DALBERGIA SEVERNENSIS Berry 

 Plate LXXVI, Fig. 3 



Dalbergia severensis Berry, 1911, Bull. Torrey Bot. Club, vol. xxxviii, p. 

 407, pi. xix, fig. 2. 



Description. Leaflets of rather small size, oblanceolate in general out- 

 line, with a markedly emarginate apex, gently curved sides and narrowly 

 pointed base. Length about 5 cm. Maximum width, in the middle part 

 of the leaf, about 1.5 cm. Margins entire. Texture subcoriaceous. 

 Petiolule wanting. Midrib stout below, thin above. Secondaries thin, 

 five or six pairs, diverging from the midrib at angles of 45 or less, the 

 lower ascending, the upper curved, all eventually camptodrome. 



This handsome form is clearly distinct from related forms and is 

 identical in its characters with the fossil leguminous leaflets usually 

 referred to the genus Dalbergia. The modern species number about four 

 score distributed throughout the Oriental and Occidental tropics, and 

 there is a strong generic similarity in their foliage. The fossil species of 

 Dalbergia are numerous, extending from the Upper Cretaceous through 

 the Tertiary.
