Order ROSACEA. 
Prunus? acurtrotia Newb. n. sp.

Locality: Woodbridge.

Leaves 2 to 5™ in length, quite unsymmetrical, narrowed to the base, 
which is sessile or short petioled, expanded and rounded above, with a 
peculiar point at the summit. 
Among the numerous smaller leaves contained in the collection there 
are a few which have the general character attributed to Dalbergia by Heer. 
These are represented on Pl. XLII, figs. 17, 18, and perhaps 19. As they
