Western Szech'uan: Ching-chi Hsien, Ta-pao-shan, woodlands,

This species has not previously been reported from Szech'uan. Our specimens 

 which are in ripe fruit only, appear to be identical with Franchet's plant. The unde- 

 scribed fruit of this species is cylindrical, 4-4.5 cm. long, 8-10 mm. wide, furrowed, 

 sparsely pubescent, 8-10-celled. Seeds fusiform, 3.5-5 mm. long, blackish-brown 

 with yellowish wing. Some of the pedicels on our specimens are 0.6 cm. long. 



Of the species known from Szech'uan R. lacleum is only exceeded in size by R. 

 calophytum Franchet.
