106 WILSON EXPEDITION TO CHINA 



to interpret correctly Andersson's species. Of Wallich's type specimen of S. uro- 

 phylla the Arnold Arboretum has received a photograph and some fruits by the 

 kindness of the Keeper of the Kew Herbarium, but the material is very poor and, 

 as already said by Hooker f., " too incomplete to found a species upon." According 

 to Hooker it came " from a plant no doubt cultivated at Oude," while Dr. Stapf, 

 in a letter, says that No. 370S is "from the Kootukonnaut Forest," of which he 

 has not been able to trace the name, " but from the fact that Wallich collected 

 3708 on the 5th March and was at Rampur on the 27th February it is quite clear 

 that the locality must be in the extreme northwest of Oude." The species of sect. 

 Acmophijllae need a very careful study.
