208 BOTANY OF SOCOTRA. 



specimens in Kew Herbarium from Abyssinia. It is questionable whether 

 this is a true species. It has general resemblances with several of the south 

 European forms, 0. minor and its neighbours ; and whilst its distinguishing 

 feature is the low insertion of the stamens upon the corolla tube, this is a 

 sexual character of really no specific value.
