 September and November 1908 (No. 3534, type); without precise 

 locality, ravine, alt. 800 m., August 1903 (Veitch Exped. No. 4313). 



This species seems not closely related to any other species of the genus. Accord-

 this group as from those of the other groups in the entire upper hp of the corolla,
