268 VALERIANACEAE

The more numerous pairs of leaflets 8 10 (in sambucifolia 4-6), the more 

 spreading leaves, and divaricate cyme distinguish it from the next species. 



Dr. Lange, Mr. Daydon Jackson, Sir J. D. Hooker, &c., have been followed 

 in retaining the name V. officinalis for this species. V. Mikanii is untenable 

 (if for no other reason) on account of the earlier V. Mikaniae, Lindley — 

 a Gruatemalan plant — the spelling of w^hich only differs by a single letter, 



F. officinalis has been seen by me at Loudwater in Bucks, near 

 Idstone in Wilts, and in Oxfordshire ; and it is recorded for Hants 

 and Surrey.
