the same name that Miller did. The authority therefore should 
remain as heretofore “ (Miller) Ait." 
It would be interesting to know if Miller’s Hydrangea arborescens 
is represented in his herbarium and if so by a specimen of what species. 
Is it perhaps Viburnum americanum, thus proving another instance 
of the interchange of labels or of specimens? Philip Miller was too 
discriminating a botanist ever to have described in the same volume 
identical plants under two such widely diverse genera as Hydrangea 
and Viburnum.

Farwell, but differing in the conspicuously lobed primary leaves and 
the very short achenes, the achenes of well developed var. petiolata 
being larger, the outer up to 6.5 mm. long, the inner up to 8 mm. long 
and with marginal awns up to 4.7 mm. long. In its conspicuously 
lobed leaves and short achenes var. gracilipes, which is abundant on 
Cape Cod, is close to typical B. connata; but the latter plant has the
