To William Whewell   30 April 1859

My dear Whewell,

You will find your Catmint figured in the Bot. Mag. Pl. 923 under the name of Nepeta longiflora– But like many garden flowers it bears many synonymes. I think I recollect it in the Bot. Garden as N. cœrulea– Our Labiata Authority Bentham quotes the B. M. fig. under his N. Mussini – & for synonymes gives us longiflora, salviæflora, cyanotricha, argentea, diffusa, incana, lamiifolia, teucrioides, violacea, Willdenoviana &c. So you have plenty of choice.

He makes N. caerulea a synonyme of N. latifolia.

There is a marvellous confusion among the Catmints, several of which nearly resemble each other & have been mistaken accordingly in gardens more especially. I returned home yesterday with Anne from Kew where she had been for a few days on her way from Bath.

Y ^rs Ever truly | J S Henslow
