in the lake at Mantua, to ^vliicli Mr. Ray hath put dowu that he 

 never saw it before ; nor have I seen it growing. You Avill 

 in your nest more particularly describe the places where you 



found it. . . .

In Mr. Collinson's copy of Blackstone's 'Specimen Botanicum,' 

 which had been presented by the author, the following memo- 

 randum, without any signature, has been pasted on the fly-leaf, 

 and I believe it to be in Mr. Blackstone's handwriting, and to have 

 been sent to Mr. Collinson some years before the work was 

 published : — " I don't find the Ntjmphcea alba minor taken notice 

 of in the Synopsis, fol. 368. . . . This rare plant I have twice 

 observed. The first was on the north road from York, going over 

 a stone bridge on the right hand, in a river, before one comes to 

 Doncaster ; it was then in flower, the beginning of August. The 

 second time I met with it was in going from Lindhurst (in New 

 Forest) to Brockenhurst. There is a watercourse at the entrance 

 of the village, over which there are bridges, but it being dry 

 weather there w^as no rmining stream, but the water stood 

 in pools. In the pools I observed both the small and great 

 Water Lilly : they were both in blossom, for the distinction was 

 easily made, and the difference is pretty remarkable. August 10, 

 1739." By an additional note, the plant at Brockenhurst appears 

 to have been again in flower on August 1, 1740. 



(Enothera biennis. — (E. rosea and (E. pumila were garden 

 floM-ers in the eighteenth century. Several of them are now im- 

 perfectly naturalized in this country. CE. pumila sprang up of its 

 own accord in a garden in Chelsea, in the summer of 1861. 



Ophrys apifera. — Curtis, in Fl. Londinensis, wrote — " This 

 with other Orchids was cultivated with great success by the late 

 Peter Collinson, Esq. (whose memory will always be revered by 

 every botanist), in his garden at Mill Hill. His method was to 

 place them in a soil and situation as natural to them as possible, 

 and to suffer the grass and herbage to grow around them.'^ 



Ophrys muscifera. — Orchis Myodes major. "Mem. July 

 4, 1757.— Went to the Duke of Portland's, at Bulstrode; 

 stayed to the 11th. In returning found the great Fly Orchis 

 on the declivity of a chalk pit, in full flower, in Esquire Cook's
