On the Cultivation of Rare Plants. 



Introduced at Chapel-AUerton in 1797, having been pur- 

 chased of Messrs. Grimwood and Co. who received the 

 roots from Turin. It flourished exceedingly, and is probably 

 still at Mill Hill, where I took and left it.

Introduced by the Marquis of Blandford in 1806. I saw 

 it much increased at White Knights, in May 1809, five or six 

 plants then flowering in the same pot. Both in this and the 

 preceding species, a bulb is formed annually at the end of 

 the larger fibres, as in Pterygodium Volucre.

I found this plentifully last summer in a dry pasture near 

 Chalfont, in Buckinghamshire.

These two species succeed best in chalky soil, free from all 

 manure whatever ; but they will endure more moisture than 

 I could have supposed, for I found them in a very wet part of 

 the meadow, below the terrace, at Mill Hill, where they had, 

 no doubt, been planted by Mr. Peter Collinson. Orchis 

 Conopsea affords another singular instance of this sort, which 

 I have seen growing wild on the dryest limestone, mixed 

 with Orchis Pyramidalis, and in bogs where I could hardly 

 tread, mixed with Epipactis Palustris.
