3T6 Dr Grahapi's Description of New or Rare Plants. 



cccspitosa, having gathered it on Ben- A von, and requests me "to 

 sav, that the first specimen was picked by John Mackenzie, gar- 

 dener at Invercauld, who accompanied him as guide. The 

 plant grew on the west side of Slock More, chiefly among moss, 

 on disjointed portions of rock, in a sheltered spot, about half- 

 way up the cliff. Mr Barry likewise found Alopecurus alpinus 

 in endless profusion, by a stream, which, from his description, I 

 think must lead from the hill to the south-west of the White 

 Water into Glen Prosen.

 Alstrcemeria Neillii, Gillies MS. 

 DE.scniPTioN — Stem simple, many from the same root, erect, flaccid, 

 round, very leafy, subglauco-pruinose, especially towards the top, more 

 green below. Leaves spathulate, reflected at the apex and sides, un- 

 dulato-pruinose, succulent, green, quite villous at the margin and particu- 

 larly at the apex, about 7-nerved, central rib hardly prominent behind, 

 except in the lower narrower half. Peduncles (3 or 4) forming a ter- 

 minal umbel, 2-flowered, dull purple, little longer than the leaves, which 

 are gathered in form of an involucre round their base. Perianth seg- 

 ments unequal, greatly attenuated, succulent, involute and ciliated at 

 the base, each with three primary nerves prominent behind, and 2 or 4 

 secondary nerves, scarcely reticulated ; three outer segments equal, of 

 nearly imiform pale rose colour, rather darker in the middle of the out- 

 side, obovate, crenate, with a central green concave callous point ; three 

 inner segments rather longer than tlie outer, spathulate, witli a green 

 « callous apex, and oblong deep rose-coloured spots in the upper half; the 

 lowest is rather the shortest of the three, nearly flat, and arched back- 

 wards ; the two others project in the centre of the flower, nectariferous 

 at the base, straiglit, except near the apex, where they are bent back- 

 wards, and immediately^ below this point they are marked by a broad 

 yellow transverse band. Stamens laid along the lower petal till the 

 pollen is ripe, when they become straight, nearly parallel to and ahnost 

 of equal length with the two central petals ; filaments rose-coloured, 

 slightly tapering, pubescent at the base ; anthers greenish rose-coloured, 

 flattened, and, as in the other species, when the loculaments burst, be- 

 coming flattened in the ojjposite direction ; pollen reddish, granules very 

 small and oblong. Stigma trifid, rose-coloured as well as the prismatic
