Dr Graham's List of Rare Plants. 



Description. — Roots fleshy, cylin- 

 drical. Btdb ovate, much com- 

 pressed, green, with two indistinct 

 rounded angles on each side. Leaves 

 numerous, equitant, lanceolate, acu- 

 minate, bright green and shining, 

 rising from the base of the old bulb, 

 and before any distinct bulb is 

 formed at their origin. Scapes se- 

 veral from the base of the bulb, 

 slender, round, jointed, having a 

 marcescent brown sheath at each 

 joint. Flowers solitary. Perianth^ 

 3 outer segments spreading, green- 

 ish-yellow, acuminate, puljescent 

 on the inside near the base, espe- 

 cially the upper one, which is lan- 

 ceolate, the others ovate, dilated 

 downwards, covering laterally the 

 rounded base of the Tip, but scarce- 

 ly involute, and here quite uncon- 

 nected with each other; 2 inner 

 segments lanceolate, pointed, re- 

 flected at the apex, entire. Lip 

 semicylindrical, fleshy (as is the 

 whole perianth, though in a smaller 

 degree), pubescent within, parallel 

 with the column, and loosely arti- 

 culated with its elongated base ; la- 

 teral lobes small, their upper edges 

 somewhat involute, their apices 

 turned a little down ; middle lobe 

 nearly as long as the inner seg- 

 ments of the perianth, reflexed, 

 rounded at its apex, and edged with 

 minute teeth, attenuated at the 

 base, inserted into the back of a 

 broader internal lobe, which is 

 quite entire, reflected at the mar- 

 gin, and ascends in a point at 

 each side, so as nearly to touch 

 the lateral lobes towards their ex- 

 tremities ; labellum and inner seg- 

 ments of perianth orange-yellow, 

 sprinkled on the inside with red 

 dots. Column linear, pubescent in 

 front, especially towards the top, 

 beaked above the stigma. Anther 

 terminal ; pollen-masses 2, yellow, 

 rounded, scarcely flattened, each 

 furrowed in the outer side, attach- 

 ed by very short partial pedicels 

 to the summit of a flat white com- 

 mon pedicel, which is rather longer 

 than the pollen-masses, and is re- 

 flected under the anther-case from 

 the beak of the column, to which 

 it is attached by a round flat scale ; 

 anther-case blunt. Germen 6.fur- 

 rowed. 



The flowers are perfumed very like 

 to Cinnamon, from which circum- 

 stance I have taken the trivial 

 name. 



This very pretty parasite is a native 

 of Mexico, where the bulbs were 



f)rocured by Lord Napier, and ob- 

 igingly communicated to the Royal 

 Botanic Garden at Edinburgh in 

 1825. 



Medeola virginica. 

 Has flowered very freely and in large 

 quantity in a cold frame. 



Phlox nivalis. 



Pogonia ophioglossoides. 



This plant having been presented in 

 large quantity by the Countess of 

 Dalhousie, forms a turf, and flowers 

 most freely in a cold frame. 



Pyrola umbellata. 



Protea melaleuca. 



Puschkinia scilloides. 



Pyrethrum diver sifolium. 



Stem herbaceous, pale green, and co- 

 vered with lax hairs which decrease 

 upwards, leading shoot erect, many 

 others arising in a circle from its 

 base, diverging, branching, and ex- 

 ceeding the leading shoot in height. 

 Leaves linear, ciliated, but other- 

 wise less pubescent than the stem, 

 pinnatifid in more than the upper 

 half, pinnae incised ; nearly the 

 lower half entire, ovate, semi-am- 

 plexicaul; pinnatifid portion gra- 

 dually diminishes upwards, and is 

 entirely awanting in several of the 

 uppermost leaves, which are quite 

 entire, ovate and acuminate. Flow- 

 ers terminal. Calyx semi-globular, 

 imbricated in two rows, the scales 

 of equal length, at their edges, and 

 especially at their rounded extre- 

 mities, membranaceous, transpa- 

 rent, colourless (though reddish in 

 the bud), every where else, like 

 every part of the plant, except the 

 flower, pale green; membranous 

 terminations spread upon the back 

 of the ray. Florets of the Ray spread- 

 ing, at length revolute, entire at 

 the apex, pointed, white, tinged 

 with red along the centre of the 

 outside while m bud. Disk round- 

 ed, yellow, florets funnel-shaped, 

 tube nearly half as Iwig as the limb ;
