ITi Dr Graham's Description of New or Rare Plants. 



low, granular, stipitate, arising from small brown glands, pollen granules 

 course, angular, elongated. Stigma small, round, gi-een, placed on the 

 inside of the column, and connected to the glands from which the pollen 

 masses arise by the upjiermost of two parallel green ribs, which pass for- 

 ward to the edges of the column. Germen green, curved, furrowed, 

 scarcely twisted, about as long as the lip, and rather shorter than the 

 spur. 

 The specimen described flowered in a cold frame in the collection of P. 

 Neill, Esq. of Canonmills, in May List. The flowers have been expanded 

 about six weeks, and will not immediately {a.<ie. It was received by Mr 

 Goldie from the neighbourhood of Montreal in autumn 1829, and com- 

 municated by him to Mr Neill in March last, under the name of Ilahe- 

 naria obtusata ? the specific name being given with some hesitation ; and 

 I have the same plant, under the same name, with the same uncer- 

 tainty, from mr liberal friend Dr Boott, gathered in woods on the 

 AVhi'te Mountains, North America. I have some doubts as to its being 

 the species mentioned by Pursh, but having no means of certainly de- 

 termining this, I do not feel nn-self at liberty to act with more decision 

 than Dr Boott and Mr Goldie, the last of whom, if not both, I believe, 

 examined the plant in its native stations. My doubts arise from the 

 form of the leaf, the number of the flowers, r.nd the compaxative length 

 of the segments of the perianth, to none of which the expressions of 

 Pursh apply. On the specimen of Dr Boott, however, there are but 7 

 flowers, and the leaf is more attenuated at the base, than in Mr Neill's 

 plant. 



Halenit; Fischerii. 



H. Fischerii ; corolla 4-partita, calcaribus rectis, pratulis ; laciniis calycinis 

 subulatis ; caule ramoso-erecto ; foliis subsessilibus, trinervibus, inte- 

 rioribus obovatis, superioribus ovato-lanceolatis, carinatis; |iedunculis 

 solitariis, termiualibus. 



DiscRiPiTOX Root annual. Stem (3 inches high>erect, enlarging upwards, 



purple below, green above, with 4 sides of unequal breadth, which alter- 

 nate at the joints. Leaves opposite, decussating, and at the top of the 

 stem, four in a verticel, from approximation, and therefore imbricated at 

 their base, subpetioled, decurrent, S-nerved, glabrous on both sides, the 

 lower obovate, blunt and nearly flat, the upper (|th of an inch long, Jth 

 of an inch broad) ovato-lanceolate, acute, keeled. Ferbindcs (4^ lines long) 

 solitary, one rising from the apex of a minute branch in the axil of each 

 leaf, and one terminating the stem, therefore five at the top, always sin- 

 gle-flowered, shorter than the leaves. Calpx 4-parted, segments awl- 

 shaped, imbricated, sparingly provided with minute glandular pubescence 

 (every other part of the plant being glabrous), spreading, shorter than the 

 peduncles along which they are decurrent. Corolla yellow or brownish- 

 yellow, ovate, equal in length to the peduncle, 4-cleft, 4-spurred; segments 

 broadly ovate, acute, always connivent, at least I have never observed 

 them to expand in any weather, or at any hour of the day ; spurs rather 

 shorter than the calyx, straight, spreading, conical, compressed laterally. 

 Stamens 4, arising from the corolla at the base of the fissures, and there- 

 fore alternating wfth the segments, occasionally an abortive fifth stamen 

 rises from below the middle of one of the segments at the mouth of the 

 spur ; filaments awl-shaped, shorter than the spurs, approximaticg at 

 their bases, the upper part being erect ; anthers 24obed, bursting early 

 alontr their fronts. Germen elliptical, subtetragonous, unilocular, bival- 

 vular, and empty at ' he apex. Stigmata 2, diverging, sessile. Ovules 

 large, round, attached to the sides of linear, parietal receptacles. 

 The plant was raised from seed transmitted through Mr Hunneman in 

 March 1829 to the Botanic Garden by Dr Fisher, as a species of Ha- 

 lenia gathered in Dahurica. It flowered very freely in the open border 

 in June, and probably will ripen its seeds.
