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



house in the extensive collection of Mr Cunningham at Comely Bank 

 Nursery, near Edinburgh, where they were profusely covered with blos- 

 soms in April. It is extremely difficult to get written characters to dis- 

 tinguish E. cercBflora^ E. nivalis^ and E. impressa, though obviously very 

 different species. The difficulties are increased by each seeming to vary 

 considerably, and that in parts of structure which were considered dia- 

 gnostic of the species. In the reformed characters which I have attempt- 

 ed here, I am forced, in distinguishing these three from each other, to re- 

 ly chiefly on the tube of the corolla. 



There is a variety of E. nivalis cultivated by Mr Cunningham, and ob- 

 tained from Mr Low under the name of E. variabilis, in which the buds 

 are suberect, the peduncle as long as the calyx, the tube of the corolla 

 three times longer than this, twice as long as the leaves, and the sides 

 grooved nearly along their whole length, the throat being slightly con- 

 tracted ; in all of which there is a departure from what has been consi- 

 dered the type of E. nivalis, and the flowers are larger than in this, the 

 plant is more robust, slightly different in habit, and is rather less easily 

 propagated by cuttings. 



Epacris cercejlora is a much smaller plant than either of the others, the 

 wood is much more slender, the leaves more crowded, and the flowers 

 little more than half the size of theirs. 



Epacris impressa, — Foliis lanceolatis, patentissimis, nudiusculis, infra ner- 

 vosis, apice attenuatis, mucronatis, marginibus scabris, petiolis brevis- 

 simis ; floribus pendulis, axillaribus, solitariis, in pseudo-spicis congestis, 

 corollse tubis prismaticis, calyce acuto ciliato multo longioribus. 



Epacris cer^flora, — Foliis lanceolatis, patentissimis, nudiusculis, sub- 

 aveniis, apice attenuato-mucronatis, marginibus scabris ; floribus patulis, 

 axillaribus, solitariis, secundis ; corollse tubo ovato, calycem acutum ci- 

 liatura bis superanti. 



Eucalyptus amygdalina. 



E. amygdalina; operculo hemisphaerico, submutico, cupula, breviore; pe- 

 dunculis axillaribus et lateralibus, teretiusculis, petioli longitudine; 

 umbellis 6-8-floris, subcapitatis ; foliis lineari-lanceolatis, basi attenu- 

 atis, apice acuminato-mucronatis — Decand.

 Description. — With us a rather slender-wooded shrub. Branches pendu- 

 lous. Leaves (3-4 inches long) petiolate, linear-lanceolate, acuminato- 

 mucronate, sometimes falcate or subsessile, ovato-elliptical and mucro- 

 nate ; glaucous, especially when young ; distantly sprinkled with minute 

 transparent dots ; middle rib strong, veins and marginal callosity scarcely 

 visible till dry. Flowers in axillary 5-8 (or more) flowered corymbs ; pe- 

 duncles scarcely longer than the petiole, stouter than it, nearly round, or 

 obscurely furrowed ; pedicels resembling the peduncle, and not much 

 more slender. Calyx, including the cohering segments of its limb (oper- 

 culum) scarcely so long as the pedicel; operculum hemispherical, mi- 

 nutely pointed, shorter than the tube (cupula). Stamens numerous, 

 white, longer than the cupula. Style longer than the cupula, but shorter 

 than the stamens. 

 This species, native of Van Diemen's Land, flowered at the Botanic Gar- 

 den in the beginning of this month, when trained against the wall. We 

 have not yet ascertained whether, like the Eucalyptus pulverulenta, it will 

 thrive without this protection. 



The descriptions of Fritillaria minor, Leontice Altaica, Libertia crassa and 

 formosa, the new species Syringa Jacquinii, Oxylobium ellipticum, and Pri- 

 mula amcena, from want of room are delayed until our next publication.
