ERICE^. [Andromeda. 



Imearia, integerrima, obtusa, patentissima, plus minus reflcxa, supra plana, subtus dorso obtuse canaliculate. 

 Pedunculus subsolitarius, terminalis, brevis, curvatus, uniflorus. Flos nutaus. Caii/x pentapbyllus, foliolis 

 ovalibus obtusis valde concavis. Corolla lato-carapanulata, profunde 5-partita, fere 5-petala. Filamenta 

 subulata. Antlierm didyrase, dorso aristis duabus longissimis deflexis. Ovarium globosum, rugosum. Stylus 

 basi insigniter iacrassatus* 



Hab. North-West Coast of America, probably on Banks' Islands. Mr. Menzies (in Herb. nostrS) — 1 am 

 indebted for a small but original Pallasian specimen of this beautiful plant to Dr. Fischer, with which this 



exactly corresponds.

3, A. lycopodioides ; caule filiformi diffuse vage ramoso, foliis quadrifariis arete imbricatis 

 appressis ovatis brevibus crassis obtuse carinatis, pedunculis subgeminis axillaribusj corollis 

 campanulatis. — Pali, FL Ross, v. 2, p. 55, t. 73. y^ 1. Cham, in Linncea, v, \, p. 516. 



Hab. Unalaschka. Chamisso. — At first sight this plant resembles a small state of A. tetragonal but it is 

 truly distinct; much slenderer in all its parts, the branches more diffuse and flexuose, the leaves not furrowed 

 on the back, the flowers fewer but larger, and the corolla more campanulate. 



4. A, cupressina; caule suberecto valde subpiniiatim ramoso, foliis quadrifariis arete Im- 

 bricatis appressis lato-lanceolatis carinatis, pedunculis solitariis lateralibus. 



Hab. Rocky Mountains north of the Smoking River, lat. 46^. Drumrnond. — This partakes of some of the 

 characters of the preceding and following species, yet is quite distinct from both; it has nearly the same firm 

 and stout habit as A. tetragona, and is about of the same size; but, like A, lycopodioides ^ it wants the dor- 

 sal sulcus. Its leaves are longer and narrower than either, and distinctly, and often rather sharply carinated. 

 It is probably a rare, and exclusively an alpine species; very few specimens are in the Collection, and 

 those mostly in fruit. Capsule bearing the dissepiment in the middle of the valves, as is probably the case with 

 all the quadrifariously-leaved species, hence they are true Andromedts, not Menziesia, whither Dr. Fischer 

 is disposed to refer them. The beautiful A. ericoides, which 1 have received from Dr. Fischer and Chamisso, 

 and A. Hedowskii, which 1 possess from Professor Lehmann, seem to be exclusively Siberian plants, and 

 not to have been found on the opposite or American side of Behring's Straits. 



5, A. tetragona; caule suberecto fere pinnatim ramoso, foliis quadrifariis arete imbricatis 

 appressis ovato-lanceolatis subtrlquetris sulco dorsali, pedunculis solitariis axillaribus spar- 

 sis, corollis ovato-campanulatis. — Linn. — Pursh^ FL Am. v. \. p. 290. Hook. BoL Mag.

Hab. From lat. 54° to the Arctic Islands {Dr. Richardson, Captain Sir E. Parry, ^c.) and from Labra- 

 dor on the east {Koklmeister, Dr. Morrison}, to the Rocky Mountains, both on the east and on the west 

 side (Douglas). Unalaschka. Chamisso. — Its southern limit is perhaps lat. 44°, where Mr. Douglas 

 finds it on Mount Hood of the Columbia River.

Hab. From Lake Huron {Dr. Todd) to the Arctic sea-shore. Dr. Richardson. Newfoundland. Dr. 

 Morrison. Labrador. Pursh. Kohlmeister. — The more northern specimens are smaller, and have much 

 narrower leaves.
