XIX. Observations on some Species of Menziesia, hitherto consi- 
dered as belonging to the Genus Andromeda, by Ol. Swaktz, M.D. 
Bergian Professor of Botany at Stockholm, F.M.L.S. 
Read April 17, 1810. 
Tue great natural affinity between the genera of Erica, Andro- 
meda, and Menziesia is well known; but at the same time it ap- 
pears unquestionable that they can never unite with each other. 
The character of the Menziesia was first explained by the Pre- 
sident of the Linnean Society, i in his excellent work the Plante 
hactenus inedita, t. 56, where he points out the principal generic 
difference from the real Andromedas and Ericas to be, a capsule 
similar to that of Rhododendron, or the dissepimenta loculorum 
e marginibus valoularum inflexis, which accordingly places. this 
genus in a natural order distinct from the Ericee. The author 
of the Gen. Plant. secundum Ord. Nat. disposita, attending to the 
character of Menziesia, indicated afterwards (Annales du Mus. 
d' Hist. Nat. i. p..52.) the necessity of transferring another plant 
to the same genus, viz. the Erica or Andromeda Daboecii of dif- 
ferent authors, who, from principles not before fixed concerning 
the natural affinity, had appeared irresolute about its real place, 
now sufficiently ascertained by Mr. Salisbury (Transact. of Linn. 
Soc. vi. p. 323. B) and from my own inspection of Irish and Spanish 
specimens, | |... -* i | rated qs
