The Professor does not mention the precise height which he had observed these trees to attain in North-America, but it is evident that they acquire a considerable thickness, as the wood of the root as well as the body of the tree is manufactured into various utensils by the natives, and by the Indians into spoons in particular, whence it has obtained the name of the _Spoon Tree_. The leaves have been found to prove poisonous to kine, horses, and sheep, but the deer are observed to brouse on them with impunity. PETER COLLINSON, Esq. who was highly instrumental in enriching this country with the native plants of North-America, is said to have introduced this elegant species about the year 1734. With us it succeeds best when planted with a northern aspect, well sheltered, in a soil composed of loam and bog earth, in a situation moderately moist, where the air is perfectly pure. Being with difficulty propagated by suckers or layers, it is most commonly raised from American seeds. [177] KALMIA GLAUCA. GLAUCOUS KALMIA. _Specific Character and Synonyms._ KALMIA _glauca_ foliis oppositis oblongis laevigatis, subtus glaucis, margine revolutis, corymbis terminalibus, ramulis ancipitibus. _Ait. Hort.

It is of course not described by Mr. MILLER, nor is it mentioned the in the 14th edition of LINNAEUS'S _Syst. Vegetab._ by Professor MURRAY; in the _Hort. Kew._ of Mr. AITON, it is both described and figured. It flowers in April and May, is propagated in the same manner and requires the same treatment as the _latifolia_. [178] HYPERICUM CORIS.

It grows spontaneously in the South of Europe, and many parts of the Levant; HONORIUS BELLUS, in his epistle CLUSIUS (_vid. Clus. op_.) describes it as growing on the hilly parts of the island of Crete. Mr. LEE, of Hammersmith, received it about four years since from the Crimea. It is propagated by cuttings. [179]
