 Nyssa, Linn. Supposed to tie from the name 

 -of a water-nymph, on account of the habitat of 

 the plants. Linn. 23, Or. 2, Nat. Or. Alan- 

 giaccce. These trees are well suited for large 

 shrubberies ; they grow in any common soil, 

 but prefer a damp situation, growing best 



when planted on an island in. a pond or river ; . 

 they may be propagated by layers or seeds.

Ober&nia, Lindley. Linn. 20, Or. 1, Nat. Or. 

 'Orchiddcece. Two species of this remarkable 

 genus have been figured in Lindley's splendid 

 work, entitled — Serturn Orchiddceum, where 

 he makes the following remarks: — "The 

 genus Oberbnia consists principally of small, 

 fleshy-leaved epiphytes, inhabiting the branches 

 of trees in the woods of India, and having the 

 most tiny of flowers. Fourteen species have 

 been described, only a part of which have 

 been at present introduced to this country. 

 The resemblance to insects and other animal 

 forms, which have been perceived in the Or- 

 chidaceous plants of Europe, and which have 

 given rise to such names as Fly Orchis, &c, 

 may be traced so plainly in the genus Obe- 

 rbnia, in every species, that it alone would 

 furnish a magazine of new ideas for the gro- 

 tesque pencil of a German admirer of the wild 

 and preternatural. If the Brahmins had been 

 botanists, one might fancy they took their 

 doctrine of metempsychosis from these produc- 

 tions. In the genera Oberbnia and Drymbda, 

 Pythagoras would have found a living evidence 

 of animals transmuted into plants." Syno-
