52 Mr. Lindley's Remarks upon the 



to mind some of the North American species of Habenaria. 

 The flowers measure, from the base of the ovarium to the apex 

 of the lower sepals, fully three inches.

This very obscure plant was originally described by the 

 younger Linnaeus from specimens communicated to him by the 

 late Mr. Thouin from Commerson' s Herbarium ; a figure of 

 it was subsequently published by Sir James Edward Smith. 

 By both these authors the native country was stated to be the 

 Straits of Magellan, an error which was soon corrected by M. 

 de Jussieu who affirms, from the examination of Commerson' s 

 original collection, that it was discovered in the neigh- 

 bourhood of Buenos Ayres. To this Professor Sprengel, upon 

 the very indifferent authority of Molina, adds Chili. But I 

 doubt whether Molina ever saw the plant; it is more probable 

 that he confounded the B. plumosa with this species.

1. Asarca speciosa. 



Serapias Gavilu. Pavon. in herb. Lamb. 

 Habitat in Chile. Pavon. (v. s. sp. in h. Lamb.) 

 Stem about a foot high, leafy. Leaves oblong, sheathing and amplexi- 

 caul at the base, becoming smaller by degi-ees till they assume the 

 habit, but not the texture, of the squamae of Chlorsea and Bipinnula. 

 Spike lax, about eight-flowered. Bractece oblong-lanceolate, shorter 

 than the ovarium. Sepals of the same figure, ovate-oblong, acumi- 

 nate, veiny, in no degree fleshy ; the two interior more obtuse and 

 shorter. 

 The only specimen of this plant which I have seen exists in 

 the Herbarium of Mr. Lambert, where it is marked in Pavon's
