98 same inflorescence, the inferior sepal, and one of the lateral pair, had undergone no alteration; the other lateral sepal was affected as in the other flower, being united throughout with the semi-labellum. The two lateral petals remained normal and free. Within the compound lobe, resulting from the union of the lateral sepal and labellum was an entire, free, slightly trilobate, second labellum, traversed by a thick longitudinal stripe. The right side of this labellum was nearly flat, and with an undulate margin; a portion of the left side was sharply curved inwards, becoming parallel to the rest of the segment, and between it and the column. Within these was a third and yet smaller, spreading, supplementary labellum, with its back turned to the plane face of the column, and bearing slight traces of a thickened median line. The median line of the large labellum was sensibly turned towards the left, that of the small inner one, toward the right. The three labels were placed nearly in front of each other; the intermediate free one probably representing the normal labellum.

The detail of eight observations is given upon four species (Fuchsia globosa, Veronica Lindleyana, China Aster, and Phlox decussata). From M. Duchartre's experiments it results, that plants exposed to rain for various intervals up to 12 hours, having the pots containing their roots perfectly closed, acquired no increase in weight; on the contrary, in some cases, a slight decrease was manifest, due to loss by transpiration.

These grasses are regarded as types of new and distinct genera, both of which, probably, belong to Chlorideæ—Buchlöe dactyloides, Engelm. (the Buffalo-grass of the Western Prairies), and Monanthochlöe littoralis, Engelm. (from Texas and Florida).
