Abstract
THIS volume will be welcomed as an addition to Mr. Miers' contributions to systematic and structural botany, all of which possess the value of the labours of a careful and accurate observer, and one especially conversant practically with South American botany. We find in this volume carefully worked papers on the Calyceraceæ, a small order closely allied to Compositæ, on the carpological structure of Bignoniaceæ, on the history of the mate plant, and the different species of ilex used in the preparation of Paraguay tea, a monograph of the Tricuspidarieæ, an essay on the genus Goupia, one on the structure of Heliotropiaceæ, and a paper on the South American forms of Ehretiaceæ. But the most important article is one on the genus Ephedra, which Mr. Miers considers has been improperly placed among gymnosperms, maintaining that it has neither naked ovules nor naked seeds, and believing that it is more allied to Urticaceæ than to Cycadaceæ or Coniferæ, presenting a far higher order of structure than these latter orders. The third volume, devoted entirely to Menispermaceæ, is promised shortly.
