Under the head of ' Tricocca,' Linnaeus, in i Philosophica Bo- tanica' (1751) grouped, on the ground of their close natural affinity, a number of genera for which A. L. de Jussieu, in his 1 Grenera Plantarum' (1791) proposed the name JSujihorbice, and which constitute, with the additions since made to them, the Euplwrbiacece of most recent writers.

Prof. Klotzsch, with his colleague Dr. Grarcke, proposes to break up the group into six ' natural orders,' viz. (uni- ovulate) Euphorbiacea?, Peraceas, Acalyphacese, (bi- rarely uni- ovulate), Buxacese, Phyllanthacea?, Antidesmacese.

His Order Euphorbiacese, based upon the genus JEttphorbia as commonly received, Pedilanthus and Anthostema, is to consist of 19 genera, the section Euphorbiese, EX and Grk. including 15, viz. (A. Anisophylla3 — Involucri lobimembranacei,basi callo varii- formi (glandula) instructi). Anisophyllum, Haw., Alectoroctonum, Schlecht, Tricherosterigma, Kl. and Gk., Eumecanthus, EX and
