stroemiacese as a small separate tribe. Scapha, Ch. and Dray- tonia, A. Gr. are united with Saurauja. Thea, as modified by Seemann, is regarded as a section of Camellia rather than as generically distinct. Btaploclathra, a new genus founded on opposite-leaved species of Caraipa, and Marila, are referred to BonnetiesB as anomalous members. Visneacece, Ch. is incorpo- rated with Ternstroemiacese. Bentaphylax is appended to the same tribe.

Ixionanthes and Ochthocosmus, Mr. Bentham excludes from the order. He considers them allied to Saxifrageae. Marcgraa- viacese, Juss. are included in Ternstroemiacese proper ; — the genus Antholonia, which has been associated with this group, De Labil- lardiere's figure would indicate to be a Bassia.

Tristylium, Turcz. is reduced to Cleyera, and XowalewsJcia, published as Ternstroemiaceous by the same botanist, is a Mexi- can Clethra. Descriptions of the species of Caraipa, and of four new Ternstroemiaceee, collected by Mr. Spruce, are appended to this paper. Bentham, George. — Notes on Anonacese. Linn. Proc. v. pp. 67-72.

Eeferring especially to the American species. Mr. Bentham, with Dr. Hooker, proposes to suppress the tribe Anonece, uniting it with Xylopiece. Oxymitra, Bhceanthus and Monodora are in- cluded in the modified tribe Mitrephorece.

Guatteriece takes the name of Unonece, the American genus Guatteria belonging to the Uvariece, which are characterized by petals imbricate in aestivation. The Asiatic species which have been referred to Guatteria are reduced to Bolyalthia.

Guatteria heteropetala, Benth., allied to Bliceantlius, is sepa- rated as the type of a new genus — Heteropetalum, as is also Tlvaria brasiliensis, Veil., under the name Cymbopetalum.

New species of Trigyneia and Bocagea are described from South America and a Monodora from the Niger. The ovary of the latter genus Mr. Bentham finds to consist of numerous carpels, as indicated by its longitudinal furrows and the curva- tures or lobation of the peltate centrical stigma.

1. Involucre of Anemone. Regarded as a single amplexicaul leaf divided to the base into distinct segments.

2. Stigmas of Bapaveracece. In Bomneyece and in Hypecoum the stigmatic summits of the carpels remain distinct and alter- nate with the placentas, indicating an approach to the apocar- pous structure of Bammculacese. In the rest of the order the stigmas, or even the summit of all the carpels are more or less confluent, as may be traced in gradation from Stylopkorum through Bocconia, Sanguinaria, Chelidonium, Argemone, Meco- nopsis and other genera to Bapaver, in which the radiating stigmas answer to the stigmatic margins of the summits of the carpel- lary leaves, and are consequently over the placentas.
