Thirteen genera, comprising about 200 species, are referred to this order. With few exceptions, they are shrubs or small trees, inhabiting the northern hemisphere.

VALERIANEZ. 67

Order LXXII. VALERIANE. Valerianee, Benth. et Hook. Gen. Plant. 11. p. 151.

Annual or perennial herbs, or rarely shrubby. There are nine genera, embracing about 300 species, the greater part of which inhabit the temperate and cold regions of the northern hemisphere and the Andes of South America. A few occur in Brazil, Guiana, and the West Indies; only one, and that probably introduced, in South Africa ; in Tropical Asia they are exceedingly rare; and none are known from Australasia.

Order LXXIII. COMPOSIT.

Composite, Benth. et Hook. Gen. Plant. ii. p- 163.

Shrubs or herbs, rarely trees. Bentham and Hooker estimate the number of species at 9800, which they refer to 766 genera; whilst some authors would raise the number of genera to 1000, and the number of species to 12,000.

Tribe I. VERNONIACEZ. Vernoniacee, Benth. et Hook. Gen. Plant. ii. pp. 165 et 169.

This tribe consists of forty genera, and is remarkable alike for the number of mono- typic genera and for the large number of species belonging to the genus Vernonia itself. It is essentially a tropical and subtropical tribe, having its greatest concentra- tion of species in South America. Few of the species are peculiar to Australia; and the tribe is unrepresented in Europe.

We find no mention of this plant in Seemann’s Botany of the Voyage of the ‘Herald’; but there is ample material of it in Kew herbarium. It differs from P. trinervia and P. pilosa in its flower-heads containing only three flowers in an involucre of three bracts, and in the latter being hairy on the back, as well as in other

details. From P. serrata it differs in its hairiness, foliage, and achenes.

It was not until after the plate had been printed off that we discovered Schultz had already described this plant under the name of Ageratum microphyllum. We had overlooked this in consequence of a memorandum in Kew herbarium to the effect that the plant was not mentioned in the Botany of the ‘Herald.” By a slip in the

‘Genera Plantarum,’ the pappus is described as consisting of ten instead of five pales.
