ON THE APOCINEiE. 239

Squama 5, hypogynae, conuatse.

Capsula cylindracea, bilocularis, valvis folliculiformibus, dissepimento parallelo libero utrinque seminifero.

Habitus. Frutex volubilis. Folia opposita. C^w<£ termi- nates, trichotomse. Flores inter minores, limbo barbato.

Patria. Nova Ilollandia.

Obs. This genus is perhaps too nearly related to the New Holland portion of Parsonsia, from which it differs chiefly in its fruit being capsular. It is named in memory of Israel Lyons, author of " Fasciculus Plantarum circa Cantabrigiam nascentium," and from whom Sir Joseph Banks received his earliest instructions in botany.

��APOCYNUM. [Apocyni sp. Linn, et Juss. [67

Char. Corolla campanulata. Tubus denticulis 5, acutis, inclusis, laciniis limbi oppositis. Faux nuda.

Stamina inclusa. Anther a sagittatse, medio stigmati cohserentes, lobis posticis polline vacuis.

Ovaria 2. Styli subnulli. Stigma dilatatuin, apice conico.

Squama 5, hypogynse.

Folliculi graciles, distincti.

Habitus. Herbce perennes, erectas. Folia opposita, membranacea. Flores cymosi.

Patria. America Borealis, et Europa Australis.

Obs. The Linnean genus Apocynum at present contains many plants widely different from the species of which it originally consisted. Most of the spurious species I have already referred to different genera, and I here add specific characters of all the genuine species with which I am acquainted.

1. A. androscemifolium, foliis ovatis glabris, cymis termi- nalibus lateralibusque, tubo corollae calycem bis superante. Apocynum androsaemifolium, Linn.
