PLATE CCXCII. GERANIUM UNDULATUM. _Waved-flowered Geranium._ CLASS XVI. ORDER IV. _MONADELPHIA DECANDRIA._ Threads united. Ten Chives. ESSENTIAL GENERIC CHARACTER. MONOGYNA. Stigmata quinque. Fructus rostratus, penta-coccus. ONE POINTAL. Five Summits. Fruit furnished with long awns, five dry berries. SPECIFIC CHARACTER. Geranium foliis lanceolatis ciliatis, sub-integris; petalis sub-æqualibus, sub-linearibus, undulatis; floribus umbellatis, pentandris; radice tuberosa. Geranium with lance-shaped flowers, fringed nearly intire; petals almost equal, nearly linear, waved; flowers grow in umbels, five fertile chives; root tuberous. REFERENCE TO THE PLATE. 1. The Empalement cut open, to shew its tubular structure. 2. The Chives and Pointal, natural size. 3. The Chives, magnified and cut open. 4. The Pointal and Seed bud, magnified. This tuberous rooted Geranium, from the Cape of Good Hope, has some affinity with the G. spathulatum, as to the shape of the leaves; but the whole habit of the plant is so totally different, that we could not, with any degree of propriety, consider it as a variety of that species. Our figure was taken from a plant in the Hibbertian collection, to which it was introduced in the year 1800, by Mr. Niven. It flowers in June, and may be propagated by the root. The treatment is the same as that required for the rest, of this division, of the Genus. [Illustration] PLATE CCXCIII. LACHNÆA PURPUREA. _Purple-flowered Lachnæa._ CLASS VIII.
