Botanical Description.--A small tree 11 or more feet high, branches opposite, quadrate at the extremities. Leaves opposite, oval, oblong, smooth, entire, glabrous. Petioles very short, with 2 broad, lanceolate stipules curved outward. Flowers white, opposite the leaves, fixed on globose, solitary receptacles from which spring the flowerets. Calyx proper, very short, monophyllous, a lanceolate leaflet springing from the border. Corolla tubular, woolly inside about the middle, with 5 lobules. Stamens 5, inserted on the walls of the corolla. Anthers thin, incumbent. Pistil somewhat longer than the corolla. Stigma cleft in 2 laminæ. Fruit: the receptacle of the flowerets ripens to a globe bristling with the remains of the calyces, like a berry covered with many smaller ones, each containing 2 monospermous, quadrangular seeds. _M. tinctoria_, Roxb., is a climbing shrub with leaves opposite, ovate, keeled; petioles very short; flower and fruit like the foregoing species. Habitat.--In Luzon and, especially the M. tinctoria, in Malinta, Calauan and Tanauan. _Pæderia foetida_, L. (_P. sessiflora_, DC.) Nom. Vulg.--_Kantutan_, _Kantutæ_, Tag.; _Lilitan_, _Tæ-tæ_, Vis. Uses.--The foetid odor of this plant has suggested both the technical and common names for it. The natives regard it as a cure for rheumatism. The root is emetic. The leaves, boiled and mashed, are applied to the abdomen in retention of urine; the decoction of the leaves is used for the same purpose and also has some reputation as a solvent for vesical calculus. For fever, cloths soaked in the decoction are applied to the head, the same preparation being given internally at the same time. Botanical Description.--A slender, twining plant with leaves 3' by 1', opposite, oval, acute, entire, long petioles and caducous stipules.

Ovary inferior, flattened, 2 uniovulate locules. Style with 2 stigma-bearing branches. Habitat.--Luzon, Mindanao, Cebu, Panay. COMPOSITÆ. _Eupatorium Ayapana_, Vent. Nom. Vulg.--_Aya-pana_, Sp.; _Ayapana_, _Apana_, Tag.; _Ayapan_, Indo-Eng. Uses.--A native plant of Brazil now naturalized and well known in the Philippines and many other tropical countries; it is called by its Brazilian name, Aya-pana, more or less modified. The entire plant is aromatic and its infusion has an agreeable, bitter taste. Its virtues have been much exaggerated, but it is certainly a good stimulant, diaphoretic and tonic. An infusion, 30 grams of the leaves to 1 liter of water, is given in dyspepsia, a small cup after each meal. In the island of Mauritius this infusion was widely used as a stimulant and aromatic in the cholera epidemics of 1854 and 1856.
