later by the Spaniards); siempre viva (Bryophyllum pinnatum Kurz), for medical purposes; horse radish tree (Moringa oleifera Lam.), for food and medicine; sappan (Caesalpinia sappan L.), for dyeing; the tamarind (Tamarindus indica L.), for food; indigo (Indigofera tinctoria L.), for dye; "caturay" (Sesbania grandiflora Pers.), for its edible flowers and its resinous exudation; the pigeon pea (Cajanus cajan Merr.), for food; the cow pea (Vigna sesquipedalis L.), for food; the asparagus pea (psophocarpus tetragonolobus DC.), for food; "batao" (Dolichos lablab L.), for food; the mungo (Phaseolus radiatus L.), for food; various citrus fruits, such as the pomelo (Citrus decumana Murr.), the lime (C. lima Lunan.), and varieties of the orange (C. aurantium L.), for food; the santol (Sandoricum koetjape Merr.), for food; the lansone (Lansium domesticum Jack), for food; some euphorbias (E. tirucalli L.), for medicine; "iba" (Cicca disticha L.), for food; crotons (Codiaeum variegatum Blume), for ornamental purposes; castor oil plant (Ricinus communis L.), for medicine; croton oil plant (Croton tiglium L.), for medicine and for poisoning fish; balsam (Impatiens balsamina L.), for medicine and for ornamental purposes; cotton (Gossypium sp.), for textile purposes; silk cotton tree (Ceiba pentandra Gaertn.) for its fibrous floss; various Eugenias (E. jambolana Lam., E. malaccensis L., E. jambos L., and E. javanica L.), for food; "papua" (Nothopanax fruticosum Miq.), for medicine and for ornamental purposes; jasmine (Sasminum sambac Ait.), for its fragrant flowers; "solasi" (Ocimum basilicum L., and O. sanctum L.), for condiments; sesame (Sesamum orientale L.) for its oily seed; the bottle gourd (Lagenaria leucantha Rusby), for food; the sponge gourd (Luffa cylindrica Roem. and L. acutangula Roxb.), for food; the "condol" (Benincasa hispida Cogn.), for food; and the "ampalaya" (Momordica charantia L.) for food. From an examination of the above list it will readily be seen that a great number of species were purposely introduced in prehistoric times from various parts of the East, chiefly through Malaya, for one reason or another, usually for their food value or for other reasons of economic importance. It is quite certain that none of the species enumerated above are natives of the Philippines, and it is equally certain that none reached the Archipelago without the aid of man. Again it is equally certain that, with possibly very few exceptions, all these species were introduced by the early Malay invaders, by their successors, or by peoples of various other nationalities with whom they came in contact, long before the advent of the Europeans in the Orient."--"Notes on the Flora of Manila with special reference to the Introduced Element.
