PLANT DESCRIPTION Solanum lycopersicum Linn, Tomata/Kamatis, (Native throughout the

Philippines) Solanaceae An annual herb up to 1-3meters tall. Roots are with a taproot system with

numerous lateral roots. Stems (aerial) are with SympodiaLeaves are 12-13cm long, bipinnately compound, petiolate, exstipulate, alternate in arrangement, divergent, pinnatifid, with no leaf blade apical process. Petiole, dark green, 2.5-4cm long, terete. Leaflets, mostly opposite, irregular with leaf margin, petiolate, 5.8cm long, 2.0cm wide, oblique base, acute apex, petiolate (petiolule green, terete, 1-2cm long, scandent). All leaflets, pinnate-netted, midvein and secondary veins sunken above and raised below, pubescent. Inflorescence a terminal on the stem, simple cyme or dichotomously branched cyme, divergent, alternate of flower buds (pubescence), biseriate (dichlamydeous),  whorled, semi-unguiculate). Flowers perfect, ca 15 mm long, ca 15 mm wide, alternate, divergent, pendent, actinomorphic, pedicellate. Pedicel ca 7 mm long, tube-like. Calyx aposepalous sympetalous, actinomorphic, ca 10 mm long. Calyx lobes anisomerous,ensiform, truncate, entire(with presence of trichromes), ca 10 mm long.

Corolla lobes 5 (2 posterior, 2 lateral, and 1 anterior), trullate, apices are narrowly acute, mucronate-like,truncate base, entire. Stamens 4 fertile, uniseriate, isomerous, staminodia, subsessile, didymous, antisepalous/alternipetalous, exserted, syngenesious (anthers connate).Filaments (of fertile stamens) elongated,yellow, 2.0 mm long. Anther basifixed, longitudinally and introrsely dehiscent (downwardly dehiscent), ca. 8 mm long, thecae didymous. Pollen yellow-orange. Gynoecium syncarpous. Perianth/Androecial position hypogynous. Ovary superior, light green, 1-2 mm long, circularly. Carpels 2. Locules 2. Placentation fleshy.Ovules one per carpel. Styles 1 per pistil, terminal. Stigmas 1, terminal, tip shaped.
