| Abstract | The morphology and nodal anatomy of Hornstedtia conoidea Ridl., a wild Philippine endemic ginger, are herein described based on ocular and microtechnique observations. Hornstedtia conoidea is an erect plant reaching 3 meters tall; rhizome 28–35 cm long, 2–2.5 cm thick; leaves distichous, lanceolate, 55–63 cm and 11–13 cm; inflorescence spindle-shaped, 10–13 cm long 3–4 cm wide, covered with involucral bracts; infructescence enclosed by the enlarged bracts, dehiscent, with fruits measuring 12.5–14 cm long by 4–5 cm wide. Nodal anatomy of rhizome (young, middle-aged, old) showed the presence of collateral vascular bundles, endarch xylem differentiation, atactostele, unilacunar-multitraces nodes consisting of one leaf gap, multi leaf traces and having a single-layer of epidermis; also present is an endodermoidal layer consisting of cambium-like cells, the latter is a diagnostic character of Zingiberaceae. |
