TENDRIL: A spirally, coiling, thread-like organ that attaches itself to another body for support, as in the Grapevine or Virginia Creeper. A tendril may be a modified stem, branch, leaf, or stipule.
TENSION: A term related to soil moisture and the equivalent negative pressure of suction of water in the soil.
TEPAL: In some flowers, such as the Tulip and Begonia, the calyx and corolla aren't clearly differentiated; the proper name for one of these petal-like parts is tepal.
TEPEE: This is a cone-shaped structure consisting of three or more stakes bound together near the peak used to grow vine crops such as peas, beans, and cucumbers.
TERETE: Pencil-like; round in cross-section; cylindrical, but usually tapering at both ends, such as a terete seedpod.
TERMINAL: Growing at the tip of a branch or stem, often applied to a bud, rosette, or flower.
TERNATE: Arranged in three's; especially said of a leaf with three leaflets, or of leaves whorled in three's. If the three divisions of a ternate leaf are subdivided into three leaflets each, the leaf is biternate, and yet another subdivision is called a triternate leaf.
TERNATISECT: Cut into three lobes or partial divisions.
TERRACE: 1. A ridge made across sloping soil on the contour or at a slight angle to the contour that intercepts and delays surplus water for absorption into the soil. All excess water may be forced to flow slowly into prepared outlets. 2. A raised level faced with masonry or turf; an elevated flat space, such as a garden terrace; also, a natural formation of the ground resembling such a terrace.
TERRACOTTA: A brownish-orange earthenware used to make pots.
TERRARIUM: An enclosed environment for plants or land animals; a place where such plants or animals are kept alive for study or observation.

TESSELLATION: A checkered pattern.
TESTA: The hard outer coating of a seed; episperm.
