Rhomboid, diamond-shape, approaching to a square. 



Ringent, or labiate corol ; one which is irregular, monopeta- 

 Icus, with the border usually divided into two parts, 

 called the upper, and lower lip; gaping like the mouth 

 of an animal.

 flowers and fruit, but no leaves. As in Narcissus, 

 Dandelion, and Hyacinth. 



Scarious, tough, thin, and semi-transparent, dry, and sonorous 

 to the touch; as a perianth. 



Serrated, Serratures, like the teeth of a saw, and pointing 

 towards the extremi.y of the leaf, as in the nettle and 

 rose. Some leaves are doubly serrated, having the 

 teeth again cut into other little teeth, as in canterbury 

 bell. 



Sessile, or sitting, when a leaf grows immediately to the 

 stem, or stalk, branch, or root, without any foot-stalk. 

 A Sessile flower, has no peduncle, or flower-stalk. 



Sheath, a tubular or folded leafy portion inclosing the stem; 

 as the leaves of grasses. 



Silique, (Siliqua, L.) a pod or seed-vessel usually longer 

 than it is broad, with two valves or covers, and sepa- 

 rated by a linear receptacle, the seeds alternately fixed 

 to both sutures, or seams, as in the common stock. 



Simple leaves, are such as have only a single leaf on the 

 petiole or foot-stalk; not divided, branched or com- 

 pounded. 



Simple, not divided, branched, or compounded. 



Sinuate, having sinuses at the edge. 



Sinus, a large rounded indentation or cavity. 



Spadix, an elongated receptacle of flowers, commonly pro- 

 ceeding from a spathe. 



Spathe, a sheathing calyx opening lengthwise on one side, 

 and consisting of one or more valves; as in the onion. 

 See Spadix. 



Spike, a species of inflorescence, in which sessile flowers 

 are alternate, on a common simple peduncle, as in 

 Wheat, Rye, Lavender, etc. An ear of corn, or grain, 

 is called a spike; it is particularly applicable to ears 

 of maize. 



Spur, a sharp hollow projection from a flower, commonly the 

 nectary. 



Standard, the upper petal, or banner, of a papilionaceous 

 corol. 



Stipule, a scale or small leaf situated on each side, and some- 

 times on one side only, of the base of the leaf-stalks, 

 for the purpose of supporting them at their first ap- 

 pearance, as in vetches. Sometimes it is united lat- 

 terly to the foot-stalk, as in the rose. 



Striated, marked with fine hollow parallel lines. 



Strobiles, or Cone, a kind of seed-vessel, formed by a catkin, 

 with hardened scales, and containing a seed withiu the 

 base of each scale, as in the fir. 



Subsessile, almost sessile; having very short foot-stalks. 



Subulate, awl-shaped; linear, or slender at the base, and gra- 

 dually tapering towards the end, like an awl. 



Sutures, or seams, the edges by which the valves are con- 

 nected, which is the external covering of the seed. 



Sword-shaped, or Ensiform, two edged, tapering to a point, 

 and somewhat convex on both surfaces, as in Iris. 



Tendril, a filiform appendage of certain vines, which sup- 

 ports them by turning round other objects. 



Terminal, when it terminates a stem, or branch. 



Ternate, growing by threes, as in Trefoils. 



Thread-shaped, see filiform. 



Tomentous, downy, nappy, cottony; covered with hairs so 

 close as to be scarcely discernible. 



Trifid, divided into three parts; by linear sinuses, with 

 straight margins; three-cleft. 



Truncate, having a square termination as if cut off; as the 

 leaves of the Tiriodendron Tulipifera. 



Tuberous, from tuber, a bunch. Consisting of roundish 

 fleshy bodies, or tubers, connected into a bunch by in- 

 tervening threads; as the roots of potatoes, artichokes, 

 etc. 



Umbel, a kind of inflorescence in which the flower-stalks di- 

 verge from one centre like rays; as in the Parsnip, 

 Parsley, etc. See Cyme. 



Undulate, when the middle part of the leaf, especially as it 

 approaches the margin, is acutely folded up and down, 

 as in the Mallows . 



Valve, the outer coat, shell or covering of a capsule or other 

 pericarp, or rather one of the pieces which compose 

 it; also, one of the leaflets composing the calyx and 

 corol in grasses. 



Veiny, when the fibres on the surface of the leaf are branched, 

 as in the hawthorn. 



Ventricose, swelling out in the middle; as a ventricous pe~ 

 rianth. 



Verticillate, whorled. Having leaves given off in a circle 

 round the stem. 



Villous, having the hairs long and soft. 



Vivaparous, producing a collateral offspring by means of 

 bulbs. 



Whorl, or Verticillate, in which the flowers surround the 

 stem in a sort of ring, though they may not perhaps be 

 inserted on all sides of it, but merely on two opposite 

 sides, and even on one side only. 



Wings, the two lateral petals of a papilionaceous flower. 



Winged, having the sides extended into a leafy expansion.
