veloping the flowers in certain 

 monocotyledons. 



Spathulate^ more or less rounded 

 towards the summit and narrowed 

 towards the base. 



Spike, an inflorescence similar to the 

 raceme, only that the flowers have 

 no pedicels ; also, those forms in 

 which spikelets are arranged in 

 close and alternating series upon a 

 common rachis, as in some grasses. 



Spihelet, a small spike, of which 

 several, aggregated round a com- 

 mon axis, constitute a compound 

 spike ; more especially applied to 

 the spiked arrangements of two 

 or more flowers of grasses, which 

 are variously disposed round a 

 common axis. 



Spine, a stifl", sharp-pointed process, 

 containing some portions of woody 

 tissue, degenerated branch, leaf, 

 stipule, etc. 



Spinous, bearing or covered with 

 spines. 



Spongy, having the cellular tissue 

 copious, forming a sponge-like 

 mass. 



Spreading, having a gradual out- 

 ward tendency, or bending from 

 an axis. 



Spur, a tubular expansion of some 

 part of a flower. 



Spurred, having a spur. 



Stamen, that organ of the flower 

 which contains the pollen. 



Staminate, bearing stamens ; usually 

 applied to unisexual flowers. 



Standard, the dorsal petal in a pa- 

 pihonaceous flower. 



Stellate, disposed in a radiating 

 manner round a centre. 



Stigma, that portion of a pistil, 



generally its summit, by which the 

 fertilizing influence of the pollen 

 is conveyed to the ovules. 



Stigmatic, of or belonging to the 

 stigma. 



Sting, a sharp, somewhat stiff" hair, 

 seated on a gland which secretes 

 an acrid fluid. 



Stipule, a foliaceous appendage, va-

 tioles. 



Striated, marked with streaks or 

 little furrows. 



Style, the shaft which, in most 

 flowers, is interposed between the 

 stigma and ovary. 



Suh, in composition, somewhat ; im- 

 plying a near approach to the con- 

 dition indicated by the term with 

 which it is joined : thus, suh- 

 rotund is roundish. 



Subulate, awl-shaped. 



Sticculent, having abundant cellular 

 tissue, replete with juices. 



Suckers, tubercular processes on the 

 stems of certain flowering para- 

 sites, by which they imbibe nou-

 they attach themselves. 



Superior, placed above another or- 

 gan; applied especially to indicate 

 the position of the ovary with 

 respect to the calyx. 



Sword-shaped, straight and flat, with 

 the point acute.

 those of another in number, as in 

 a flower which has five sepals, 

 five petals, five or ten stamens, etc. 



Syncarpous, bearing fruit composed 

 of cohering carpels.
