110 PRACTICAL BOTANY. 



Spicate, or Spiked : arranged in a spike. 



Spike: a sort of centripetal inflorescence, with the flowers arranged 

 along the sides of the axis. 



Spikelet : a secondary or partial spike ; the inflorescence of grasses. 



Spine : a thorn. 



Spinescent: tipped by a thorn. 



Spinose: thorny. 



Spur: a projecting, slender appendage. 



Stamen: a fertilizing organ of the flower. 



Staminate : furnished with stamens, but destitute of pistils. 



Standard : the upper petal of a papilionaceous corolla. 



Stellate : star-shaped. 



Stemless : really, or apparently, without a stem. 



Stekile : imperfect, barren. 



Stigma : the glandular part of the pistil, which receives the pollen. 



Stigmatic : bearing accommodations for receiving the pollen. 



Stipel : the stipule of leaflets. 



Stipellate : furnished with stipels. 



Stipulate: furnished with stipules. 



Stipule : an appendage at the base of certain leaves on each side. 



Strap-shaped : long, flat, and narrow. 



Strobile : the conical or oval fertile spike or catkin of Conifers, and 

 also of the Hop, Hop-Hornbeam, etc., in fruit ; a sort of aggregate 

 fruit. 



Style : the stigma-bearing, usually slender and tapering part of the 

 pistil. 



Sub- (prefixed to a descriptive term) : somewhat, slightly ; as in sub- 

 cordate, subsessile. 



Submersed : growing under water. 



Subulate: awl-shaped. 



Succulent : juicy. 



Suffruticose plants : undershrubs. 



Supra-axillary : above the axil. 



Suspended : hanging down. 



Suture : seam, particularly applied to the pistil. The line or seam 

 down its inner side, bearing the ovules, is named the ventral or 

 inner suture. An opposite line, running down the back of the 

 pistil, we call the dorsal suture. The ventral suture, forming a 

 projection or ridge in the cavity of the ovary, bears the ovules, and 

 is the placenta, which is double. A simple pistil is formed of a 

 floral leaf, with its edges carved inward and united; the junction 

 of the marprins is the ventral suture.
