GLOSSARY OF BOTANICAL TERMS. 



of the two kinds of spores produced by the 

 Selaginellas and Quillworts are called 

 microspores, and the larger, macrosjiores. 



Sporidium. — A spore produced on a pro- 

 mycelium. 



S poriferous. — Spore-bearing. 



Sporogenous. — Spore-producing. 



Sporocarp. — A term applied to the matured 

 product of the fertilization of the carpogo- 

 nium. 



Sporogonium. — A name applied to the spo- 

 rocarp of the Mosses. 



Sporophore. — The part of a sporogonium 

 that bears the spores. The plant which 

 in Bryophyta and Pteridophyta bears the 

 asexual spores, is also called the sporo- 

 phore. It is more properly called the 

 sporophyte. 



Sporophyte. — See Sporophore. 



Sporule. — A term applied to a minute 

 spore; also sometimes to minute granules 

 within a spore. 



Squamate. — Scaly. 



Squ ami form. — Scale-like. 



Squarrose. — Applied to stems or other 

 organs that are roughened with closely 

 arranged bracts or other spreading pro- 

 cesses. 



Stamen. — The pollen-bearing organ of the 

 flower, when complete, consisting of a stalk 

 or filament and a pollen-sac or anther. 



Staminate. — Possessing stamens. Applied 

 to flowers which have stamens but not 

 pistils. 



Stameniferous. — Bearing stamens. 



Staminode. — A stamen-like organ; a rudi- 

 mentary or imperfectly developed stamen. 



Stellate. — Star-shaped, or with parts ra- 

 diating from a centre, as stellate stigmas, 

 stellate hairs, etc. 



Stereom. — That part of a fibro-vascular 

 bundle whose main function is to impart 

 strength to it. 



Sterigma (//. Sterigmata). — A stalk 

 from which a spore or a spermatium is 

 separated by abjunction. 



Sterile. — Unproductive. A sterile flower 

 is one which does not possess a pistil, or 

 that cannot produce seed. 



Stigma. — That portion of the pistil which 

 receives the pollen. 



Stigmatic. — Belonging to the stigma. 



Stite, or Stipes. — The stalk of a Fern leaf; 

 also applied to the stalk possessed by some 

 pistils. In Fungi, the stalk which bears 

 the pileus. 



Stipitate. — Possessing a stipe. 

 Stipular. — Belonging to stipules. 

 Stipulate. — Possessing stipules. 

 Stipule. — One of the blade-like bodies at 



the base of the petioles of leaves. 

 Stolon.— A branch which bends over and 



strikes root. 

 Stolon I ferous. — Stolon -bearing. 

 Stoma (//. Stomata). — A breathing-pore, 



or opening found in the epidermis of 



the higher plants. Stomata are usually 



most abundant on the under surface of 



leaves. 

 Stone-fruit. — The same as drupe, q. v. 

 Stramineous. — Straw-colored or straw. 



like. 

 Striate. — With fine longitudinal lines. 

 Strict. — Upright; straight. 

 Strigose, or Strigous. — Armed with 



sharp and stout appressed hairs. 

 Strobile — A multiple fruit in whii h the 



seeds are enclosed by prominent scales, 



as a Pine cone. 

 Stroma. — A body composed of compactly 



arranged hyphse, on which sporocarps are 



borne. 

 Strophiole. — The same as caruncle, q. v. 

 Struma. — A wen-like appendage or swell- 

 ing. 

 Strumose, or Strumous. — Swollen on 



one side; possessing a wen-like protuber- 

 ance 

 Style. — That portion of the pistil which 



connects the ovary with the stigma. 

 Stylopodium. — A disc-like enlargement 



occurring at the base of the style in some 



flowers. 

 Suberin. — Cork-substance, a modification 



of cellulose; the same as cutin, q. v. 

 Suberous. — Corky; belonging to cork. 

 Submerged. — Applied to organs that grow 



immersed in water, as submerged leaves, 



etc. 

 Subulate. — Awl-shaped. 

 Succulent. — Thickened and juicy. 

 Sucker. — An ascending or erect branch 



from a creeping, underground stem. 

 Suffrutescknt. — Applied to a stem which 



is slightly shrubby at the base only.

or low shrub. 

 Sulcate. — Having furrows or grooves. 

 Surculose. — Bearing suckers. 

 Surculus. — A sucker. 

 Superior. — Applied to an ovary that is not 



at all adherent to the calyx. Also applied
