 Cyrill. has small homogamous fls. that fert. themselves in absence of 

 insects; it flowers all the year, and in winter (? on account of weak 

 light, cold, &c.) is often cleistogamic. The number of sta. is most 

 often 3, but varies a good deal. The fls. of S. graininea L. are larger 

 and protandr. , but with autogamy, whilst in S. Holostea L. the fls. are 

 still larger and very protandr. with little self-fert.

Stem, the leaf-bearing part of the pi. ; stem and leaf should always be 

 described together for the sake of accuracy and conciseness. Stems 

 may be annual, biennial, or perennial; erect, climbing, twining, 

 prostrate or procumbent, creeping, ascending or decumbent (bending 

 upwards from a prostrate base), floating, &c. ; they may be un- 

 branched (simple] or branched (describe mode of branching) ; if branched 

 they may be caespitose (a tuft of shoots from the base, as in many 

 grasses), fastigiate (many branches parallel to the stem, as in Lombardy 

 poplar), or \v\\\\fascicles (tufts) of lat. branches. The stem or branches 

 may be a corm, bulb, tuber, rhizome, runner, stolon, sucker, offset, 

 phylloclade, tendril, &c. Adnation may occur, or long and short 

 shoots ; the stem may be a monopodium or a sym podium ; it may be 

 'condensed' bearing 'radical' leaves, and run out into a scape bearing 

 only the fls., as in dandelion. It may be herbaceous (not woody above 

 ground), woody, succulent or fleshy; solid, hollow (fistular if herba- 

 ceous); straight, flexuose (zigzag) &c. ; cylindrical, terete (cylindrical
