section, [sect.]: (1) (bot.) a category of taxa intermediate in rank between<br />
subgenus and series. (2) (zool.) a rank that if treated as a division of<br />

used in identification (e.g. Dicranum fuscescens Sm. 1804 sec.<br />
Ludwig et al. 1996); when used to indicate different<br />
circumscriptions, use with a range of ideographs has been suggested<br />

all the bibliographic information required by the Code for valid<br />
