[SECTION Pentadelphous (five brotherhoods), when in five sets, as in some species of Hypericum and in American Linden (Fig. 277, 289). Polyadelphous (many or several brotherhoods) is the term generally employed when these sets are several, or even more than two, and the par- ticular number is left unspecified. These terms all relate to the fila- ments. Syngenesious is the term to denote that stamens have their anthers united, coalescent into a ring or tube; as in Lobelia (Fig. 285), in Violets, and in all of the great family of Compositae. 284. Their Number in a flower is commonly expressed directly, but sometimes adjectively, by a series of terms which were the name of classes in the Linnsean artificial system, of which the following names, as also the preceding, are a survival: — Monandrous, i. e. solitary-stamened, when the flower has only one stamen, Diandrous, when it has two stamens only, Triandrous, when it has three stamens, Tetrandrous, when it has four stamens, Penta?idrous, when it has five stamens, Hexandrous, when with six stamens, and so on to Polyandrous, when it has many stamens, or more than a dozen. 285. For which terms, see the Glossary. They are all Greek numerals prefixed to -andria (from the Greek), which Linnaeus used for andrcecium, and are made into an English adjective, -androus. Two other terms, of same origin, designate particular cases of number (four or six) in con- nection with unequal length. Namely, the stamens are Didynamous, when, being only four, they form two pairs, one pair longer than the other, as in the Trumpet Creeper, in Gerardia (Fig. 203), Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray, Asa, 1810-1888.
