Examples
“The grain is pale, brownish yellow, ellipsoidal-oblong, subacute, trigonous, rough and never smooth, with a shallow groove on the dorsal side; the embryo is about one-third the length of the grain.”
“The grain is oblong, obtusely trigonous, broadly and shallowly grooved dorsally with concentric minute tubercled ridges covered with a loose pericarp.”
“The racemes are usually two, erect, fragile, 1 to 3 inches long with a slight thickening of the peduncle below the inflorescence; the joints are 1/3 to 2/3 as long as the sessile spikelets; trigonous and subclavate, and with long hairs on one side.”
“It is very much flattened in _Paspalum scrobiculatum_, but somewhat trigonous in _Digitaria sanguinalis_.”
“_Spikes_ are 1/2 to 1-3/8 inches, sessile or shortly stalked; the _rachis_ of the spike is slender, trigonous and scaberulous.”
“The inflorescence consists of spikes, solitary, digitate or fascicled, articulate and fragile; the joints of the floral axis and the pedicels of the pedicelled spikelets are trigonous and hollowed ventrally.”
“The _spikes_ are numerous, greenish or purple tinged, slender, erect or spreading or sometimes deflexed, opposite, alternate or in fascicles of two to four varying in length from 1/4 to 2-1/2 inches; the _rachis_ of the spike is trigonous, flattened out ventrally and with a ridge on the ventral side and the margins are scabrid.”
“Grain is oblong, obtusely trigonous, or concavo-convex, red-brown and rugulose on the ventral side.”
“The _inflorescence_ is 1/2 to 3 inches long and consists of fascicles of spikelets; the rachis is trigonous, smooth, and flexuous.”
