Closed examination revealed that specimen from Bungo Range National Park has several distinguishing morphological characteristics, i.e., elliptic and oblong-elliptic leave with caudate apex, being bilobed with tomentose and black stripes at the margin of the ligule, orange flower, a widening cup-shaped stigma with cilia, and distinct trilobed (Table 1, Figures 2 and 3).
Type of Auricle and Relative Shape of Ligule. An equal proportion of the germplasm totally constituting 84% of the collection belong to four phenotypic classes, namely, those with no auricle and others with transitional and short and lanceolate auricles.
Another feature, the ligule, is an outgrowth that arises at the inside junction of the sheath and leaf blade.
Ligule pit apertures are clearly visible on Bothrodendron stems, thereby distinguishing them from the superficially similar stems Cyclostigma and Pinakodendron, in which they are never seen.
Entries include common and Latin names; generic descriptions; distribution; habitat; culm; leaf, sheath, and ligule; inflorescence and flower; and reproductive time; often comments; color photographs of whole plants and details; and sometimes additional drawings.
Leaves generally have well-developed blades, but are reduced to lobes in some species; there also may be a ligule. Inflorescences are capitate or anthelate.
Other important structures used for identification purposes, such as the ligule (Figures 4 and 5), collar (Figures 6 and 7), and auricles (Figures 8 and 9), are found at the collar area where the leaf sheath and blade join (Figures 10 to 13).
Identify the blade, ligule, sheath, crown, root, rhizome, and stolon, if present.

The morphometric variables used were plant height from ground level to the uppermost visible ligule, stalk diameter at the base of the plant, and maximum apical ear diameter at [R.sub.2].
He likes to use precise, sometimes scientific, terms like virga, ligule, and frazil, and to intermingle them with formal literary terms.
