This is a small shrub
having a smooth but glutinous bark and can be of 2 m in height. The branches
are erect and are further divided into smaller branches that are round,
resinous and bear foliar scars. The leaves are oblanceolate to elliptical,
sometimes very largely elliptical and 3 to 7 cm in length by 1 to 3.1 cm in
width. They also have a strong turpentine smell. The leaf tip is pointed while
the base is cuneiform. The petiole is 2 cm in length, slightly canaliculated above
with a prominent vein below.
Acrodromous venation pattern is also observed. The leaf margin is rather entire on juvenile leaves and rather serrated on older ones. Terminal corymbform inflorescence of 7 cm in length having short, linearly elliptical bracts are also present. Campanulate capitula bearing white fragrant flowers, with short peduncles of 5 to 6 mm are also present. Involucre bracts can be divided into three groups. The external ones are oval to oblong, 1 to 2 mm in length. They are green but turn brown when glutinous. They are also glutinous and herbaceous. The middle ones are elliptical, 2.5 to 3 mm in length, pale green on the margins and purple at the tips. These turn pale brown when old. The midvein is darker and the bracts membranous. The internally found bracts are elliptical, 2 to 2.25 mm in length. The receptacle is 1.5 to 2 mm in diameter, rather flat and convex. The external flowers occur in bunches of 18 to 26. The corolla is filiform, 2 to 2.5 mm in length. The internal flowers are in groups of 12 to 20. The tubular corolla is 3 mm long. They are yellowish brown in colour, and sometimes tinged with purple. The ovary is reduced to the size of a nipple. Achenes are obconic, pale brown, and 1 to 1.2 mm in length. The pappus is white and 2 to 2.25 mm long. |
