Rhigozum obovatum bud

The bulging bud of Rhigozum obovatum is broadly tubular, the corolla lobes that will spread when open still folded unevenly in knobbly protrusions around its tip.

The funnel-shaped calyx is about as yellow as the corolla, its pointed lobes clasping the corolla base. The calyx is hairier than the corolla.

Some of the leaflets of the trifoliolate leaves have rounded tips, others are notched; all folding in along their midribs. The spur-branchlets from which the leaves grow are small, mere woody mounds upon the branches. In the photo the leaves appear simple, growing in threes on shortish red petioles from the stem cushions (Coates Palgrave, 2002).
