Seedlings

Cotyledons fleshy, linear-spathulate. First pair of leaves compound, leaflet margin +/- serrate, compound leaf rhachis ending in a narrowly spathulate appendage. At the tenth leaf stage: leaflet blades unequal-sided particularly towards the base, midrib raised and hairy on the upper surface; compound leaf rhachis ending in a hairy, awl-like appendage at the apex.
