AVH map***

This taxon is characterised by the coarse recurved hairs on stems, petioles and usually leaf surfaces, causing plants to be quite rough to touch, and in having a thickened tapering taproot which is never napiform as found in G. solanderi. Hairs on leaf surfaces may be somewhat tuberculate, a feature known to occur occasionally in G. homeanum.
