Oban, Ako-Aking Road; n. 971. 
A prostrate rooting herb, the ascending flower-bearing branches 
eventually rooting in their turn. Bladeof leaf usually 3-5 x 2:5-3:5cm., 
grey-green when dry, paler below and with an open network of pro- 
minent hairy nerves; petioles 1-1:5 (rarely up to 9:5) cm. long. 
Bracts about 10 x 7 mm. Bracteoles 8-10 mm. long, 1:75 mm. wide 
at the broadest part. Spikes usually 2-4 cm. long, on peduncles of 
1-2 em. Calyx about 29:5 mm. long. Tube of corolla 9 mm. long, 
3 mm. broad. Upper lip 7:5 x 8 mm.; lower lip 7 mm. long, the 
lateral lobes 4:5 x 2 mm., the middle lobe 4:5 x 8 mm. Filaments 
of front pair of stamens 4 mm. long, of hind pair 2mm. Anthers 
2 mm. long. Pollen-grains about 70 p in diameter (55-80 u). Ovary 
1:5 mm. long. Style 12 mm. long. Capsule not seen. 
The position of this very distinet genus is somewhat uncertain, 
but in view of all circumstances the neighbourhood of Lepidagathis 
would seem to be its proper location. It should be observed that the 
supposed slit on the inner face of the pollen-grains was not clearly 
made out.

Apparently a shrub with stoutish sparingly leafy branches. Blade

especially on the underside; petioles 1-3 cm. long, with the same 
clothing of very minute brown hairs found upon branches, leaves, &e.
