Corolla-lobes lanceolate, much longer than the anthers.— Only three specimens seen. 
*** Stem prostrate with many subequal pairs of thick distichous leaves, 
one of each pair very large, the other very small.—lTabit of Elatostemma, 
anthers with long beaks. 
14. A. Blatostemma, Hook. f.; stem umbel and leaves beneath fur-

Stem 6-8 in., prostrate, very robust, simple or branched, sometimes rooting at 
the nodes. Leaves 6-8 pairs, larger 2-21 in., coriaceous ` nerves about 10 pair, united 
by very stout retieulating nerves.  Peduncle softly tomentose. Flowers 3 in. diam.

1 —This species singularly resembles an Elatostemma in habit.
