98. H. occultans, Welw. ex Reichh. f. in Floi-a, 1865, 178. Plant 

 14—2 ft. high. Leaves cauline, oblong-lanceolate, acuminate, 2-4 in.

 descending into the bracts. Stigmatic processes stout, obliquely capitate, 

 2 lin. long. Anther channels free from the side lobes of the rostellum, 

 linear, 2| lin. long. Rostellum with subulate, incurved side lobes, which 

 are hooked near the apex and 3| lin. long ; front lobe linear, obtuse, 1 J 

 lin. long. — Kranzl. in Engl. Jahrb. xvi. 93.

 Lopolla, Welwitsch, 737 ! and without precise locality, Antnnes, 15 ! 



A remarkable species. Neither Reichenbach nor KrJinzlin correctly describe the 

 petals, and the latter makes no mention of the remarkable side lobes of the rostellum.
