fortunately described the anthers as exappendiculate. This has led te 
some misapprehension as to its affinities, and it has been placed in the - 
Piquerinae by Hoffmann in Engl. & Prantl, Nat. Pflanzenf. Nachtr, 
zu iv. Ab. 5, 321 (1897), who seems to have overlooked Professor J. M. 
Holzinger’s wotes on the subject, Bull. Torr. Bot. Club, xx, 287, t. 160 
(1893). Careful dissection shows that the anthers are each provided 
with an ovate deeply retuse membanaceous apical appendage. This 
trait throws the genus into the Ageratinae, where it should probably 
be placed nearest Alomia, a conclusion long ago reached by Professor 
Holzinger.

Mr. Baker’s description of this species was drawn from Schomb 
no. 353 in the herbarium of the Royal Gardens at Kew. He 
that the plant is an erect doubtfully perennial herb. While at 
Royal Botanical Museum of Berlin, the writer had an opportunity t 
examine an authentic specimen of Caelestina repens Sch. Bip., mentioned 
in Schomb. Fauna et Flora, Guy. 1134 (1848), which proves identi 
with Baker’s species. Schultz’s name, although earlier, cannot be 
up, as it is accompanied by no description. It was founded on 8 
burgk’s no. 1188, collected on a moist savanna near the G 
Mountains, British Guiana. The specimen is more complete than 
one at Kew, and shows that the plant has a horizontal, ev 
perennial, and slightly lignescent rhizome, which roots at the 1 
and sends up erect subsimple stems.
