The /Hippeastrum:of which a plate is given here was 
discovered by Mr. H. J. Elwes in 1902 near Lake Nahuel- 
Huapi on the Rio Limay in Argentina. The upper 
reaches of this river, where /7. Elwesii grows, are in a high 
dry valley with a cold winter climate and with a vegeta- 
tion quite different from that met with at similar alti- 
tudes on the Chilian side of the Andes. A plant brought 
to England by Mr. Elwes flowered in his garden at 
Colesborne in September, 1903, and the scape then pro- 
duced forms the main part of the present figure. The 
plant flowered again in September, 1914, and from 
material then supplied the plate was completed. In 
the genus /Tippeastrum, H. Elwesii seems very distinct 
in the ultimately spreading perianth-lobes. It _is 
perhaps most nearly allied to H. Ananuca, Phil., originally 
described from specimens collected at Caldera in the 
province of Atacama, but is readily distinguished from 
that species by its uniformly pale yellow perianth-lobes 
with the tube claret-coloured inside; in //. Ananuca the 
lobes though yellow elsewhere have vivid red midribs,
