Discovered by Coulter in California, and subsequently 
collected by David Douglas, in 1833, in New California, but 
unknown to me from any other locality and collector, except 
from a mention of the plant in one of the Reports of the 
United States’ surveys, quoted above, where it is stated to be 
found on hill-sides in the Grass Valley, California, together 
with a large-flowered variety (how large it is not said), and 
longer pedicels (one inch) at the Corte Madera, also in Cali- 
fornia. It is a very little known plant, being omitted in Klatt’s 
monograph of the genus, (published in the Linne, vol. xxxiv.), 
and is closely allied to 8. Zongipetala (Tab. nost, 5298), which 
is, however, a very much larger species, with a remarkably 
short perianth-tube. I am indebted to Messrs. Veitch for the 
specimen here figured, which flowered in his nursery last year. 
Derscr. Rhizome as thick as the little finger, creeping. 
Leaves a foot to a foot and a half long, by half to three- 
quarters of an inch in diameter, of a dark green colour, except 
at the bases and on the sheaths, which are paler, variegated 
with red, narrow-linear, gradually contracted into the acumi- 
nate tip, nerves obscure. Spathes usually two, enclosing 
FEBRUARY Ist, 1874.
