T. biflora which 1 owe to Dr. Fiscuer, and those grown in 
the Botanic Garden here, might have left me in doubt 
whether they should be considered more than varieties. 
Among my own specimens, the distinction seems to rest 
chiefly on all the parts of the flower in Tuxra biflora being 
smaller, the petals less pointed, and the outer more nearly 
equal to the inner in breadth, and rather longer than they. 
I have had no means of judging as to the ripe fruit; the 
germen seems alike in the two. Tutrpa tricolor is a native 
of dry, stony places on the sides of the Altai mountains. 
T. biflora is from Astrachan. 
Descr. Bulb ovate, about the size of a filbert, covered 
with a brown skin. Stalk glabrous, erect, green, longer 
than the leaves. Leaves (five inches and a half long, three 
(or more) lines broad) two in the specimen described and in 
all the native specimens which I have seen, the upper one 
the narrowest, glabrous, glaucous, and slightly channelled 
in front, green and somewhat keeled behind, subacute and 
callous at the apex. Flowers suberect. Petals lanceolate, 
acute ; outer petals narrower and rather shorter, greenish on 
the outside, within white, and yellow at the base, every- 
where glabrous, striated ; inner petals (an inch and a quarter 
long, five lines broad) white, yellow at the base, ciliated at 
the claws, everywhere else glabrous, striated with faint, 
diverging lines, the middle rib being green. Stamens alter- 
nately longer, all about half as long as the petals, yellow; 
filament subulate, flattened, broadest above the base, and 
there hairy on the outside, narrower and nearly colourless 
below ; anthers oblong, erect, nearly equal in length to the 
shorter filaments ; pollen yellow, granules oblong. Pistil 
scarcely exceeding in length the shorter filaments, three- 
sided, pyramidal ; stigma of three obscure lobes. Ovules 
numerous, imbricated. Graham.
