Flowers hanging down at night. Linn. Stalks (scarcely a span high, E.) 
smooth after flowering, hairy when young. Leaves (all radical, forming 
a star on the ground, E.) sometimes entire. Flowers white, when in 
blossom in broad-topped spikes, about fifteen in each. It is difficult to 
find the full compliment of stamens when the flower is fully expandedi as 
they drop when the germen begins to enlarge.

Leaves almost all radical, spear-shaped, bluntly toothed, or waved at the 
edge, fringed, sometimes hairy underneath. Stem from ope to three or 
four inches high, upright, simple, cylindrical, slightly hairy, frequently

panding, hairy. Petals scarcely notched. 
D. stellata of Jacquin, to which this plant was referred in the fourth edition 
of our work, differs in many respects. On re-examining our specimens, 
we find that Mr. Brown originally named those gathered and communi¬ 
cated by himself {e D. hirta of Linn.” E.)

from which it derives its English name, must remain doubtful. It is about the earliest of 
our flowering plants, and though insignificant in itself, as an humble harbinger of the?
