H ab . Barren sands of the Columbia, near Lewis and Clarke’s River. Douglas. About Carlton House
Fort. Dr. Richardson.— One of the most beautiful speeies, with white flowers of the size of those of Atv-
chusa officinalis. All the spikes are not, as said in Nuttall’s description, bifid, but (according to
my specimens) only the superior ones; the inferior ones are simple. In the description now referred to,
the bractes of the spikes are not mentioned, which are linear, hispid (hispidissimm); the inferior ones of
the length of the calyx. The inflorescence is rather a spica terminalis composita e spiculis altemis ap-
proximatis simplicibus bifidisque, than what is called spica? axillares, which becomes more evident since the
leaf at the base of the spikelets (quite of the same structure as the stem-leaves) is not affixed to the stem,
but at the branch of the spike.
