Leaves 8 in a wliorl on the main stem ; 6 on the branches,
linear, scarcely at all lanceolate, destitute of veiny reticulations,
smooth on both sides, the edges rough, especially
towards the point, with sharp, shallow serratures, or close
bristles, hardly more than a simple, strictly marginal row,
pointing forwards. Panicles terminating the stem and
upper branches, 3-forked, corymbose; the upper ones aggregate.
Stalks quite smooth. Corolla white, larger than
in G. erectum, with horizontal segments, each tipped with a
short, taper, not bristly point, various in length and direction.
Stigmas globular, large. Fruit smooth- or slightly
granulated.”
The points in which this differs from G. erectum, its next
akin, appear to be the smooth stem, the smaller number,
linear form, and smoother margins of the leaves, which
also are free from the reticulations conspicuous in G. erectum,
the less dense inflorescence and the less elongated
points of the segments of the corolla. “ Experience must
prove how far the differences above indicated are constant,”
and we hope the figure given from the original specimen
will assist in the inquiry.—J. D. C. S.
