914 PITTONIA: 
dark-purple spots next the andreecium : androecium about 3 
lines long, filaments connate, the tube dark-purple, the ornate 
exterior of each filament changing to yellow at the base of | 
the anther and continued up the back of it nearly to the 
apex in a lanceolate form and lying in irregular folds ; anthers 
otherwise purple, not quite twice the length of the stamineal 
tube, slightly divergent around the moderately exserted pistil, 
retuse at the rather blunt apex: capsule oblong, circum- 
scissile at top: seeds reddish-brown, somewhat cubical, the 
testa sinuously reticulate. 
e common species on dry hills and mesas in the southern 
part of California, about San Diego and San Bernardino. It 
is confused with D. Jeffreyi in the Revision. It agrees with 
that species in root character and in the attitude of its foliage, 
but is totally distinct; for that species belongs to the high 
mountains of California and Oregon, the climate and soil of 
which are as unlike what are found in southern California as 
can well be imagined; and its capsule opens really by valves, 
not by an operculum. But the most striking peculiarity of 
D. Clevelandi is, that notwithstanding the excessively long 
period of drought its roots have to endure in that climate, 
they do not change to tubers, but are perfetly and normally 
renewed before the beginning of the long summer, remaining 
shrivelled and dormant until autumn, and are found firmly 
attached to the crown even in the midst of the long summer 
drought. This fact I first observed in specimens (if they be 
of the same species) which I collected in fruit, in August, 
on Santa Cruz Island. The more recent study of the plant 
has been made, with Mr. Cleveland’s intelligent and invalu- 
able assistance, during the past year; he having communicated 
living plants in abundance, at different stages of growth and 
maturity. Excellent herbarium specimens from near San 
. Bernardino by Mr. Parish will probably be found supple- 
menting those of Mr. Cleveland in the various herbaria.
