66 PITTONIA. 
subcordate at the base and subsessile, at apex acute, though 
scarcely mucronate, white-veiny above, beneath very pale and 
with an obvious though scattered pubescence of short curved or 
curled stiff white hairs, the margin beset with remote but not 
minute scabrous points; rameal foliage the same, but only half 
as large; all the branchlets ending in a few-flowered cyme: 
sepals ovate, spreading: corolla white; not strictly cylindric, 
even the tube widening slightly upwards. . 
An excellent species, with its own peculiar leaf-outline (the 
leaves almost sessile) and a pubescence as peculiar. The ovate 
sepals another excellent mark. The only specimen seen i8 
Mr. Wooton’s n. 113. from the Oregon Mountains, New Mexico, 
1897. 
A. RHOMBOIDEUM. Alliec to A. androsemifolium, quite as 
large, stouter, canescent with a minute subtomentose pubescence: 
leaves mostly rhombic-ovate, 2 inches long, 14 inches broad in — 
the middle, prominently mucronate and petiolate; branches all 
incurved, their leaves deflexed, the cymes borne conspicuously 
above them and rather many-flowered: sepals pubescent, wine- 
colored, of triangular-lanceolate or properly lanceolate outline 
and acuminate, of rather more than half the length of the rose- 
red corolla-tube, this broad-cylindric, the oblong-ovate segments 
rather deep and recurved. 
This truly excellent species, though a strict ally of A. andro- 
semifolium, was permitted by me to pass for a state of my 
A. vestitum (which is of the A. cannabinum group) in writing — 
the Bay-Region Manual. The plant is known only from Napa 
Valley, California, where it was collected by Mr. Jepson, east of 
the village of St. Helena, in 1893.
