seeded, but the walls hyaline, adherent to the seeds and 
breaking irregularly, not by the sutural lines which are 
apparent but do not become lines of actual dehiscence. 
* * Capsule of firm texture, opaque, more or less perfectly 
dehiscent ; seeds not agglutinate in a mass. 
+ Leaves glabrous, setaceously multifid, but soft and in- 
nocuous ; only the floral bracts pungent ; 
herbage scentless. 
6. N. corTULEFOLIA, Hook. & Arn. Bot. Beech. 368; Benth. 
in DC. 1. e: gochloa cotulefolia, Benth. in Bot. Reg. 
l.c.: Gilia cotulefolia, Stendel, 1. c.; Gray, ll. ec. excl. N. 
pubescens.—The flowers in this well marked species are 
tetramerous and the four segments of the calyx are all entire. 
two of them being of twice the size of the others. The 
corollas are white and the stamens well exserted. The species 
is common on the plains of the lower valley of the Sacra- 
mento, particularly about Suisun. I have also a specimen 
from Mr. Hickman, obtained by him near Gilroy, south of the 
Bay of San Francisco. The foliage is sufficiently like that of 
Anthemis Cotula in aspect, but is wholly scentless. The 
ascribing té it the odor of the composite thus named has come 
of the confusing of this plant with the very different N- 
pubescens, which latter is a hundred fold more common and 
well known. 
T. N.NIGELLZFoRMIs. Habit of the last, the foliage some- 
what firmer but not pungent: flower-clusters conspicuously 
involuerate, the bracts broad and setaceously multifid: 5- 
merous: 2 larger calyx-segments aristate-pinnatifid, other 3 
with pungent teeth: corolla deep yellow, the funnelform 
throat with 5 purple or crimson spots : fruit unknown. 
Near Visalia, Tulare Co., California, April, 1886. Dr. T. J. 
Patterson. A very beautiful species, the large bright green 
and glabrous multifid bracts giving the effect of those which 
subtend the flower of Nigella damascena.
