‘Flowers handsome, straw-colored, specked with red.’’ Very scantily gathered, and in blos- 
som only, so as to throw no new light upon this rare and interesting plant, except that the 
limb of the expanded corolla appears as if nearly regular, the throat open, the lobes erose- 
denticulate at the obtuse summit, and abruptly cuspidate-pointed. But I have the good for- 
tune to possess the fruit, from a specimen gathered long ago by Coulter (Calif. coll. No. 616.) 
The ovate capsule has thin membranaceous walls, and is two-celled, with a thick axile placenta, 
covered with closely packed, slightly ascending seeds. The dehiscence, though not by regular 
pores, is essentially that of the Antirrhinee, so are the seeds, which resemble those of Antir- 
rhinum cyathiferum, Benth.; only more oval, and the incurved wing larger. The internal 
structure is the same. So the genus belongs to Scrophulariacew Antirrhinex.

PEDICULARIS CENTRANTHERA, Gray in Mex. Bound. Surv., p./26 High mesa west of Little

ANTIRRHINUM ? FILIPES, (sp. nov.:) diffasum ramorissimum, basi villosum, cet, glaberrimum - ; 
foliis oblongis lanceolatisne subintegerimis teneribus in petiolum attenuatis ; pedicellis sparsis 
issimis cum ramulis floribus filiformibus tortuosis ; floribus (ut videtur) minimis ; ; capsula 
istic: Desert arroyos. ‘‘Flowers white.’’ The Spvutia in the specimens scarcely larger 
than the calyx, its structure hardly to be made out in the spent specimens. Pedicels capillary, 
tortuous, from one to three inches long. Capsule 14 line in diameter.
