C. pauciflora, Nutt., of which I have a specimen in fruit, kindly sent to me by that excellent botanist, appears to be a form of this species with smaller leaves and flowers than usual. Dr. Parry also found it at San Diego, but with male flowers only. Seemann refers C. lasiantha to C. Peruviana, DC.

Dr. Parry collected it in the year 1850, and I have distributed specimens of it under the MS. name quoted above. Our plate was engraved before the figure in the Botanical Magazine was published.

Cañon of the Guadaloupe river, Sonora; Capt. E. K. Smith. A handsome shrub 5-10 (rarely 15) feet high, Leaves coriaceous and rigid; leaflets 1-21 inches long, sometimes truncate or cordate at the base, the middle one usually much longer than the others, and with more numerous teeth; the lowest pair situated close to the base of the petiole. On some specimens the primary leaves are reduced to small branching prickles, as in Berberis proper. Racemes 1-3 together; the pedicels 4-5 lines long. Flowers about as large as in the common Barberry. Filaments inappendiculate. Berries somewhat ovate, dark blue, about the size of currants. This species was first discovered by Frémont, in 1844, on the tributaries of the Rio Virgen, in southern Utah. It is nearly allied to B. trifoliata, but differs in the number of leaflets, longer racemes, and blue berries.

A tall branching plant, (3-4 feet high,) with showy golden yellow blossoms in panicles. It differs from Dicentra in the filaments of the two phalanges being united nearly to the summit, where alone they are distinct; in the dull verrucose horse-shoe-form seeds, which are thick on the margin, and destitute of a strophiole or crest; and, lastly, in a peculiar habit. The pollen is spherical, as in Dicentra. It may be considered as the type of a genus or subgenus, to which the name of Chrysocapnos would not be inappropriate.

Sandy hills near Monterey, California; May; Parry. The specimens are in flower and fruit. The siliques are an inch and three-quarters long, nearly two lines broad, and much compressed. Seeds narrowly winged, and sometimes partly in two rows. Cotyledons distinctly accumbent, although the radicle is, in some cases, slightly oblique. An original specimen of Nuttall's plant agrees exactly with ours, but it has only very young fruit. The ripe fruit and seeds have probably not been seen before.
