P. viscosa, Jacquini, decumbens, & fusco-maculata (Rouville) Dun. in DC.-Shore of Virginia? and N. Carolina to Florida. The species was no doubt founded on the Buenos-Ayrean plant, and it is not clear that Linnæus ever had it from "Virginia." The plant of our coast, if I mistake not, was what Linnæus, in appendix to the second edition of Species Plantarum, named P. Pennsylvanica, although he does not pretend to have it from Pennsylvania, and it is not found there. His herb. specimen is "Hort. Ups." I find nothing to distinguish the broader-leaved North American plant from the South American; and the range is not very uncommon for a sub-maritime species. The name alludes to the viscous berry: the herbage is not viscid. In the Manual I inadvertently applied the name of P. viscosa to a viscid-leaved species, P. heterophylla of Nees.

IV. Characters of various New Species.

RANUNCULUS OXYNOTUS. Glaber, perennis; rhizomate brevi fibroso multicipiti caules laxos 4-5-pollicares 1-2-foliatos 1-2-floros proferente foliis radicalibus confertis subreniformibus nunc cuneato-rotundatis, crenato-5-9-lobatis longius petiolatis, caulinis subsessilibus late cuneatis 3-5-fidis, lobis oblongo-lanceolatis; petalis sæpe 6 obovatis basi cuneatis aureis sepalis pilosis multo majoribus; receptaculo primum ovato demum cylindraceo crasso; carpellis perplurimis lævibus semiorbiculatis compressis dorso acutissime carinatis stylo brevi subulato subrecurvo acuminatis. California, near summit of Castle Peak, Sierra County, at 9,000 feet, J. G. Lemmon. Radical leaves much crowded: petioles about 2 inches in length; the blade less than an inch in diameter. Peduncles 2 or 3 inches long. Sepals and petals deciduous; the latter 3 or 4 lines long, 2 lines broad, deep yellow; scale at base of the claw conspicuous. Head of carpels 3 lines long in flower; in fruit half an inch long, the apparently fleshy cylindraceous receptacle smooth and hardly areolate. Ripe carpels a line long, much compressed, glabrous or occasionally with a very few scattered deciduous hairs, acute-edged both dorsally and ventrally, the dorsal margin conspicuously carinate, twice the length of the subulate flattened style. A strongly marked species, allied to R. Eschscholtzii and R. nivalis.

RANUNCULUS LEMMONI. R. alismæfolio proximus, subacaulis, inferne villoso-pilosus; foliis lanceolatis linearibusve integerrimis; pedunculis scapiformibus prælongis (spithamæis) simplicissimis; petalis spathulatooblongis parvulis; carpellis pubescentibus turgidis submembranaceis rostro brevissimo subulato inflexo apiculatis in capitulum depressoglobosum digestis.-Sierra Valley, California, alt. 5000 feet, J. G. Lemmon. Petals 3 or 4 lines long, narrow, deep yellow. Sepals tardily deciduous. Mature head of fruit 3 lines high, but 4 lines broad; the turgid and somewhat vesicular carpels 1 to 2 lines in length.

CORYDALIS CASEANA. Procera (2-3-pedalis) e radice perenni, ramosa; foliis bi-tripinnatis subglaucis; foliolis obovatis oblongisve mucronatis plerisque integerrimis imis subpetiolulatis, ultimis decurrenti-confluentibus; racemis erectis densifloris nunc paniculatis; bracteis plerumque linearibus pedicellum brevem vix superantibus; corolla alba apice cærulescente, calcare crasso recto obtusissimo horizontali vel adscendente; capsula ovali-oblonga turgida lævi stylo gracili subæquilongo superata; seminibus lævibus turgidis.—Sierra Nevada, California, first detected at the "Big Spring" in Big Meadows, Plumas Co., by J. G. Lemmon and Prof. E. L. Case, named in honor of the latter at Mr. Lemmon's suggestion. [It appears that it was several years ago detected by the indefatigable Bolander on Truckee River, near Truckee.] This remarkable species is related to C. Scouleri of Oregon. It has a similar capsule, abruptly tipped with a long style and a large stigma. The spur is nearly as long (about half an inch, and double the length of the rest of the flower), but not at all tapering. The corolla is said to be "creamy-white, with pale blue tips." The leaflets are only half an inch in length and are mucronately pointed.

STAPHYLEA BOLANDERI. Foliolis 3 late ovalibus vel orbiculatis parum acuminatis; petalis ex ungue latissimo modice spathulatodilatatis; genitalibus exsertis. - Banks of St. Cloud River, Shasta Co., California, Bolander, April, 1874. Besides the points mentioned in the character, which clearly distinguish this from our S. trifoliata, the more filiform filaments are quite glabrous; these and the long styles project conspicuously, being almost twice the length of the petals. Fruit not seen. We have now five species, rather equably dispersed round the world in the northern temperate zone, one eastern and one in Western North America, one in Japan, one in the Himalayas, and one in Europe. Dr. Bolander's name is already associated with many a Californian plant discovered by him. I am glad to have it commemorated by this interesting shrub.

ASTRAGALUS PULSIFERI. PHACA, Inflati: multicaulis e radice perenni, villosus; caulibus decumbentibus subpedalibus perplurimis; stipulis liberis subulatis: foliis 5-11 obovato-cuneatis sæpius emarginatis subconfertis; pedunculis 3-5-floris folio plerumque brevioribus ; pedicellis tenuibus bractea subulatæ æquilongis; calycis longe laxe villosi dentibus lineari-filiformibus tubo campanulato duplo longioribus; corolla alba purpureo tincta, vexillo apice bilobo; legumine haud stipitato ovato acuto pubescente membranaceo vesicario 5-8-ovulato 3-5spermo suturis haud introflexis uniloculari. prorsus Sierra and Plumas Counties, California, Mrs. Pulsifer-Ames and Mr. J. G. Lem

mon.

Leaflets about 3 lines, flowers 3 or 4 lines, and legume about half an inch in length. The legume refers this well-marked species to the Inflati section, but it has no particular resemblance to any other species. I wish it to bear the name of one of the two valued correspondents who discovered and communicated it, namely, Mrs. PulsiferAmes, to whom and to Mr. Lemmon we are mainly indebted for our knowledge of the botany of Sierra and Plumas Counties in the northern part of the Sierra Nevada.

PRUNUS (EMPLECTOCLADUS) FASCICULATA. Emplectocladus fasciculatus Torr. Pl. Frem. in Smiths. Contr. p. 10, t. 5. To this (notwithstanding the more marked presence of a style and the ovules not really suspended from the summit of the cell) I venture to refer a flowering specimen collected in the northern part of Arizona by Dr. Newberry, fruiting ones collected in the southern part of Utah (at St. George) by Dr. Palmer, in 1871, and both flowering and fruiting ones from the latter district, no. 56 of Dr. Parry's collection in 1874. A thin disk lines the tube of the short-campanulate calyx up to the origin of the calyx teeth, the edge of which is slightly free or salient. The flowers in the specimens at hand appear to have a sterile ovary, but in most cases surmounted by a rather slender style longer than it. Dr. Torrey's figure appears to represent a fertile ovary; but our fruit shows a style a line and a half in length. Otherwise Dr. Torrey's Emplectocladus seems to be identical with the plant before us, and it came from the same district. The fruit is globular, 5 or 6 lines long, hirsute-tomentose; sarcocarp very thin, in the dry state coriaceous: putamen globular, smooth, and even, neither suture prominent. Leaves involute-conduplicate in vernation. Having recently been favored with a fragment and flower from Dr. Torrey's original specimen of Emplectocladus, the suspected identity is verified. This name may now be appropriated to the group of American species of which I had referred, one to Amygdalus, and others to Microcerasus of Webb, but which form a well-marked section by themselves.*

IVESIA WEBBERI. Humilis, laxe villosa; foliis plerisque radicalibus, lamina circumscriptione oblonga petiolo filiformi breviore, foliolis approximatis quasi-verticillatis nempe sessilibus 2-5-partitis, segmentis linearibus integerrimis rarove bifidis; scapo decumbente spithamæo versus medium foliis 2 oppositis paucifoliolatis instructo; cyma confertiflora folioso-bracteata; pedicellis demum calyce longioribus; calycis segmentis accessoriis linearibus (raro bipartitis) vera haud æquantibus; petalis flavis oblongis demum lanceolatis basi attenuatis vix unguiculatis calycem adæquantibus; staminibus 5 oppositisepalis (nunc 2-3 oppositipetalis additis); filamentis demum petala subæquantibus subulato-filiformibus; carpellis 3-4; stylis parum lateralibus. In ravines, &c., Sierra and Indian Valleys, California, at elevation of about 5,000 feet, Dr. Webber, J. G. Lemmon. A neat and very distinct little species, most resembling I. unguiculata in the leaflets; but these are crowded on an inch or less of the rachis, and the villosity is less dense and silky; also the petals smaller and bright yellow. It was first found near the residence of Dr. Webber, the owner of Webber Lake, a gentleman much interested in natural history, and who has efficiently furthered botanical research in the very interesting district in which he is almost the oldest settler. Wherefore this new species may most appropriately bear his name.
