BOTANY.

since Endlicher’s name of Anoplanthus has been adopted by Reuter, the monographer of the 
order in De Candolie’s Prodromus, while Nuttall has preferred the prior claim of his unobjec¬ 
tionable name Gymnocaulis, there can be no question of the propriety of restoring the far older 
name of Aphyllon, under which Mitchell characterized the genus more than a hundred years 
ago. There is considerable reason for thinking, however, that the genus will be reduced to a 
mere section of Phelipaja. 
SCROPHULARIACE2E. (By A. Gray.) 
Linaria Canadensis, Dum. Near San Francisco, and elsewhere in California; April. A 
species diffused over all the temperate parts of the American continent. 
Scrophularia nodosa, Linn.; Benth. in DC. Prodr. 10, p. 309. Corte Madera and Napa 
Valley ; April. species common to the temperate portion of the whole northern hemisphere. 
Collinsia BARTSiiEFOLi a, Benth. in DC. Prodr. 10, p. 318. Bolinas bay and Punta de los 
Reyes, California ; April. 
Collinsia tinctoria, Hartio.; Benth. PI. Hartio. p. 328. Wet ravines, Knight’s Ferry, etc., 
California ; May. This and the foregoing are likely to pass into the next. 
Collinsia bicolor, Benth. in Hort. Trans. 1, p. 480. Hill-sides, Martinez, Mokelumne, etc., 
California; May. 
Collinsia parviflora, Dougl. in Bot. Beg. t. 1082. Hill-sides, on tbe Yuba; May. Var. 
Sparsiflora, Benth. (C. sparsiflora, Fiscli if Meyer.') Corte Madera, Napa Valley, and mount¬ 
ains, near Oakland, California ; April. The corolla is not only larger, but longer in proportion 
to the calyx ; still intermediate forms appear to connect it with C. parviflora, as Bentham states. 
Pentstemon centrantiiifolius, Benth. Scroph. Ind. p. 7, & in DC. Prodr. 10, p 323. Plains, 
near San Gabriel, California; March. 
Pentstemon microphyllus (sp. nov.): fruticosus, ramosissimus, foliis in axillis crebre fasci- 
culatis (minutis) obovatis ovatisve obtusissimis coriaceis integerrimis subpetiolatis ; racemis 
paniculatis; sepalis fructiferis oblongo-ovatis. On Williams’ Fork of the Colorado, New 
Mexico. The specimens were collected in February, and are without flowers, but they bear the 
remains of the fruit of the preceding season. The plant is a remarkable one, and may possibly 
not belong to tbis genus. The leaves are only one or two lines long, of a thick and Arm 
texture, and arise three or seven together from short spurs or undeveloped branches. The 
peduncles are opposite and alternate, somewhat spreading, and about as long as the fructiferous 
calyx. There is nothing peculiar about the capsule ; and the aspect of the plant is that of the 
section Erianthera. 
Pentstemon Lewisii, Bentli. 1. c. ? Rocky ravines, Cajon Pass, California ; March 16. The 
specimen belongs to a shrubb species, and bears only the vestiges of the last year’s fruit. The 
leaves are not so finely and evenly denticulate as those of P. Lewisii; but for the present it may 
be referred to that species. 
Pentstemon breviflorus, Lind. Bot. Beg. t. 1946. Knight’s Ferry, on the Stanislaus; May. 
A shrubby species, as already noted by Hartweg. 
Pentstemon heterophyllus, Lindl. Bot. Beg. t. 1899. Butte mountains, near Marysville, 
California; May. The variety with narrower sepals, without manifest scarious margins, ( Hoolc. 
& Am. Bot. Beech.;) the same as Hartweg’s No. 1880, and not to be well separated from P. 
azureus, Benth. PI. Hartio. No. 1819, which seems, as to the calyx, to connect all the forms. 
Pentstemon spectabilis ( Thurber in A. B. Gray’s Bep. ined.) : undique glaber ; caule stricto 
elato (3-4-pedali) herbaceo ; foliis coriaceis serraturis rigid is crebris argute dentatis oblongis 
seu ovato-lanceolatis ssepius acutis, imis sessilibus, reliquiis connato-amplexicaulibus, superior- 
ibus floralibusque orbiculato-disciformibus; panicula ampla elongata virgato-pyramidali; 
pedunculis 3-9-floris; sepalis orbiculari-ovatis carnosis ; corolla e tubo brevi (calyce duplo
