supremo tubo vix dimidio breviore; corollae tubo calycem bis terve superante, fauce valde 
ampliata, labiis subeequilongis; stigma obtuse bilabiato, labiis brevibus latis inæqualibus sed 
consimilibus ; fructu immaturo subgloboso. Low places, Mark West's creek; April, and Knight's 
ferry, on the Stanislaus; May. (Also communicated by Dr. Andrews, etc.) Flower fully as 
large as that of E. Douglasii, often an inch and a half or even two inches loug, lilac? the 
throat mottled with deep purple. Immature seeds apiculate at both ends. This is not the E. 
Coulteri, Harv. & Gray, in the herbarium of Trinity College, Dublin, (Coll. Coult., No. 614 :( 
but as no character of that has been published, and as recent specimens lead us to think it not 
different from E. Fremonti, the name should be retained for the present species, to which 
Bentham applied it, although we are not sure that it occurs in Coulter's collection. 
UNANUS BIGELOVII (sp. nov.): foliis caulinis oblongo-lanceolatis acutis; calycis subcampan- 
ulatis valde plicato-angulatis, ore vix obliquo, dentibus inequalibus triangulari-subulatis pun- 
gentibus dimidium tubi longitudine paullo excedentibus ; corolle tubo calyce subduplo longiore, 
limbo patentissimo, lobis æquilongis ; stigmate integro. Gravelly hills, near the Colorado of 
California; February 17. On the Mohave creek; March 2. Plant only beginning to blossom, 
1-2 inches high, doubtless attaining a greater height as the season advances. Largest leaves 
an inch long, more or less viscid-pubescent, like the stem. Calyx 4-5 lines long. Corolla 6-8 
lines long, of the same shape as in E. Fremonti ; the foliage and the calyx quite different. 
VERONICA AMERICANA, Schwein. ; Benth. in DC. Prodr. Santa Rosa creek, California; May. 
CASTILLEIA AFFINIS, Hook. & Arn. Bot. Beech., p. 154. Cocomungo, California; March. The 
. same as Hartweg's No. 1896. 
CASTILLEIA HISPIDA, Benth. in Hook. Fl. Bor.-Am, 2, p. 105. San Francisco and Punta de los 
Reys; April. 
ORTHOCARPUS PUSILLUS, Benth. Scroph. Ind., in DO. Prodr. 10, p. 535. Low grounds, San 
Francisco; April. 
ORTHOCARPUS FLORIBUNDUS, Benth. l. c. San Francisco, California ; April. 
ORTHOCARPUS ERIANTHUS, Benth. l. c. Benicia, California; April. 
ORTHOCARPUS LITHOSPERMOIDES, Benth. l. c. Mark West's creek, California; April. 
ORTHOCARPUS (TRrPHYSARIA) FAUCIBARBATUS (sp. nov.): foliis linearibus 1-3-nerviis ultra 
medium pinnatifidis cum caule erecto ramoso levi glabris, laciniis angusto-linearibus fere fili- 
formibus elongatis; bracteis viridibus scabro-puberulis floribus brevioribus; spicis demum 
interruptis ; calyce tubo corolle pubescente dimidio breviore, dentibus triangulari-lanceolatis 
obtusis vix dimidium tubi adeequantibus ; corolla labio inferiore trisaccato, fauce secus plicas 2 
palatinas longe barbata, appendiculis brevissimis obtusis; antheris unilocularibus. Corte 
Madera, California; April 20. Plant rather stout, 9 or 10 inches high, with spreading branches. 
Cauline leaves 2 inches long ; the bracts becoming shorter and broader, the upper ones nearly 
palmate. Flowers 7-8 lines long. Calyx minutely pubescent. Corolla apparently pale yellow. 
Allied to O. lacerus and O. lithospermoides of Bentham. The last named has the throat of its 
corolla somewhat villous-pubescent; that of the others is glabrous. Besides the smoothness 
and the one-celled anthers, the calyx distinguishes the present species. 
ORTHOCARPUS DENSIFLORUS, Benth. l. c. Corte Madera and San Gabriel ; March and April. 
ORTHOCARPUS CASTILLEIOIDES, Benth. l. c.? Corte Madera, California; April. Too young for 
proper determination. 
ORTHOCARPUS (ONCORRHYNCHUS) ATTENUATUS (sp. nov.): cinereo-pubescente ; caule gracili stricto ; 
foliis anguste linearibus sursum filiformi-attenuatis integerrimis vel summis cum bracteis viridi- 
bus trifidis, lobis attenuatis; spica angusta; calyce corolla tertia parte breviore postice fisso, 
dentibus linearibus obtusis tubo dimidio brevioribus; corolle labio inferiore vix trisaccato, 
appendiculis oblongis obtusis ventriculo brevioribus galeam rectam truncatam subequantibus ; 
antheris bilocularibus. Corte Madera; April 16. A span high. Corolla narrow, 7 lines long, 
puberulent, white or cream-color, with the slightly ventricose lower lip spotted with purple.
