OF ARTS AND SCIENCES : OCTOBER 14, 1862. 57 



^3. DoDGLASii. {P. Douglasii, Hook,, spec, fructif. P. crassifo- 

 lius, Lindl. Bot. Reg. 24, t. 16, florif.) Folia integerrinia, s^pius 

 obovato-lanceolata : calycis segmenta ex ovato lanceolato-acuminata. 



y. ScouLERi. {P. Scouleri, Dougl., Lindl. Bot. Reg. t. 1277.) 

 Folia obovato-lanceolata vel oblanceolata, plerisque argute serrata: 

 calycis segmenta ex lanceolate attenuato-acuminata. 



8. Newberryi. (P. Newberryi, Gray, in Pacif. R. R. Exped. 6, 

 p. 82, t. 14.) Folia var. a. cum calycis fere var. y. : corolla rubro- 

 purpurea? — Dr. Newberry noted the corolla as "crimson." If really 

 of the red series, I was justified in characterizing it as a new species ; 

 but I much suspect that the color is purple. The corolla is that of 

 P. Menziesii, somewhat reduced in size. 



§ 2. (Fruticosi.) Frutices vel suffrutices ramosi (3 - 6-pedales), 

 ramulis floridis s£epe hei-baceis, foliis coriaceis parvis parvulisve 

 subpetiolatis. Inflorescentia paniculata pluriflora. Corolla bila- 

 biata, labio superiore pi. m. arcuato-incurvo, inferiore deflexo 

 vel patente. Antherae glabrae, usque ad apicem dehiscentes, 

 eiFoetae explanatse. Californici. 



* Brevijiori ; corolla profunde bilabiata ringente flavescente, labiis 

 tubo Eequilongis vel sublongioribus. Folia basi attenuata. 



2. P. MiCROPHYLLDS, Gray, in Pacif R. R. Exped. 4, p. 119. 

 Cinereo-puberula ; foliis ramealibus primariis deciduis vel ad squamas 

 minimas reductis, fasciculorura lineas 2 tantum longis obovatis retusis 

 integerrimis ; sepalis lanceolato-ovatis acutis. — Williams's Fork of the 

 Colorado, between New Mexico and California. Corolla and stamens 

 unknown. Probably allied to the next. A style that remains indi- 

 cates a rather short corolla. 



3. P. ANTiRRHiNOiDES, Benth. Subcinercus, fere glaber, ramo 

 sissiraus ; foliis spathulato-lanceolatis oblongisve integerrimis ; pedun- 

 culis diphyllis stepius unifloris ; sepalis ovato-rotundis ; corolla lutea 

 nuda, labiis amplis ; filamento sterili superne dense barbato. 



4. P. BREVIFLORUS, Benth. Floribus exceptis glaberrimus ; foliis 

 lineari- seu oblongo-lanceolatis argute serrulatis ; pedunculis plurifloris ; 

 sepalis ex ovato acuminatis aut glabris aut glanduloso-hirsutis; corolla 

 extus glanduloso-bai'bata flavescente intus purpureo tincta, tubo per- 

 brevi; filamento sterili glabro. — The beard, generally so conspicuous 

 on the summit of the unexjianded corolla, is sometimes almost wholly 



wanting.
