corolla one and one-third inches long. This has been con- 

 founded with P. Palmeri of the interior, but is very different- 

 1 he flowers in the bud closely resemble those of Scrophulana. 

 Keane, California, May 21, 1903. 



Pentstemon pseudospectabilis n. sp. 



Lower leaves oblong-IanceoIate, about 3 inches long, 

 pectinately toothed; stem leaves mostly triangular-lanceolate 

 and very acute, completely connate, mostly entire, the upper- 

 most leaves the narrowest; cymes nearly always sessile, with 

 pedicels 6 lines to 1 inch long and erect; otherwise as in P. 

 spectabilis. This is easily separable from that species by the 

 sessile cymes, narrow leaves narrowest (not widest) above on 

 the stems and by the strict and very narrow thyrsus. It has 

 the same red-purple flowers and nearly glabrous sterile fila- 

 ment and suffrutescent base. Chimihuevis Mts., northwestern 

 Arizona, at 3000 feet altitude, April 23, 1903. 

 Pentstemon flavifliorus n. sp. 



Closely allied to P. strictus, but corolla less ampliate, the 

 lobes shorter, and anthers different ; tall, strict and erect, sev- 

 eral feet high, paniculately branched above with narrow 

 thyrsus on each stem, apparently glabrous throughout with 

 thick and rigid leaves; the upper leaves only seen, linear- 

 lanceolate, 2-4 inches long, acute, entire, sessile, with cordate 

 base; bracteal leaves reduced to ovate or subulate and ver>' 

 .^mall bracts; peduncles mostly 2-flowered and 2-4 lines long 

 (sometimes 9 lines long and proliferous with the ultimate pe- 

 duncles like the normal ones) ; pedicels slender, about 6 lines 

 long; sepals oval, ly^-Z lines long, with narrow hyaline mar- 

 rins. abruptly acute or with a short acumination, about one- 

 third the ovate pod when mature; corolla yellow, IYa-^Y^ 

 inches long, proper tube 1 Une wide and about double the 

 calyx in length, then rather abruptly enlarged to the throat, 

 which is 5 lines wide and with short and broad lobes, obscurely 

 bilabiate, short-bearded within; anthers exserted, backs of 

 cells forming a straight line as in P. barbatus and half-oval, 

 distmct, Yi hne long, glabrous, split nearly to the top; sterile 

 filament glabrous. 



Pentstemon pulchellus is a reduced form of P. caeruleo- 

 purpureus. 



Gerardia paniculata n. sp. 



Annual allied to G. aspera very closely; scabrous, stems 

 several, paniculately branched above; leaves linear-subulate.
