SERICOGRAPHIS CALIFORNICA (Gray MSS.): “foliis parvis ovalibus ovatis vel subcordatis, utrinque 
cum ramis teretibus pube molli brevissima tomentulosis; racemis brevibus laxifloris; floribus 
aut breviter aut longiuscule pedicellatis; bracteolis Наваан calyce brevioribus; corolla 
rubella longe tubulosa, labiis truncatis, superiore emarginato, inferiore 3-dentato; antherarum 
loculis subzequalibus sejunctis, inferiore basi calcare obtuso brevi incurvo auctis, Beloperone 
Californica ; Benth. Bot. Voy. Sulph. р. 38? Jacobina Californica, Nees in DO. Prodr. 11, p. 
729. Southern part of California; Frémont. Vallecita, California; Thurber. Although not 
agreeing in every respect with the description, these incomplete specimens probably belong to 
Bentham's Beloperone Californica, which Nees has not inaptly referred to his genus Jacobinia ; 
but it surely belongs to Sericographis. It has the hairy lines, answering to the bases of the 
suppressed stamens, well-marked. In one blossom there were three perfect stamens. "The upper 
lip of the corolla neatly shows the two long membranous lamelle which connive and form a 
long channel containing in the bud the upper part of the style; a character which Cirsted has 
added to the description of this and some related genera." A. Gray. 
ADHATODA? LONGIFLORA (n.sp.): caule erecto minute pubescente suffruticoso; foliis lanceolato. 
oblongis glabris sursum angustatis acutiusculis basi in petiolum attenuatis floribus fasciculatis 
axillaribus.terminalibusque sessilibus, tubo corolle elongato gracili. Road between Zuii and 
Alta Sonora, September; Schott. Plant apparently about a foot high; branches erect and 
slender. Leaves (including the petiole) 13-2 inches long and 3-5 lines wide, entire, nearly 
smooth. Flowers fascicled in the uppermost axils. Calyx a little shorter than the lanceolate 
bracts and longer than the subulate bracteoles, the segments subulate. Corolla white?; border 
4-lobed, the three lower segments oblong, the upper segments bifid at the summit. Stamens 2, 
exserted ; anther-cells separate, one placed above the other, obtuse at the summit, acute at the 
base. Ovary 4-ovuled. This seems to be distinct from any species of the genus described by 
Nees. 
DICLIPTERA RESUPINATA, Juss. in Ann. du Mus. 9, p. 268 fide Nees, l. c., p. 474? D. thlaspoides, 
Nees, l.c. Santa Magdalena and Bacuachi, Sonora, September, October ; Thurber, Schott. (No. 
1465, Wright.) Our plant is a perennial, and some of the specimens seem to be even suffruticose, 
but D. resupinata and thlaspoides are said to be annuals. The length of the peduncle is variable; 
in Schott’s and Wright's specimens it is as long as the lateral divisions, but in T'hurber's 
they are sometimes very short, and the middle division much elongated. The heads, also, 
although mostly 1-flowered, are sometimes 2-flowered. The bracts are mostly broadly cordate, 
but in Mr. Thurber's specimens from Bacuachi they are ovate and obovate.
