antico asstivatione exteriore. Folia floralia et bracteae apice (C. 

 laxijloro excepto) saepissime truncatte retusae vel subtridentatis callo 

 glaiiduteformi pi. m. manifesto instructae. 



* Calyx phyllo antico sub-5-nervi, postico subscarioso binervi bificlo. 

 Stamina 2 : filamenta fere glabra : antheras biloculares. Folia floralia 

 tritida vel subpinnatifida. 



CoRDYLANTHUS CAPiTATUS, Nutt. Appears to have been found 

 only by Nuttall. I possess a short flowering branch, on which I can 

 confirm the characters assigned by Bentham, and add that the posterior 

 division of the calyx is only 2-nerved (the nerves distant Tind running 

 to the apex of the lobes), as in no other known species. Appai'ently 

 the inflorescence is hardly as much capitate as in the next. 



* * Calyx phyllis 5 - 6-nervibus, postico etiam integerrimo vel emar- 

 ginato. Stamina 4 : filamenta pi. m. villosa : anthers omnes bilocu- 

 lares. Folia angusto-linearia seu filiformia, 



-i- Superiora et floralia 3 - 5-fida, cum ramis minutim scabro- vel 

 subglanduloso-puberula. 



COKDTLANTHUS FiLiFOLius, Nutt., Benth. (Adetiosteffia rigida, . 

 Benth. olim.) Folia caulina inferiora integerrima ; floralia parce 

 hispida prtesertim ad margines, basi subcuneata, segmentis apice pi. m, 

 dilatatis. Floras capitato-conferti. Calycis phylla oblonga obtusa. — 

 I have no Nuttallian specimen of this, but one from Douglas and from 

 other collections. I possess a mere fragment of C ramosus, Nutt., 

 which I suppose to be a slender and somewhat canescent form of 

 the present species. 



CoRDTLANTHDS Wrightii, Gray in Bot. Mex. Bound, p. 120. 

 Folia omnia quae exstant 3 - 5-partita, filiformia ; floralia conformia, 

 nee hispida. Flores pauci ad apice ramorum, poUicares: calycis phylla 

 lanceolata. — Dr. Parry has recently collected this in New Mexico ; 

 the flowers evidently purple or purplish. 



-i--i- Folia fere semper etiam floralia integerrima. Flores subpani- 

 culati. 



CoRDYLANTHUS PiLOSUS : elatus (3 - 4-pedalis), pilis mollibus pa- 

 tentibus ut videtur subviscidis cinereus ; foliis linearibus, superioribus 

 plerumque apice truncato-emarginatis vel dilatato-trilobulatis ; floribus 

 confertis demum furcato-paniculatis ; calycis phyllis lanceolato-oblongis. 

 — Dry soil, near San Jose, Brewer : Oakland hills, Bolander : Upper 

 Sacramento, Dr. Newberry. — Var. Bolanderi : inferne viscoso- 

 glandulosus, parce seu vix pilosus ; floribus laxius paniculatis ; fohis
