* Erect, 3 to 5 feet high, destitute of prehensile branchlets: flowers crowded in a spike 



or raceme, mostly rose-colored. 



1. A. virga, Gray, 1. c. Glabrous : stem strict and simple (its base unknown) : 

 upper leaves linear, gradually diminished upwards into subulate or setaceous bracts 

 of the long and naked spike-like raceme : flowers mostly secund, soon horizontal : 

 corolla with narrow tube (half an inch long) fully twice the length of the lips : 

 dilated tip of the longer filaments broader than the anther. 



Known only in a collection made by the late Thomas Bridges, the station unknown. 



2. A. glandulosum, Lindl. A tall and rather coarse herb, very glandular- 

 pubescent and viscid throughout, branching and leafy : leaves lanceolate, mostly 

 sessile, gradually passing into bracts of the dense spike or raceme : sepals unequal : 

 corolla (over half an inch long) pink with a yellowish palate : capsule tipped with 

 a long persistent style. Bot. Keg. t. 1893. 



Gravelly beds of streams, from Santa Cruz southwards. 



* * Erect, a span or two high, destitute of prehensile or tortile branchlets : flowers 

 small, yellowish or dull-colored, sessile or nearly so in tlie axils of the almost uni- 

 form leaves, beginning nearly at the base of the stem : sepals equal, linear : whole 

 style indurated and persistent. 



3. A. cornutum, Benth. Villous and viscid, simply branched : leaves linear- 

 oblong or lanceolate (an inch long), the lower tapering into a short petiole : fila- 

 ments all dilated at tip : style rather longer than the capsule : seeds echinate and 

 pitted. PI. Hartw. 328. 



Valley of the Sacramento, Hartweg. No one else has yet found it. Corolla less than half an

4. A. leptaleum, Gray, 1. c. Slender, viscid -pubescent, mostly simple-stemmed : 

 lower leaves almost linear (less than an inch long) ; the upper and smaller spatulate- 

 oblong : shorter filaments hardly at all dilated : style rather shorter than the capsule : 

 seeds rugose-pitted. A. cornutum, Durand, Pacif. E. Rep. v. t. 10, not Benth. 



Banks of streams, Mariposa to Kern counties, Bolander, &c. Corolla a quarter of an inch long. 



* * * Erect or spreading, branching, slender, producing filiform and at length tortile 

 axillary branchlets, by which the plant is disposed to climb : calyx unequal: corolla 

 (small) short, both lips spreading, the lower larger and as long as the tube. 



-t- Flowers in a naked spike or dense raceme : bracts minute. 



5. A. Coulterianum, Benth. Stem weak, 2 to 4 feet high, gaining support 

 by its numerous filiform tortile branchlets acting as tendrils, glabrous below, as are 

 the linear or narrow-oblong and distant leaves : spike villous-pubescent and viscid, 

 virgate, 2 to 10 inches long : pedicels usually shorter than the linear or lanceolate 

 obtuse sepals, which are shorter than the ovate-oblong capsule : style short. 

 DC. Prodr. x. 592. 



Santa Barbara Co. to San Diego, Coulter, Wallace, Cleveland, &c. Corolla either violet-purple

 times from the lower part of it. 



-t- -f- Flowers (purple or blue, rarely white) scattered along the slender diffuse branches, 

 in the axils of leaves or leaf-like bracts, some of them often accompanied by tortile 

 prehensile branchlets : upper sepal conspicuously larger than the others : haves 

 short, from linear to ovate. 



++ Peduncles mostly shorter than the calyx, sometimes hardly any : tube of the corolla
