On the Mohave slope of the San Bernardino Mountains, Parry, Dec. 1875, in fruit only. 

 Leaves on new shoots 2 or 3 inches long and only 2 or 3 lines wide. Cymes apparently pedun- 

 culate. Capsule and calyx only 2 lines or so in length. Stem IVigandia-like, over half an inch in 

 diameter at base, decidedly woody, but with a large pith.

8. A. Nuttallianum, var. effusum, Gray. Climbing over bushes, 5 feet high : 

 flowering branches paniculate : pedicels all filiform and longer than the flowers: ribs 

 of the seeds less wing-like : calyx-lobes rather less unequal. 



Jamuel Valley, southeast of San Diego, Dr. Palmer.

14 a . P. Fremonti, Torr. & Gray. A span or more high, pruinose-puberulent 

 or below glabrous : leaves lanceolate or oblong-lanceolate, and the lowest spatulate 

 or oval, an inch or two long : flowers racemose-thyrsoid, rather crowded and numer- 

 ous : pedicels and mostly the peduncles short and glandular-pubescent : corolla pur- 

 ple or whitish, half an inch or more in length, tubular-funnelform : anthers not 

 opening widely : sterile filament dilated and bearded at the tip. Proc. Am. Acad. 

 vi. 60; Watson, Eot. King. Exp. 218. 



Sierra Nevada, on a high mountain near Donner Pass ( Torrey) ; Utah, Fremont. A smoother 

 and taller variety (Parryi), Nevada, Watson, Wheeler, &c. 



After no. 17, add a fifth subdivision, as follows : 



-n- *+ -M- -n- ++ Corolla scarlet, tubular ; its upper lip erect and ^-toothed ; the lower 



reflexed and ^-parted. 



17 a . P. barbatus, Nutt., var. labrosus, Gray. Entirely glabrous, somewhat 

 glaucous : stems virgate, 2 feet high or more : lowest leaves oblanceolate ; the upper 

 narrowly linear : panicle slender and raceme-like : sepals ovate, short : corolla an 

 inch and a half long ; its lips half an inch or more ; the upper oblong and concave, 

 barely 2-lobed at the tip ; the lower 3-parted into linear divisions ; these and the 

 throat glabrous, as also the stamens and style : anther-cells divaricate, never spread- 

 ing open, the inner portion of the line of dehiscence remaining cl'osed. 



On Mount Pinos, south of Tejon, at 7,000 feet, Rothrock in Wheeler's Expcd., 1875. A remark- 

 able form, seemingly, of P. barbatus, agreeing with the var. Torreyi of New Mexico and Colorado 

 in the want of beard ; but the lobes of the lower lip remarkably long and narrow. The tube of 

 the corolla appears to have been yellowish, the lips scarlet.

Chloropyron palustre, Behr in Proc. Calif. Acad. i. 62, 66, is some one of the species of this 

 genus, with reduced anther-cells ; perhaps 0. faucibarbatus or 0. floribundus.

3. C. filifolius, Nutt. The ripe seeds are ovate or oval ; the coat close, and in 

 the dry state lineate-reticulated under a lens with innumerable slender wavy lines 

 or wrinkles : embryo little shorter than the nucleus, the cotyledons orbicular. The 

 ovules are slender, tapering to the apex, which is coiled into a helix. 



Yar. brevibracteatus, Gray. Tall and stouter, glabrous up to the floral leaves ; 

 these hirsute-ciliate and all shorter than the flowers, more dilated, and not gland- 

 tipped : cauline leaves not seen. 



Near Soda Spring on Kern River, at 8,500 feet, Rothrock in Wheeler's Exped., 1875. A rather 

 smooth form collected by D. Cleveland near San Diego approaches this.
