412 SUPPLEMENT. 



Common in S. California and east to Nevada : has mostly been referred to G. inconspicua, 

 var. sinuata, p. 148. 



G. tenuiflora, BENTII., p. 147. Radical leaves often cottony-tomentose when young, soon 

 glabrate : calyx at most 2 lines long : corolla from half-inch to inch and a quarter long 

 (including the lobes) ; the slender tube dilated into the somewhat narrowly funnelform 

 throat. S. California to S. Utah. 



G. inconspicua, DOUGL., p. 148. The panicles or flowering branches when well developed 

 are rather rigidly erect, at least not effuse ; the lateral peduncles short and erect, at least in 

 fruit. The figures of Smith and of Hooker (from weak plants raised in England, and from 

 which Beutham has mainly drawn the character) do not very well represent the species, 

 although the whole tube of the small corolla is often thus included. Yet it is very commonly 

 more exserted (as in var. sinuata), even before the fructified ovary enlarges, but always sal- 

 verform, having a small and narrow throat, and limb only 2 to 4 lines in diameter. The 

 effusely-flowered plants with ampliate throat, which were included in var. slnnatn, are now 

 taken for a small-flowered variety of G. latiflora. Apparently there are connecting forms 

 between all these species.

3. LQESfiLiIA, L. Flowers involucrate or involucellate ; both bracts and 

 calyx wholly or mainly scarious. Corolla funnelform, either regular or one or 

 two sinuses deeper. Seeds winged or margined, the surface becoming mucilagi- 

 nous when wetted. Suffruticose, rarely annual, with spinulose-toothed leaves. 



L. glandulosa, DON. Low, merely suffrutescent, ronghish-pubescent with short and partly 

 gland-tipped hairs : leaves mainly alternate, short-petioled or subsessile, lanceolate or nar- 

 rowly oblong, those next the-l-2-flowered clusters similar but small, few-toothed, not scarious 

 nor reticulated, nearly enclosing the involucre of wholly scarious oblong-lanceolate almost 

 entire bracts : corolla violet or bluish. 6 or 8 lines long : filaments more or less declined- 

 iucurved: seeds broadly winged. Syst. iv. 248; Benth. in DC. Prodr. ix. 319, in part (i. e. 

 Hoitzia conylomerata, HBK., H. capitata, Willd., & //. nepetcefolia, Cham.). Hoitzia ylan- 

 dulosa, Cav. Ic. Ear. iv. 45, t. 367. //. Cervantesii, HBK., Nov. Gen. & Spec. iii. 164. //. 

 spicata, Willd. ex Rcem. & Schult. Syst. iv. 370. Santa Rita Mountains, S. Arizona, 

 Pringle. (Mex.) 



5. (to be 4.) POLEM6NIUM, TOUEN. Flowers naked. Calyx herba- 

 ceous throughout, soft, usually accrescent. Corolla from rotate to fuunelforin. 

 Filaments pilose-bearded at base. Leaves simply pinnate, muticous. 



P. cseruleum, L. p. 151, only recently known at one or two stations in the Atlantic States, 

 has now been detected also at Bethlehem, New Hampshire, by F. 8. Beane, and on the moun- 

 tains in Garrett Co., Maryland, by J. Donnell Smith. 



P. flavum, GREENE. Like P. foliosissimum, but with flowers somewhat more paniculate and 

 larger : corolla fully as large as in P. canileum, " yellow with tawny red outside," with broadly 

 obconical throat and ovate acuminate lobes ! Bot. Gazette, vi. 217. Highest slopes of the 

 Pinos Altos Mountains, New Mexico, Greene. 



P. pectmatum, GREENE. Glabrous and glamlloss up to the minutely glandular and pu- 

 bescent inflorescence : leaflets very narrowly linear, hardly wider than the rhachis : corolla 

 probably white : otherwise not unlike narrow-leaved P. foliosissimum, of which it may be an 

 extreme variety. Bull. Calif. Acad. i. 10. Eastern part of Washington Terr., E. W. 

 I/ili/nrd, fide Greene. 



P. carneum, GRAY, p. 151. Extends to the southwestern part of Oregon, where it was 

 collected at Chetco by Iloirell. 



Var. luteum. Corolla yellow, the lobes (as in the species) broadly obovate, with 

 rounded or refuse apex. Cascade Mountains, Oregon, Howell, 1885. 



P. foliosissimum, GRAY, p. 151. To this probably belongs P. Mexicanum, Nutt. Jour. 

 Acad. Philad. vii. 41, from the northern Rocky Mountains.
