* Perennis, caulibus rigidis e basi suffruticosa : anthers lineari- 

 sagittatae. 



32. G. densifolia, Benth. G. (olim Hugelia) densifolia & elon- 

 gata, Benth. 1. c. — No other specimens of G. densifolia have been 

 found exactly answering to those of Douglas ; these have 5-7 (accord- 

 ing to Bentham about 10) ovules in each cell, those of G. elongata 

 only two or three. Specimens collected by Xantus at Fort Tejon, and 

 by Dr. Cooper on the Mohave, are as near as may be intermediate. 



* * Annua?, graciliores, demnm paniculato-ramosae, foliis segmen- 

 tisve saepius paucis filiformibus. 



33. G. virgata, Steud., Benth. I. c. Priraum stricticaulis, sim- 

 plex ; antheris (in sicco) linearibus sagittatis lineam longis. — Hugelia 

 virgata, Benth., Hook. Ic. t. 200 (anthers figured too short). The 

 ordinary form has most of the cauline leaves entire, and the upper of 

 few divisions. Lobes of the corolla three lines long. 



Var. floribunda : corymboso-ramosa ; capitulis majoribus multi- 

 floriti ; foliis magis dissectis. — California, Fitch, Wallace, Brewer. 

 Ovules vary from two to five in each cell. 



34. G. floccosa. Gracilior, spithamaea, demum diffusa paniculata" ; 

 antheris lineari-oblongis vix semilineam excedentibus ; floribus minoiv- 

 bus; ovarii loculis nunc uni- nunc bi- rarius 3 - 4-ovulatis. — Hugelia 

 lutea, Benth. in Bot. Beg. Gilia (Pseudocollomia, Benth.) lutescens, 

 Steud., Benth. in DC. — California to Arizona, interior of Oregon, and 

 Utah. Flowers blue or pale purple, becoming white only in age, and 

 though appearing yellowish in original dried specimens of Douglas, 

 probably never yellow. Hence a new specific name is required. 

 Nuttall has an unpublished Hugelia floccosa in his herbarium, but 

 with no flowers developed ; and, as it is either this or the next, the 

 name may be applied to the present species. 



35. G. filifolia, Nutt. Gamb. p. 156. Gracilis, spithamaea et 

 ultra, rigidula ; foliis plerisque tripartitis ; antheris ovalibus minimis ; 

 corollas tubo parum exserto ; ovarii loculis saepius 4 - 6-ovulatis. — 

 Santa Barbara and San Isabel, California, Nuttall, Thurber ; and Fort 

 Mohave, Cooper. 



Var. diffusa : laxa, nunc ramosissima. — Fort Mohave and Nevada 

 to New Mexico and the borders of Texas. Lobes of the pale purple 

 or blue corolla only one or two lines long : anthers only a quarter or 

 one third of a line in length. Forms of this approach the preceding 

 too nearly.
