BOTAJST. 



deeply 5-cleft or 6-parted, very hirsute, lobes oblong- or ovate-lanceolate, 

 usually acute ; corolla-tube sbort, equaling or but little exceeding tbe calyx, 

 and rarely as long as the deep-blue limb ; anthers inserted near the base ol 

 the tube, and included within it ; style very short.-This was collected by 

 Frt^mont in 1844 on Spanish Fork in the Wahsatch; by Stansbury, also m 

 the Wahsatch ; by Burke in Southern Idaho, and by Hall & Harbour (443) 

 in Colorado. It is a pretty species, of peculiar habit, growing on rather dry 

 slopes; placed by Dr. Gray under M. alpina, but the differences are so con- 

 stant and obvious that it seems to deserve higher rank. In the Wahsatch 

 and Uintas; 5-7,000 feet altitude; May, July. Plate XXIII. Fig. 1. 

 Flowering stem; natural size. Fig. 2. Flower, laid open; enlarged six 



diameters. (845.) 



Amsinckia^ lycopsoides, Lehm. DC. Prodr. 10. 117. Very hirsute, 

 erect, 2'-3° high, simple or branched ; leaves ovate-, oblong- or linear-lance- 

 olate, acute or obtuse, becoming white-papillose-scabrous with age ; corolla 

 2-5" in length, the deep-orange limb rather narrow, the throat pilose or glab- 

 rous, and the filaments variously inserted upon the tube.— The numerous 

 specimens are so exceedingly variable in habit, foliage, position of the sta- 

 mens and other characteristics of the flower, that it becomes unavoidable to 

 include in this species both A. Mexicana, Mart. & Gral., and A. intermedia, 

 and perhaps also A. spectaUUs, Fisch. & Mey., and the Chilian species A. 

 angustifolia, Lehm., as has already been suggested by both Dr. Torrey and 

 Dr. Gray. From Washington Territory to Sonora, Arizona and Utah. Fre- 

 quent on dry slopes from the Washoe Mountains to the Wahsatch ; 4-6,500 

 feet altitude ; April-July. (846.) 



PiPTOCALYX® ciRCUMSCissus, Torr. (Lithospermum, H. & A. DC. Prodr. 

 10. 84.) Very hispid with white rigid hairs; stems numerous, branched, 

 ascending, 1-2' high ; leaves 2-4" long ; the deciduous portion of the 5-angled 

 calyx about 1" long ; corolla very small, white, scarcely exceeding the calyx ; 



'AMSINCKIA, Lehm. Calyx 5-parted. Corolla salver-form, plicate in asatiTation but without 

 scales, the tube narrow and usually much longer than the lobes. Stamens with very short filiform fila- 

 ments. Style elongated, included. Nutlets 4, narrow-ovoid, more or less triangular, attached to the 

 style to above the middle. Seeds exalbuminous, the radicle superior, and the obovate cotyledons 

 2-parted. — Annual, hispid, with alternate entire leaves and racemose spicate ebracteate yellow flowers. 



ispiPTOCALYX, ToEB. Calyx 5-cleft, circumscissile above the base, deciduous. Corolla salver- 

 form, the throat with 5 folds or gibbie but without scales. Stamens included. Nutlets 4, triangular- 

 ovate, attenuated above, glabrous and shining, attached to the axis the whole length. — Annual, dwarf, 

 with linear alternate leaves, the minute flowers in terminal leafy scorpioid racemes.
