BOTAOT. 
deeply 5-cleft or 5-parted, very hirsute, lobes oblong- or ovate-lanceolate, 
usually acute ; corolla-tube short, equaling or but little exceeding the calyx, 
and rarely as long as the deep-l}luc limb ; anthers inserted near the base of 
the tube, and included within it ; style very short. — This was collected by 
Fre'mont in 1844 on Spanish Fork in the Wahsatch ; by Stansbury, also in 
the Wahsatch ; by Burke in Southern Idaho, and by Hall & Harbour (443) 
in Colorado. It is a pretty species, of pecuhar 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 tlie filaments variously inserted upon the tube. — The numerous 
specimens arc so exceedingly variable in habit, foliage, position of the sta- 
mens and other characteristics of the Hower, that it becomes unavoidable to 
include in this species both A. Mexicana^ IMart. & Gal., and A. intermedia, 
and perhaps also A, qjectahilis, Fisch. & Mey., and the Chilian species A. 
angiist'ifolla, Lehm., as has already been suggested by both Dr. Torrey and 
Dr. Gray. From AVashington Territory to Sonora, Arizona and Utah. Fre- 
cpient 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, Leiim. Calyx r)-iiarted. Corolla salver-form, plicate in fPstivation but witliovit 
sciles, the tube nanow and usually nmcli lorifrer than the lobes. Stamens vrith very short filiform fila- 
ments. Sfyle elon-atrd, intluded. Xutlets 4, narrow-ovoid, more or less triangular, attached to the 
siylr to aix.v.. the l^iddh^ S.'imIs cxalbuiuinous, the radicle superior, and the obovate cotyledons 
r2-paitcd.— Annual, hisiiid. witli alti inate entire leaves and racemose spicate ebracteate yellow flowers. 
*=PIPTOCAL^ X. Torn;. Calyx 5-cleft, circumscissile above the base, deciduous. Corolla salver- 
form, the throat with fulds or oihl.e but without scales. Stamens included. Nutlets 4, triangular- 
ovate, attenuated above, jrlabmus and shining, attached to the axis the whole length.— Annual, dwarf, 
with lu.ear alleniaf ka\ « s, the minute ilowers in terminal leafy scorpioid racemes.
