BOTANY. 81 
November 18, (in fruit.) K. viridis is hardly a distinct species, and the genus itself might be 
reduced to a section of Astragalus. 
LUPINUS SPARSIFLORUS, Benth. Pl. Hartw., p. 303. Gravelly hills, on the Colorado, western 
New Mexico, February 26. A form with less hirsute leaves. Also a larger form, February 17. 
Lupinus NANUS, Dougl.; Benth. in Hort. Trans., p. 459, t. 14, f. 2. Corte Madera, California; 
April 12-15. Some of the specimens are a foot or more in height. Those with broader 
eaflets accord with “L. manus var. latifolius,” Benth. in Herb. Coulter. The flowers are 
sometimes white. 
LUPINUS DENSIFLORUS, Benth. in Hort. Trans. n. ser. 1, p. 409. L. Menziesii, Agardh, Syn. 
Lup., p. 2. Woods and shady places, Knight's Ferry, on the Stanislaus river; May 7. Mr. Ben- 
tham (in Pl. Hartweg p. 303) points out that Agardh has founded his L. Menziesii upon the 
Douglasian plant, which he had described as L. densiflorus. All confusion about the synonymy 
may be avoided, however, for the two species, L. densiflorus and L. Menziesii, 4g., cannot be 
kept distinct. Both have white flowers, (Agardh wrongly attributes yellow corollas to his L. 
Menziesii, but his guess from the appearance in dried specimens is not correct in this, nor in 
some other instances ;) and the longer bracts and very villous calyxes of Agardh's L. densiflorus 
are evidently not available for a specific distinction. Dr. Bigelow's specimens, however, corre- 
sponds in this respect with L. Menziesii. 
LUPINUS BICOLOR, Lindl. Bot. Reg. t. 1109 ; Agardh, l. c. p. 14. L. micranthus, Dougl. in Bot. 
Reg. t. 1251; Torr. & Gray, l. c. Wet places, near San Francisco, April 8. Plains, near 
San Gabriel ; March 23. 
LUPINUS LEPTOPHYLLUS, Benth. in Hort. Trans. l. c. t. 14, f. 2; Torr. € Gray,l. c. Hills and 
rocky places, Knight's Ferry, Stanislaus river; May 7. 
LUPINUS LATIFOLIUS, Agardh, l. c. L. cytisoides, Agardh, l. c.; Torr. de Gray, .ا‎ c. Corte 
Madera, April 12; and hill-sides, Martinez, California; April 23. L. cytisoides was supposed by 
Agardh to have yellow flowers, but he saw only dried specimens, and was very probably mistaken. 
LUPINUS RIVULARIS, Lindl. Bot. Heg. t. 1595 ; Torr. € Gray, Fl. 1, p. SY. Plains, near San 
Gabriel, March 23. Rather more silky than the ordinary state of the plant. Except in the 
entire calyx, it scarcely differs from L. Douglasii. 
LUPINUS LAXIFLORUS, Dougl. in Bot. Reg. t. 1140; Torr. & Gray, l.c. Hill-sides, Stanislaus 
river, near Carson's, May 14. We are doubtful about our determination of this plant, as the 
calyx is not very decidedly gibbous. 
LUPINUS DECUMBENS, Torr. var. ARGOPHYLLUS, Gray, Pl. Fendl. p. 37. Gravelly hills, near 
San Antonita, New Mexico; October. L. laxiflorus, Dougl., probably passes into this species. 
LUPINUS ALBIFRONS, Benth. in Hort. Trans. 1, c. p. 410; Lindl. Bot. Reg. t. 1642; Torr. d 
Gray, l. c. Sand hills, on the sea-shore ; Punta de los Reyes; and near San Francisco. April 
3-17. A fine shrubby species. 
Lupinus onNATUS, Dougl. in Bot. Reg. t. 1216; Agardh, l. c. p. 28; Torr. d Gray, Fl. 1, p. 
378. Butte mountains, California; May 25. 
LUPINUS MACORCARPUS, Hook. & Arn. Bot. Beech., p. 138. On sand hills, near the sea; Punta 
de los Reyes, California; April 17. This species was discovered many years ago by Menzies, and 
seems not to have been found again till Dr. Bigelow collected it in Whipple's expedition. It 
resembles L. arboreus (which Dr. Parry obtained near San Diego) in its shrubby stem and 
large yellow flowers, but that species is minutely pubescent; this is very hirsute, and the leaves 
are silky underneath. The petioles of both are shorter than the leaflets, and in our speci- 
mens of L. macrocarpus the flowers are decidedly verticillate. We have not seen the pods. 
'THERMOPSIS MACROPHYLLA, Hook. de Arn. Bot. Beech., p. 329; Torr. € Gray, Fl. 1, p. 388. 
L. montana, Nutt. in Torr. € Gray, Fl. 1. c. Corte Madera, April 15.  Leaflets often 
broadly obovate. Nuttall's T. montana can hardly be considered as more than a smoother 
form of this plant, with usually narrower leaves. We have specimens that are intermediate 
between the two.
