LuPiNUS MiCRANTHUS Dougl.; Lindl Bot. Reg. 15: pi. 12^1. 

 1829. 



"If this is not to be compared in point of beauty with such 

 fine species as L. perennis, ornatus and others, which have been 

 already figured in this work from Mr. Douglas's collection, it is 

 nevertheless interesting as an addition to the number of species 

 of annual Lupines. 



"According to Mr. Douglas, this has much affinity with 

 Lupinus bicolor, published at fol. 1109 of this work, from which 

 it differs in being more slender, and in flowering from four to 

 six weeks earlier. It is more particularly to be distinguished 

 from that species by the shortness of its alae, its nearly sessile 

 flowers, fleshy leaves, granulated roots, larger pods, and the col- 

 our and size of the seeds. 



"Mr. Douglas found it abundantly upon the gravelly banks 

 of the southern tributaries of the Columbia, and in barren 

 ground in the interior of California. 



"A hardy annual, flowering from May to July. Our draw- 

 ing was made in the Garden of the Horticultural Society in 

 1828. 



" 'Annual. Root fibrous, with warty, fleshy tubercles. 

 Stem erect, branching, about a foot high, with short white 

 downy hairs. Leaves digitate, with subulate, dark stipules. 

 Leaflets 5-7, linear-spatulate, smooth above, ciliate with minute, 

 short, fine hairs below, thick and fleshy, three-fourths of an inch 

 long. Flowers partly whorled, few, sessile. Bracteae subulate 

 pilose, darker than the leaves. Calyx silky, upper lip bifid, 

 under entire. Vexillum ovate, blue, white in the centre, with 

 two or four parallel black dots. Alae oblong, same length as 

 the vexillum; keel falcate, acute: Legumen linear-oblong, with 

 transverse furrows, 5 or 6-seeded. Seeds large, brownish gray, 

 mottled.' — Douglas. J. L." 



The above is the original description of L. micranthus., ex- 

 cept that the Latin description, immediately preceding the first 

 paragraph quoted is omitted as unnecessary, the English one 

 being a translation of it.
