Among the last seeds sent from California liy Mr. Douglas, 

 were some of this plant, which forms an interesting addition 

 to the genus Hosackia. It is much larger than any other 

 known species, forming a stout bush about three feet high, 

 and multiplying itself readily by its creeping roots. Altliough 

 its flowers are unattractive, it forms a good shrubbery plant, 

 where it is desirable to form the appearance of under- 

 growth quickly — for it resembles a shrub during the sum- 

 mer, and it spreads so fast as soon to extend far beyond its 

 original station. It flowers in June, and produces an abun- 

 dance of its seeds in August. 



It is nearly allied to H. crassifolia, which is distinguished 

 by its scarions stipules, 4- or 5-paired leaves, with more ob- 

 tuse leaflets, and few-flowered umbels. 



I remarked among the seeds I examined, two whose 

 embryos had three cot^dedons, an unusual occurrence, the 

 more interesting as taking place in the embryo of a species 

 whose leaves are unequally pinnated, and indicating a kind 

 of foreshadowing in the rudimentary plant of the plan of 

 organization in the perfect plant.
