between Fort Vancouver and the grand rapids of the Columbia. It is 

 quite hardy, and easily increased by seeds. Our drawing was made in 

 the Garden of the Horticultural Society, in August 1824. 



For the characters of the genus, and for the following valuable remarks, 

 we are indebted to our friend Mr. George Bentham, who has studied that 

 portion of Leguminosse to which Hosackia belongs with much care : — 



" This plant has much of the habit, as well as the inflorescence and 

 fruit, of a Lotus, to which genus Dr. Hooker has referred it in the Botanical 

 Magazine ; but, independently of the characters which may be drawn from 

 the position of the alee, and the capitate stigma, the pinnate, not ternate, 

 leaves, and the absence of the large foliaceous stipulse of Lotus, — cha- 

 racters which appear to be of importance among most of the Leguminosse, — 

 perhaps alone suffice for the adoption of the genus Hosackia proposed 

 by Mr. Douglas. 



** To this genus should be referred the Lotus sericeus of Pursh, which 

 Nuttall, on account of the position of the aloe, transferred to Trigonella, 

 under the name of T. americana, but which differs from the other species 

 of that genus by its fruit being cylindrical, and not reticulate, the size of 

 the carina, and its general habit. The leaves in this species are generally tri- 

 foliolate ; but then the two lower leaflets are seldom opposite, as in the truly 

 trifoliolate genera; and in the leaves of the more robust specimens, a fourth, 

 and even a fifth leaflet may often be observed : the stipules are so small as 

 scarcely to be visible. 



" Specimens of this species were also brought by Mr. Douglas from 

 the North-west coast of America, as well as of two other species, which 

 may be referred to the same genus, distinguishing them by the following 

 characters : — 



1. H. bicolor (tab. 1257); glabra, floribus umbellatis ebracteatis foliis 7-9- 



foliolatis. 



2. K. decuinbens ; pubescens, floribus umbellatis bractea 1-3-foliolata foliis 



4-5-foliolatis. 



Foliola alterna. Stipulce minutissimse aut nullee. Calyx profunde 5-fidus, 

 laciniis linearibus ssqualibus villosis. Petaloriim forma fere ut in H. bicolore. 

 Filamenta omnia antherifera. 



3. H. Purshiana; pnbescens, pedunculis 1-floris bractea sub flore mono- 

 phylla, calyce villoso, foliis 3- rarb 4-5-foholatis. 



Lotus sericeus. Pursh. jior. 2. p. 489. 



Trigonella americana. Nutt. gen. 2. -p. 120. Ser. in Dec. prodr. 



Foliola S8epii\s alterna. Stipulce minutissimse aut nullae. Calyx vil- 

 losus, laciniis linearibus coroUam subsequantibus. Corolla parva petalis vix 

 stipitatis. Stigma capitatum. 



4. H. parvijiora ; glaberrima, pedunculis 1-floris, bractea sub flore saepii!is 

 3-foliolata, calyce subglabro, foliis 4-6-foliolatis. 



Radix tuberculis pisiformibus munita. Planta tota glaberrima glau- 

 cescens ; foliola alterna oblonga obtusa. Stipulce minutissimse aut nullee. 

 Calyx subglaber, laciniis brevibus parce pilosis. Corolla ut in H. Purshiana, 

 sed minor. Stigma capitatum."
