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 Leguminose 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 ale, and the capitate stigma, the pinnate, not ternate, 
leaves, and the absence of the large foliaceous stipule of Lotus, — cha- 
racters which appear to be of importance among most of the Leguminose,— 
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 ale, 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 Ámerica, 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. H. decumbens ; pubescens, floribus umbellatis bracteá 1-3-foliolatà foliis 
4-5-foliolatis. 
Foliola alterna. Stipule minutissime aut nulle. Calyx profundè 5-fidus, 
laciniis linearibus sequalibus villosis. Petalorum forma ferè ut in H. bicolore. 
Filamenta omnia antherifera. 
3. H. Purshiana; pubescens, pedunculis 1-foris bracteá sub flore mono- 
phyllä, calyce villoso, foliis 3- rard 4-5-foliolatis. 
Lotus sericeus. Pursh. flor. 2. p. 489. 
Trigonella americana. Nutt. gen. 2. p. 120. Ser. in Dec. prodr. 
Foliola sæpiùs alterna. Stipule minutissime aut nulle. Calyx vil- 
losus, laciniis linearibus corollam subeequantibus. Corolla parva petalis vix 
Stipitatis. Stigma capitatum. 
4. H. parviflora; glaberrima, pedunculis 1-floris, bracteá sub flore seepiús 
3-foliolatà, calyce subglabro, foliis 4-6-foliolatis. 
Radix tuberculis pisiformibus munita. Planta tota glaberrima glau- 
cescens; foliola alterna oblonga obtusa. Stipule minutissime aut nulle. 
Calyx subglaber, laciniis brevibus parce pilosis. Corolla ut in H. Purshianá, 
sed minor. Stigma capitatum.” en
