Oed. XIV. LIMNANTHACE^. Br. 
1. Limnanthes Douglasii. Br. — Lindl. Bot. Reg. t. 1673. Hook. Bot. Mag. t. 3554. 
Torr. et Gr. FI. 1 . p. 209. 
Oed. XV. OXALIDE^. De Cand. 
1. O. Oregana; acaulis, rhizomate elongate ramoso hie illic squainis dentato, foliis 
longe petiolatis foliolis (magnis) late obcordatis ciliatis subtus petiolis scapoque unifloro 
supi'a medium bibracteolato calycibusque pilosis pilis ubique ferrugineis, petalis obovatis, 
staminibus calycem subaequantibus. — Nutt, in Torr. et Gr. FI. \. p. 211. 
Mr Nuttall is quite correct in making this western Oxalis different from the O. Acetosella of Europe and 
Eastern America. It is much larger, the young leaves and buds and the petioles, peduncles, bracteas and 
calyx, and underside of the leaves and their margins, are clothed with ferruginous hairs. The description in 
Hook. FI. Bor. Am,, of O. Acetosella, belongs exclusively to that plant : the North-western specimens, and 
the remarks on them, belong to O. Oregana. It was first found by Mr Menzies in California. 
Oed. XVI. RHAMNE^. 
1. Rhamnus oleifolius. Hook. FI. Bor. Am. 1. p. 123. t. 44, 
1. Ceanothus incanus ; ramis brevibus crassis teretibus siccitate subpruinosis (vix pubes- 
centibus), foliis petiolatis lato elliptico-ovatis 3-costatis coriaceis glanduloso-serratis obtusis 
supra velutinis subtus pubescenti-canis, glomerulis multifloris densis sessilibus folio bre- 
vioribus — Torr. et Gr. FI. \.p. 266. — 13. minor; foliis angustioribus supra nudis. 
Ovary with three distinct lobes rising above the disk. Flowers white. 
2. C. thyrsiflorus. Esch. — Hook. FI. Bor. Am. 1. p. 125. Hook, et Arn. in Bot. of Beech, 
p. 136. Torr. et Gr. FI. \.p. 266. 
3. C. divaricatus ; ramis teretibus siccitate pruinosis, ramulis saspe spiuescentibus 
(spinis obtusis) patentibus, foliis elliptico-oblongis subcoriaceis tricostatis minute glan- 
duloso-serratis’supra glabris lucidis subtus pallidioribus nervis praecipue subpubescentibus, 
paniculis elongatis densifloris, floribus glomeratis (caeruleis). — Nutt, in Torr. et Gr. FI. 1. 
p. 267. 
In its flowers this bears a great resemblance to the preceding ; but the leaves are very different, much less 
strongly nerved, and the prominent angles of the stem are wholly wanting. The ovary, too, is smooth, and 
does not present three projecting" lobes as does that of C. thyrsiflorus. 
4. C. sorediatus ; ramis teretibus resinoso-verrucosis, ramulis patentibus subsericeis, 
foliis elliptico-ovatis obtusis subcoriaceis minute glanduloso-dentatis 3-costatis supra 
glabris subtus incano-pubescentibus ad nervos sericeis, glomerulis multifloris densis folio 
parum longioribus, (floribus cseruleis). 
* The short dense glomerules of flowers resemble those of the first species ; but these flowers are blue. 
The germen, too, is without lobes. The branches are copiously studded with resinous warts ; in the more 
exposed parts of the stem, frequently forming large patches.
