broad) bright green, edged with red when fading, jjetioled, cordate, acute,, 

 subpubescent on botli sides, sharply 5-lobed, and sharply inise-serrated, 

 5-nerved, and reticulato-veined, the nerves and their primary divisions 

 prominent on the back, serratures mucronate. Petioles spreading, as 

 long as the leaves, subpubescent, reddish, auricled at the base ; auriculae 

 ciliated, especially at the upper part. Cauline leaves very small, sessile^ 

 alternate, lanceolate, ciliated, subdentate, auricled, auricles similar to 

 those on the root leaves, and sometimes exist when the cauline leaf is 

 awanting ; higher up, the auricles having nearly disappeared, the cau- 

 line leaves degenerate into small, red, lanceolate, ciliated bracteae, placed 

 at each subdivision of the panicle, and at the base of the pedicels. Pe- 

 dicels spreading, pubescent. Flowers nodding. Calyx obovate, pubescent, 

 having 5 connivent, pointed teeth, yellowish-green. Petals 5, lanceo- 

 late, unguiculate, revolute, white, inserted into the margin of the calyx, 

 alternate with the teeth. Stamens 5, exserted, arising from the base of 

 the calyx, opposite to its segments ; filaments colourless, pointed ; an- 

 thers cordate, orange. Gei-men bivalvular, unilocular, green. Styles 2, 

 colourless, longer than the germen, straight, tapering. Stigmata minute, 

 ovules verj' numerous. 

 This pretty little plant flowered in the open border at the Botanic Garden 

 in June and July, having been raised from seeds collected by Mr Drum- 

 mond in the Rocky Mountains, probably on the west side ; for Dr Hooker 

 informs me he has it from thence by Menzies, Scouler, and Douglas, 

 differing from our cultivated ])lant only in being much larger. Mr 

 Douglas considered it T. Menziesii, Pursh, which I had at first marked 

 it ; but the expression " racemo filiformi subspicato," in the definition 

 of this writer, afterwards induced me to consider it distinct. 



Turritis patula. 



T. patula ,• caule erecto, glabro ; foliis radicalibus utrinque pilis ramosis 

 aspersis, petiolatis ; petiolis pilis simplicibus ciliatis ; siliquis secundis 

 patentibus, pedicellum octuplicatum £equantibus. 

 Description. — Stem erect, branched, smooth, shining, green. Radical 

 leaves (74 lines long, 3^ lines broad) lanceolato-elliptical, distantly ser- 

 rato-dentate, sprinkled with branched hairs on both sides, petioled ; jie- 

 tioles ciliated with simple spreading hairs longer than those on the 

 leaves. Cauline leaves entire, linear, lanceolate, smooth, sagittate at the 

 base, and stem clasping. Raceme terminal, greatly elongated while flow- 

 ering. Pedicels of the flower erect, green, smooth ; pedicels of the fruit 

 spreading, elongating from the bud, but not after the flowers are fully 

 expanded. Calyw shorter than the pedicel, smooth, green, edges of the 

 leafets colourless and transparent. Corolla scarcely larger than the ca- 

 lyx ; petals spathulate, white, slightly notched, and somewhat oblique 

 at the apex. Pistil equal to the longest stamens; ^ermew linear, flat- 

 tened ; style awanting ; stigma very small, glandular only on the upper 

 surface, and pitted in the centre. Siliqiue (14-2 inches long) spreading 

 ivide, almost straight or bent a little near the apex, linear, compressed, 

 with a strong central rib, and several smaller ones along each valve. 

 Seeds arranged in tw(i rows in each loculament, flat, bordered, embryo 

 applied to the edges of the cotyledons. 

 The seeds of this species were gathered in Captain Franklin's expedition 

 at Hudson's Bay, in Canada, and on the Rocky Mountains ; and by Dr 

 Scouler and Mr Douglas at Fort Vancouver. It flowered in the Royal 

 Botanic Garden in May. 



Turritis stricta. 



T. stricta ; caule erecto, glabro ; foliis omnibus glabris, subintegerriniis, 

 radicalibus in petiolam attenuatis, caulinis amplexicaulibus, sagittatis; 

 siliquis strictissimis, pedicello stricto, glabro, quadruplo longioribus. 



Description Root branching, fibrous. Stem erect, smooth, branched, 



leafy. Leaves erect, all smooth, lanceolate, entire, or, oftener, very spa-
