A very singular and most distinct species, two feet and more high, branched. Leaves principally from tlie 

 base, but by no means all radical, thick and fleshy, of three deep obcordate and lobed segments. Flowers 

 in large lax panicles, of a red-purple colour, with a very long spur, nearly glabrous. Petals all spathulate ; 

 the upper ones longer than the calyx,, much exserted. The D. nudicaule of Torrey and Gray, though 

 found by Mr Douglas, does not quite accord with this plant, and these authors do not notice the singularly 

 fleshy leaves.

My specimen of this plant shows that the flowers are sometimes in rather large lax panicles. Some of the 

 leaflets are more than two inches in diameter. 



Ord. III. PAPAVERACEA. Juss. 



The plants of this family in Mr Douglas' collection are possessed of peculiar interest ; affording, as they 

 do, eight new species, and three new genera ; of which latter, one is remarkable for the beauty of its blossoms, 

 as another is for its frutescent habit and rigid coriaceous leaves and fruit, an anomaly in the Order. Some 

 of these having been cultivated in the garden of the Horticultural Society, our valued friend Mr Bentham 

 has directed his attention to them, and has admirably characterized the new genera and species above alluded 

 to, In the Transactions of the Horticultural Society of London. His characters we cannot do better than 

 adopt.

" This little annual," Mr Bentham observes, " flowered " (the first season) " very sparingly ; but the fine 

 specimens transmitted by Mr Douglas in a dry state, promise that it may become as interesting to the horti- 



* There is a very distinct species of Berberis (Section Mahonia^, in Mr Andrieux's collection of " Plantce Mexi- 

 cans exsicc. n. 469," without any name, and with only the remark, " Locus proprius incertus." It may be thus 

 characterized : —
