362 Dr Graham^s Description of New or Rare Plants. 



neari-lanceolatis ; cymis terminalibus subtrifidis, decompositis ; invo- 

 lucre fimbriate ; appendice unico cyathiforme integro ; fructu glabro ; 

 seminibus verrucosis. 



Description. — Stem herbaceous, erect, branched, hairy, particularly to- 

 wards its extremity. Leaves (2 inches long, 10 lines broad) petioled, 

 lanceolate, unequally serrated, above irregularly sprinkled with dull red 

 spots, hairy, particularly below, where they are much paler wiihout the red 

 spots, and with very prominent middle rib and veins. Bracteae linear- 

 lanceolate, more entire, but in other respects resembling the leaves. 

 Cymes terminal, subtrifid, crowded ; primary rays trifid, and their sub- 

 divisions irregular. Involucre fimbriated, provided with only one cup- 

 shaped entire appendage. Male flowers on pedicels longer than the fila- 

 ment, anthers yellow, lobes bursting along the vertex. Germen green, 

 glabrous, but not shining ; styles revolute, white. Fruit smooth. Seeds 

 brown, verrucose. 



Seeds of this plant were sent along with specimens to this country from St 

 Louis, North America, by Mr Drummond. The plants flowered in the 

 greenhouse of the Botanic Garden in August and September. The only 

 difference between the cultivated and wild specimens arises from the 

 greater vigour of the former : they are larger, and the leaves are nearly 

 rhomboid. 



CEnothera perampla. 



O. perampla ; caule ramoso, tenuissime rubescenti, foliis runcinatis, pu- 

 bescentibus, lobo terminali maximo acuminato undulato basi sublo- 

 bato ; floribus axillaribus, omnibus difFusis ; calycis limbo petala sub- 

 rotundata integerrima sequante, tubo longissimo ; capsulis rauticis te- 

 trapteris, alis deorsim truncatis. 

 Description Root perennial. Stem herbaceous, robust and much branch- 

 ed, covered with very fine pubescence, green ; branches red only at their 

 origins, ascending. Leaves alternate, petioled, minutely pubescent on 

 both sides, undulate, dentate, runcinate, pale and with prominent veins 

 below, terminal lobe very large acuminate incised at its base, lower 

 lobes much smaller linear-lanceolate acute spreading. Flowers solitary, 

 axillary, very large and handsome, sessile. Calyx pale green, minutely 

 pubescent, nearly as long as the leaf; tube (4^ inches long) erect, red on 

 base when young ; limb (2 inches long) acuminate. Corolla white, with 

 a yellowish tinge; petals subrotund, entire, equal in length to the calyx, 

 3-ribbed and veined, the lateral ribs furnishing secondary ribs from the 

 outside of their base. Stamens included, declined ; filaments tumid at 

 their insertion into the throat of the calyx, subulate, pale yellow in 

 their lower half, white above. Anthers (three-fourths of an inch long) 

 linear, nearly entire at both extremities, versatile, bursting long before 

 the buds expand; pollen granules triangular. Stigma 4-parted, lobes 

 spreading. Style as long as the stamens, flattened, linear. Germen ob- 

 long, covered with the same pubescence as on other parts of the plant, 

 4-winged in its upper half, wings narrower upwards, truncated below. 

 Ovules very numerous, and closely imbricated. 

 The seeds of this very fine species were received from my friend Mr 

 Cruckshanks, and were probably gathered somewhere in the neighbour- 

 hood of Lima, but at a considerable elevation, for the plant is quite 

 hardy, and has flowered in the oj)en air at the Royal Botanic Garden 

 during the last two seasons. It is very deserving of cultivation. It 

 most nearly resembles O. taraxacifolia, but is distinguished from this by 

 its less prostrate growth ; by the green colour of its stem ; by the cap- 

 sule being more attenuated at its base ; by the absence of the conspi- 

 cuous glands and hairs, which are mixed in O. taraxacifolia with the finer 

 pubescence on the capsule and stem ; and by the tinge of yellow, not of 

 jmrple, in the flower. Its foliage more nearly resembles that of O. tri- 

 loba^ but it is distinguished from this by its much greater size, by its 

 nearly white flowers, and by its much darker foliage. From both these 

 species it is farther distinguished, by the flowers being altogether dif-
