by previously dipping them into boiling water, or even retaining them 

 there for some hours. I placed the specimen which I have described in 

 boiling water, in a vessel too shallow to admit it entirely. Nearly one- 

 half of each of the leaves was left above the water, and subsequently 

 dried rapidly under pressure : the portions which were submerged are 

 still (after six weeks) succulent and plump, thougli they have been al- 

 ternately placed under pressure and exposed to the air. 



Fritillaria leucantba. 



Y.leucantha; caule pauciflora, floribus axillaribus terminalibusque, so- 

 litariis ; foliis infimis oppositis ovatis apice attenuatis ohtusiusculis 

 multinerviis, superioribus verticillatis lineari-lanceolatis caiinatis apice 

 cirrosis. 

 Imperialis leucantha, Fischer., MS. 

 Description. — Bidb round, lobed, covered with a thick brown coat, which 

 separates in large fragments, splitting along the furrows between the 

 lobes. Stem simple. Leaves (3-4 inches long) bright green or slightly 

 glaucous, somewhat crowded about the middle of the stem ; the lowest 

 pair opposite, many-nerved, without conspicuous middle rib, ovate, ta- 

 pering towards the apex, which is rather blunt ; the others more or less 

 perfectly verticellated, linear-lanceolate, few- (3-5-) nerved, nearly flat in 

 front, and with a strong middle rib behind, extended at the apex into a 

 simple cirrhus. Flowers solitary, axillary or terminal, nodding, white, 

 at the base on the outside green, and within at the base sprinkled with 

 small purplish spots. Petals tipped with a green, callous, slightly pubes- 

 cent a])ex, the three outer ovate, the three inner obovate and broader, 

 all gibbous on the outside near the base, and there on the inside each 

 having a round green conspicuous pit containing honey. Stamens in- 

 cluded ; filaments straight, white, collected together in the centre of 

 the flower ; anthers j'ellow, linear, erect, very loosely attached. PistU 

 longer than the stamens; stigma trifid, slightly diverging; style straight, 

 somewhat clavate, 3-sided, twice the length of the anthers, colourless; 

 germen green, with six prominent, brownish, somewhat waved longitu- 

 dinal angles. Ovules numerous, in two rows within each of the three 

 cells of the capsule, ovate, flattened, attached by their apices to the cen- 

 tral receptacle. 

 This species, which I conceive should follow F. pyrenaica in the arrange, 

 ment, is a native of Altaica, and was obligingly communicated in Sep. 

 tember last by Dr Fischer to the Botanic Garden, where it flowered in 

 the open border in the beginning of May. 



Geranium albiflorum. 



G. albiflorum ; radice perenne ; caule herbaceo, erecto, dichotomo, sub- 

 angulato, subviUoso, pilis reflexis ; ramulis subteretibus villosis ; fo- 

 liis subpeltatis, 5-7-lobatis, lobis linearibus, nniltinervibus parce reti- 

 culatis, lateribus integerrimis, in radicalibus ad basin distaniibus ; pe- 

 duuculis axillaribus, bifloris, folio longioribus calycibusque glanduloso 

 pubescentibus ; petalia emarginatis, introrsum infra mediam lanato- 

 hirsutum. 

 Geranium albiflorum. Hooker, N. Amer. Flor. 



Description Root perennial. Stem herbaceous, branched, erect, dicho- 



tomous, shining, green, sparingly covered mth reflected hairs, scarcely 

 angular, swollen at the lower part of the joints ; branches towards the 

 extremities nearly round, and thickly covered with glandular pubescence. 

 Leaves opposite, siibpelta ,e, supported on long petioles, gradually shorten, 

 ing to the uppermost pair, which is subsessile, lobed, lobes cuneato-li- 

 near, incised in their upper half, in their lower entire, bright green above 

 and pubescent, below paler, sparingly pubescent, and only on the nerves,
