sight, the species might be mistaken for D. fimbriatum, but it will be found 

 very different upon comparison. 



Most cultivators of stove orchideous plants find a difficulty in managing 

 the particular tribe to which this belongs : that difficulty is, however, com- 

 pletely overcome in the garden of the Horticultural Society, in which these 

 flourish more than almost any others. In that establishment they are 

 treated thus : — They are planted in perfectly rotten wood, in small pots, 

 which are covered with moss tied securely about them ; these pots are sus- 

 pended obliquely from the rafters of the front part of a small stove, in such 

 a way that the plants are not compelled to grow upright, but are allowed 

 to assume the pendulous or horizontal position which is natural to them. 

 Thus treated, species of the true Dendrobium habit, such as D. chrysan- 

 thum, nourish in a degree which is, at least, equal to that of their native 

 woods. The temperature of such a stove should never fall below 75° ; and 

 the dew point should be always near saturation." 



Phlomis floccosa. From Egypt to Boy ton, where it flowered last No- 

 vember, but is not likely to prove hardy. — Bignom'a Cherere. From 

 the conservatory of Lord Grenville at Dropmore. It is a native of 

 French Guiana, where the country people " manufacture the flexible 

 shoots of it and B. incarnata into baskets and broad-brimmed hats, which 

 act as umbrellas, keeping off both the sun and the rain ; they also use 

 the shoots as cord. A conservatory climber, preeminently beautiful among 

 the lovely race to which it belongs. Propagated readily by cuttings, and 

 requires no particular management beyond that of giving it plenty of room 

 to run." — Heuchenz micrantha ; 5axifrageae. From Colombia, and in 

 general habit resembling H. americana. — Polemonium cseruleum var. pili- 

 ferum. A hairy variety of the common Greek valerian ; raised in the gar- 

 den of the Horticultural Society, from seeds collected in the last arctic 

 expedition. — P. humile. From the same source. S A perennial 1| ft. high, 

 requiring a poor gravelly soil, but not dry. — Cotoneaster laxiflora ; Poma- 

 cea3. A hardy shrub, of uncertain origin, with small flowers tinged with red 

 in April. 



No. I. of Vol. III. for March, contains 



1306 to 1312. — -Malva Munroawa. From the barren plains of the Co- 

 lumbia, by Mr. Douglas. A hardy perennial, flowering from May to Octo- 

 ber, with vermilion-coloured roundish petals, and small gooseberry-like 

 leaves. It does not thrive in rich soil or peat earth, and suffers much from 

 rain. A coarse gravelly soil, among shaded roekwork, would probably suit 

 it better. Mr. Douglas, the discoverer, named this species in compliment 

 to Mr. Munroe,head gardener to the Horticultural Society. — Clerodendron 

 hastatum. A very handsome, rapid-growing, stove shrub from Hindustan. 

 It produces elegant, white, fragrant flowers ; and its deep green halbert- 

 shaped leaves are often stained with dark purple. Cuttings. — Blackwelk'a 

 jsadifldra ; Homalinese. A hardy green-house shrub, growing well in the open 

 border during the summer ; very handsome when in flower, and increasing 

 freely by cuttings. The blossoms, in a mass, have the appearance of those 

 of the bird-cherry : examined singly, they resemble nothing so much as an 

 elaborately finished shuttlecock. — Pentstemon venustus. " Found by 

 Mr. Douglas in the dry channels of rivers among the mountains of North- 

 west America. It increases freely either by seed or cuttings ; but is less 

 handsome than P. diffusus or ovatus. To be grown in perfection, it should 

 be treated as a biennial. It is apt to become unsightly when old. It is 

 extremely important to those who are in possession of seed of the rare 

 pentstemons, to know that this seed cannot be raised in heat, it is indis- 

 pensable that it should be sown in a cold frame, or all endeavours to 

 raise it will prove fruitless." — Cassia biflora. " A native of the West In- 

 dies, whence it was long since introduced to our gardens. In this country 

 it, like most other species of this beautiful genus, has been neglected, in
