NOTICES OF NEW OR RARE PLANTS. 



four to eight inches long, and from one and 

 a half to three inches broad ; they are pu- 

 bescent, especially on the under side, and 

 the veining is prominent. Flowers very 

 showy, in axillary four to six-flowered ra- 

 cemes, longer than the leaves ; the tube of 

 the corolla is about an inch and a half long, 

 with a large spreading limb of five round- 

 ish, rose-coloured lobes, each having a small 

 oblique point ; these blossoms are produced 

 in the summer months. 



The species is a native of the Organ 

 mountains of Brazil, from whence it ap- 

 pears to have been first obtained for our 

 gardens by Mr. Lobb, the botanical collec- 

 tor to Messrs. Veitch, of Exeter : it was 

 introduced about 1841. It belongs to the 

 natural order Apocynacece. 



In cultivation, this species of Dipladenia, 

 in common with the others, requires stove 

 temperature, and a moist atmosphere when 

 making its growth ; it is, moreover, much 

 benefited by mild bottom heat, that is, heat 

 applied to its roots. Being a strong grower, 

 plenty of pot-room must be allowed to ob- 

 tain a good plant, but the pots must be 

 thoroughly drained ; a compost of equal 

 parts turfy loam and peat, opened if neces- 

 sary by the addition of sand, will be a pro- 

 per medium for its roots. If grown in a 

 pot, spiral training round a pillar-trellis is 

 most suitable ; or should any devotee of 

 flat, shield, or peacock's-tail trellises, be- 

 come possessed of the plant under notice, 

 if he will but attempt to train it over one 

 or other of these forms — it may help to 

 lead him to a better taste in this respect. 

 It may be increased by cuttings, planted in 

 sand and placed in a mild hotbed, where 

 they may be kept moderately close until 

 rooted. [Hort. Mag.] 



PiEONiA MouTAN piCTA. The Painted 

 Tree P(Bony. A new variety of the Tree 

 Pseony, sent from China in 1844, by Mr. 



Fortune. Leaves dull bluish-green, not 

 veined or tinged with purple ; in breadth, less 

 than some varieties : flower, the size of P. 

 Moutan rosea, and with something of its 

 appearance, but more semi-double : petals 

 with a rose-colored ground, streaked, stain- 

 ed and veined with rich deep rose, towards 

 the edges, especially in the inside ; rather 

 ragged at the points, something in the man- 

 ner of Parrot Tulips. It appears to be as 

 hardy as P. Moutan rosea, and to require a 

 rich sandy-loam to grow in, but protection 

 is advisable in spring. It will be increased 

 by grafting on the roots of PcEonia albijlora, 

 or by dividing the old plants when large 

 enough, and in a dormant state. It is very 

 handsome. [^Journal of the London Hort. Soc] 



HoLLBtiLLiA AccuMiNATA. This is a new 

 evergreen twining plant, from the East In- 

 dies, with quite the habit of H. latifolia, 

 from which it differs, in having very taper- 

 pointed leaflets, racemes whose stalks are 

 much shorter than the leaf-stalks, and pur- 

 plish flowers, not half the size : like that 

 plant, it is deliciously fragrant. Hitherto, 

 only male flowers have been produced. 



It has been treated as a hardy green-house 

 climbing plant, but it is probably hardy. It 

 grows freely in a mixture of sandy-loam 

 and rough peat, and is increased by cut- 

 tings. Its sweet-scented flowers, resembling 

 those of the orange in perfume, and nearly 

 evergreen foliage, make it a very desirable 

 plant, either in the green-house or the open 

 air. {^Journal Hort. <Soc.] 



Thibaudia pulcherrima. Beautiful Thi- 

 baudia. This superb green-house plant, 

 figured in the Flore des Serres for July, 

 1847, is well calculated to excite the admi- 

 ration of all lovers of showy and half-hardy 

 exotics. It is a vigorous growing shrub, 

 with large and thick lanceolate leaves, 

 and pale, smooth branches, which, at the 

 flowering season, are thickly loaded or
