shoots have a deep red margin, which is not the case with the mules referred 

 to. " A most desirable species, excelling, in brilliancy of colouring, even 

 the well-known C. speciosissima." — Acacia uncinata. " Very near A. 

 armata." — Podolobium trilobatum. " The leaves of this and some other 

 leguminous plants are opposite; a striking exception to the general fact, 

 that in that order they are alternate ; and a proof that what botanists con- 

 sider even the most fixed characters are occasionally liable to deviation : so 

 imperfect are the means we at present possess of distinguishing, by exter- 

 nal indications, the constitutional peculiarities of vegetation." — Justic/a 

 guttata ; Jcanthaceae. A tender stove perennial, flowering in August, and 

 increasing freely by cuttings. Presented by the East India Company to the 

 Horticultural Society. It is a native of the Pundua Mountains. " The 

 marking of the corolla with deep blood-red spots, upon a greenish ground, 

 is exceedingly pretty ". when closely examined, it will be found to arise 

 from the presence of a deep crimson colouring matter, filling here and there 

 the cavities of the cellular tissue of the parenchyma, and not existing in 

 that part which forms the ground colour. When will natural philosophy 

 tell us why contiguous spaces on a plane surface, the functions and anato- 

 mical structure of which are uniform vary thus in the matter they secrete ?" 

 — *Lobeh'« purpurea. A handsome half- shrubby plant, from Valparaiso, 

 " growing in the open border in the summer, but requiring protection in the 

 winter. It does not ripen its seeds, and can only be increased by cuttings, 

 or division of the crown of the root." 



iVb V. for July, contains 



1335 to 1341. — Brunsvigea grandiflora, A noble addition to the genus ; 

 no doubt a native of the Cape of Good Hope. Approaching B. striata in 

 flower, and B. Josephine in bulb. — Kennedys monophylla var. longira- 

 cemosa. Raised from New Holland seeds, by Mr. Rollison of Tooting. 

 A green-house plant, of much beauty, propagated readily by cuttings. — 

 Pothos scandens ; ^(roideae. Imported from China by Mr. Tate of the 

 Sloane Street nursery. It roots into the bark of trees, in the most shady 

 forests of India. — Tillandsia stricta ; Bromek«ce<£. From Buenos Ayres 

 and Brazil, to Peter Kendall, Esq., a zealous cultivator of curious hot- 

 house plants, who presented it to the Horticultural Society. " This is 

 among the most beautiful of its tribe, and one that is very easily culti- 

 vated. Mr. Kendall finds it succeed remarkably well with the following 

 treatment : — In June he takes it out of the stove, and suspends it from 

 a wall in the open air, where he leaves it without water, attention, or pro- 

 tection, till the succeeding October; thus creating a sort of artificial win- 

 ter. When the time for placing it again in the stove arrives, it is found 

 withered, discoloured, and, in appearance, half dead : as soon, however, as 

 it is again submitted to heat and moisture, it recovers rapidly, commences 

 a new and vigorous growth, and in the course of a few weeks loses all 

 traces of its previous sufferings, assuming a rich healthy vegetation. After 

 throwing out suckers from each side, it shoots up its spikes of bright blue 

 flowers, which begin to open in March, and endure till the end of April : 

 when the period for a cessation of growth draws near, its parts harden, its 

 flowers fall away, and by June it is ready again to undergo the same treat- 

 ment as before. It is no doubt desirable to create an artificial winter, or 

 cold season, for all tropical plants, if it be possible, but this is generally 

 impracticable; and although Mr. Kendall's management succeeds with this, 

 and two or three similar plants from the same part of the southern hemi- 

 sphere, it by no means follows that it can be applied generally ; on the con- 

 trary, we know, from experience, that Brazilian and West Indian epiphytes 

 of the orchis tribe are destroyed by it." — Passiflora ligularis. Nearly 

 related to P. quadrangularis and edulis ; the fruit is said to be about the 

 size of an orange, and eatable ; the leaves are entire. — Justiciar quadrangu-
