1 4'0 British Flower-Garden. — Flora Australdsica. 



No. LXIlI.for May, contains 



249 to 252. — O'rchis longicornu. Handsome, with long flat spurs, and 

 velvety purple-lipped flowers. Native of the south of Europe, and grow- 

 ing freely in the Chelsea botanic garden. — TJhododendron arboreum. A 

 tree in its native country about 20 ft. high, in other respects like TJhodo- 

 dendron ponticum or cataubiense, but with flowers of the most brilliant 

 scarlet. Without doubt the finest species of the genus. In the neigh- 

 bourhood of London it requires a little protection in the winter, either to 

 be placed in a green-house or conservatory, or if planted in the open border, 

 it will need the protection of a mat, or some other covering in severe wea- 

 ther. In Devonshire and the more southern counties, it will succeed well 

 in the open air all the winter, thriving best in peat soil, or in very light 

 sandy loam, and may be increased by seeds or layers, or by inarching on 

 the R. ponticum, or other strong-growing sort. 



Mr. W. Smith, gardener at Combe Wood, has succeeded in raising nume- 

 rous hybrids between the present species and R. ponticum, and others be- 

 tween the present and Azalea pontica ; those will be still more valuable, as 

 they will be quite hardy, as well as curious and beautiful ; he has also 

 raised a great quantity of seedling varieties of Azalea indica, and mules be- 

 tween it and R. dauricum, and also a quantity of curious hybrids between 

 Cereus speciosus (phyllanthoides Decan.) and C. speciosissimus, some of 

 which are nearly of a flowering size. 



We agree with Mr. D. Don in uniting iShodora and Azalea with iJhodo- 

 d^ndron, as there are no proper limits between them, and we have suc- 

 ceeding in "muling" the whole of them together, the produce of which will 

 still unite them closer. 



Yucca pub^rula ; Tulipkcese. Equally hardy with the other species. — 

 Hormmum {konnao, to excite; supposed stimulant qualities.) pyrenaicum; 

 Labiatae. " A most beautiful perennial plant, which continues in flower a 

 great part of the summer, thriving well in the open border of the flower- 

 garden, but it is also a good plan to keep some plants in pots, that they 

 may be protected in frames in winter, as those in the open ground are 

 sometimes apt to be killed by excessive moisture ; those in pots can also be 

 turned into the borders at any time whenever they are wanted, and with- 

 out injury to the plants. It is certainly a plant that ought to be in every 

 collection, as it makes a fine show when in flower. It may be increased by 

 dividing at the root, or by seeds. If the seeds are sown as soon as ripe, 

 they will make flowering plants for the next summer."

No. XI. for April, contains 

 41 to 44. — Pomaderris (poma, a lid or cover, derris, a membrane; lid of 

 of the capsule) discolor ; iJhamneae. A handsome- 55 

 growing, bushy, evergreen shrub, with oblong dark 

 glossy green leaves, and yellow flowers in terminal 

 cymes, {fig. 55.) — Jcacia lunata (alluding to the 

 changes in its leaves, and also to their occasional 

 form); Leguminosse Mimoseae. An evergreen shrub, 

 with leaves more or less falcate, sometimes lunate, 

 and bright yellow flowers in racemes. " This 

 beautiful species is one of the most variable plants 

 of the genus in respect to leaves, and the size of 

 the flowers." — Hakea linearis. A beautiful bushy 

 evergreen shrub, with white flowers in fascicles, 

 slightly scented like hawthorn, and singular in 

 "appearance. It is of the easiest culture, and well 

 deserving a place by the side of a collection of
