390 Gardening Toiir in Germany^ 



plants amongst them. The splendid Cereus senilis is propagated 

 here in a very simple manner : viz. the old plant is cut in two, 

 and the head planted, which produces a magnificent plant ; 

 the parent stem afterwards puts out young shoots every year, 

 which are cut off when they are about the size of a large hazel 

 nut; and, after they have lain for some weeks in a dry place, they 

 are planted in sand, and kept in a damp state till the young- 

 roots appear; when, by frequent watering, the plants will continue 

 to grow well. It is necessary, however, to observe that this 

 operation should take place in a warm dry house, by which 

 means the object in view will be sure to be effected. 



I saw in this garden, for the first time, two most beautiful 

 species of jEuphorbm in flower ; viz. ^uphorbm heterophylla 

 Karw. (pulcherrima Willd. Her.), and ^uphorbfa fulgens Karw., 

 the sight of which was quite delightful ; and, although I had 

 received, while at Bayswater, in the month of May, 1835, living 

 plants of both species, drawings of each, and dried specimens, 

 from my brother at Vienna, and was therefore well aware of the 

 extreme beauty of both plants, I cannot deny that I was quite 

 enchanted with them, and should have left them behind with 

 the greatest reluctance, had I not obtained several plants of 

 both euphorbias to take with me to England. The German 

 gardens are indebted to the Baron Von Karwinsky for these 

 splendid euphorbias. He found them in Mexico during his 

 scientific journey there, and brought living plants of them to 

 Germany. He would have preferred bringing seeds of them ; 

 but, from experience, he found that they lost the power of ger- 

 mination in less than twenty-four hours ; he therefore collected 

 several plants, and the two above mentioned are all that arrived 

 in Germany alive. There is a figure of the Euphorbia pulcher- 

 rima in Curtis's Botanical Magazine, t. 34-93., the beauty of 

 which speaks for itself; but, as the E. fulgens has not been yet 

 figured in any English botanical periodical, I shall give a short 

 description of it, and thus bring the young rivals to public view. 

 Evvphbvhia fulgens is an elegant and very ornamental plant of 

 the following characteristics. It is a branched, upright, leafy, 

 fi'eely growing, and freely flowering shrub. All its green parts 

 bear a glaucous bloom. Its shoots are slender, twig-like, round, 

 glabrous, and curved outwards in their terminal portion ; bearing 

 the flowers along this portion in groups, in the axils of the leaves. 

 The leaves have petioles nearly 1 in. long, and disks that are 

 lanceolate, tapered to both ends, entire, about 3 in. long, and 

 from half an inch to 1 in. across in the broadest part. The groups 

 of flowers are upon short stalks, and consist of from two to four 

 flowers (as they would be ordinarily called), each upon a stalk 

 about 1 in. long ; and each showy from its involucre, which is 

 of a bright red colour, and which has a tube of less than half
