3. Opuntidcei (plants having the habit of Opuntia). D. C. 

 prod. 3. p. 470. Stems composed of globose joints, horrific 

 from diverging prickles. Flowers tubular. Style much exserted, 



multifid at the apex. Perhaps a proper genus, intermediate 



between Cereus and Opuntia ? 



86 C. MONILIFORMIS (Lin. spec. 668. under Cactus) plant dif- 

 fusely procumbent, much branched ; joints globose ; prickles 

 strong, diverging. Tj . D. S. Native of St. Domingo. Plum, 

 ed. Burm. t. 198. Cactus moniliformis, Lam. diet. 1. p. 541. 

 Flowers and fruit red ; floral tube elongated, as in Cereus ; 

 limb short, spreading. Style much exserted. Stigmas 8-10, 

 spreading. 



Necklace-formed Torch-thistle. Shrub procumbent. 



87 C. SE'RPENS (H. B. et Kunth, nov. gen. amer. 6. p. 68. 

 under Cactus) plant creeping, branched, rather angular ; areolae 

 6-angled, prickly at the apex ; Howers tubular. Jj . D. S. Na- 

 tive of Quito, on dry hills on the banks of the river Guanca- 

 bamba, near Sondorillo. Flowers flesh-coloured; petals 8-12, 

 acute ; stigmas 8, approximate. Perhaps a species of Opuntia. 



Creeping Torch-thistle. Shrub cr. 



88 C. NA'NCS (H. B. et Kunth, 1. c. under Cdctus) plant 

 creeping and jointed ; joints terete, rather compressed, areolate, 

 prickly, a little branched. If. . D. S. Native of Quito, near 

 Sondorillo, on the banks of the Guancabamba. The rest un- 

 known. 



Dwarf Torch-thistle. Shrub proc. 2 to 3 inches. 



89 C. GRA'CILIS (Haw. in phil. mag. feb. 1827. p. 126.) plant 

 erectish, nearly terete ; old spines solitary, straight, an inch 

 long, but at first twin or more, white. fj . D. S. Native of 

 South America. Plant with the habit of Euphorbia hystrix, but 

 less spiny and the spines shorter. It appears to be more nearly 

 allied to C. nanus than to any other species. 



Weak Torch-thistle. Clt. ? Shrub. 



t The following species are in the gardens, but nothing is 

 known of them but the names. 



1 C. rosaceus, Hort. berol. 2 C. Deppii, Hort. berol. 

 3 C. incrustatus, Hort. berol. 4 C. exerens, Hort. berol. 5 C. 

 off mis, Hort. berol. 6 C. proteiformis, Hort. par. 7 C. Col- 

 mill, Sweet. 8 C. ovatus, Gil), (under Cactus'). 9 C. po- 

 lymorphus, Gill, (under Cdctus). 



Cult. The same kind of soil recommended for Mammillaria, 

 p. 160. will answer the species of this genus; and they are 

 easily propagated by cuttings, which if left to lie a few days 

 after being separated from the mother plant, strike root readily. 

 In order to have several species on one tree, insert them in a 

 plant of Pereskia. 



V. EPIPHY'LLUM (from ciri, epi, upon, and <j>v\\ov,phyllon, 

 a leaf; flowers rising from the flat branches, which appear like 

 leaves). Herm. par. bat. add. (ex Dill.). Haw. syn. succ. p. 

 197. phil. mag. aug. 1829. p. 108 Phyllarthus, Neck. elem. 

 1. p. 85. Cereus, 3. Alata, D. C. prod. 3. p. 469. Cactus 

 species of Lin. and others. 



LIN. SYST. Icosdndria, Monogynia. Tube of corolla very 

 long, middle-sized, or very short, furnished with remote, un- 

 armed scales, rising from the crenatures of the branches, among 

 small innocuous spines. Limb of corolla fugaceous, deeply 

 multifid, and as if it were polypetalous, rosaceous or more or 

 less of a ringent form. Branched, slender, hardly climbing 

 subshrubs, natives of South America, growing among rocks 

 or on the trunks of old trees ; branches much compressed, 2- 

 edged, thin but fleshy, lobately crenated, green, smooth ; with a 

 slender, woody, central axis. Flowers solitary, usually large 

 and showy, white, rose-coloured, or scarlet, rarely sweet-scented. 



The branches towards the roots are rather angular. The rest 

 as in Cereus, of which perhaps it is merely a section. 



SECT. I. NOCTU'RNA (from nocturnus, nightly, or in the night ; 

 in reference to the time at which the flowers expand). Haw. in 

 phil. mag. aug. 1829. p. 107. Corollas fugaceous, sweet-scented, 

 white, expanding alone at night ; tube very long.

4 E. VANDE'SII (Hortul.) branches flat or triquetrous, with 

 no spines in the notches, except when young, when there are a 

 few small ones at the base ; branches rather convex. fj . 

 D. S. A hybrid raised in the garden of the Count de Vandes 

 at Bayswater, from the seed of E. phyllanthoides, impregnated 

 by the pollen of Cereus speciosissimus. The flowers are large, 

 and of a deep red colour, and, upon the whole, it may be consi- 

 dered the most splendid of the genus. 



Count De Vandes' Epiphyllum, or Hybrid Cactus. Fl. June, 

 July. Hybrid shrub. 



5 E. JENKINSONII ; branches round or triquetrous at the base, 

 but always flat at the apex, with the notches more prominent and 

 spiny than in any other species of the genus; the branches are like- 

 wise more convex and firm. f; . D. S. A hybrid, raised from 

 the seeds of Cereus speciosissimus, impregnated by the pollen of 

 Epiphyllum speciosum. Cactus Jenkensonii, Hortul. The 

 flowers of this hybrid are large, and of a deep scarlet-colour, and 

 are said even to outvie in splendour those of E. Fandesii. There 

 are several other hybrids now in various gardens, raised from the 

 same parents as the present plant, which may prove even 

 superior in splendour to any of the genus, but they have not yet 

 flowered.

6 E. OXYPE'TALUM (Haw. 1. c.) tube of flower length of the
