flowers generally. 2. — Species more slender in growth, and trailing or pendant in 

 habit. 3. — Night-flowering species, which are so interesting to those who possess 

 them because of the peculiarity indicated, apart from the beauty of their handsome 

 blooms. 



Globose and Columnar Species. 



Cereus azureus.— Chili. Somewhat rare ; sterns blue. 



C. Baumanni.— Tall, slender growth; flowers freely 

 produced ; vermilion and orange. 



C. Berlandieri (synonymous C. repens and C. 

 Deppi). — Texas and Mexico. Creeping habit ; 

 flowers 4 inches across ; purple and rose. 



C. Blanki.— Mexico. In habit resembling the pre- 

 ceding ; flowers deep-rose, flushed crimson.

 tive, bluish-green stems ; large white flowers.

 with erect flowering stems ; flowers bright red. 



C. enneacanthus.— Texas. Dwarf stems, with tufts 

 of long spines ; flowers purple. 



C. gemmattjs. — Tall-growing ; large yellowish-green

C. Jamacaru. — Tall, branching, pubescent stems, 



which are specially attractive by their colour, 



which is nearly blue. 

 C. multiplex. — South Brazil. Globose-stemmed ; 



flowers 6 to 8 inches long, and the same in width ; 



white. 0. multiplex cristatus is a variety with 



curiously fasciatcd stems. 

 C. peruvianus. — Peru. Stems tall, spiny, and 



glaucous blue ; flowers large, white, tinged with 



red. C. peruvianus monstrosus, a form with curious 



irregularly twisted stems, is known as the ' ' Rock

C. PROCUMBENS. — Mexico. Spreading, prostrate 

 stems, from which upright branches grow to a 

 height of 3 or 4 inches ; flowers rose-purple. 



C. speciosissimus. — Mexico. The most popular of all 

 Cactuses, and deservedly named the "most 

 beautiful ' ' ; slender stems ; flowers, freely pro- 

 duced ; intenso crimson or violet. 



Semi-Scandent or Trailing Species. 



C. flagellipormis.— Peru. Stems prostrate. Most 

 effective when grafted on the Pereskia or strong- 

 growing Cereus stocks ; or, grown in baskets, the 

 long tail-like stems arching gracefully. We have 

 had them 6 feet in length, covered with bright 

 rosy-red flowers. 



C. Mallisoni. — A hybrid obtained by fertilising the 

 flowers of C. speciosissimus with pollen from 



C. flagelliformis, the parentage boing unmistak- 

 able ; flowers 4 inches across ; bright red, with 

 pale yellow stamens. 

 C. serfentinus. — South America. Stems round, 

 green, and spiny ; in a young state stiff and erect, 

 afterwards lengthening considerably and requiring 

 support; flowers freelyproduccd, large andfragrant; 

 coloiu', pinkish white inside, purplish outside. 



Night-Flowering Species. 



C. estensus. — Trinidad. Stems long, rope-like, and 

 bluntly triangular ; flowers developed along the 

 stems somewhat sparingly; colours, yellow, green, 

 and red. 



C. ftjlgidus. — Hybrid ; stems bright green, and slow- 

 growing ; shy flowering ; flowers G inches long 

 and the same in diameter ; bright orange scarlet. 



C. GRANDIFLC-rus.— West Indies. Truly a grand 

 species ; stems almost cylindrical, bearing tufts of 



wool and short stiff spines; flowers freely 

 produced by strong plants, lasting a few hours 

 only, but may be kept a whole day if cut (before 

 expanded) and placed in water. They are about 

 1 foot across ; sepals bright yellow ; petals pure 

 white, arranged cup-like, enclosing numerous 

 yellow stamens and a club-shaped stigma. 

 C. G. Maynardi. — This, though unfortunately rare, 

 is a splendid hybrid between grandiflorus and
