Cereus Triangularis. Haw, or Macdonaldiae, (a night bloom- 

 ing species) with thick, massive triangular stems, although a 

 night flower cannot compare with the preceding. It sends 

 long rope-like stems from its thicker leaves, up high tree-trunks, 

 several plants on the edge of Victoria Park, Hamilton, afford- 

 ing a splendid illustration of the height attained. When the 

 plant has attained the summit of the tree it again throws out 

 its massive leaves. Flowers, pinkrish-white. 



Opuntia Vulgaris. Mill, (prickly pear. ) This is one of the 

 plants mentioned by the early discoverers in 1610. It may be 

 styled a prostrate, spreading, or creeping, shrub, with jointed 

 branches; leaves ovated, compressed, very thick and fleshy, 

 three to four inches long nearly as wide, with dense tufts of 

 slender barbed thorns or bristles, and in- open situations with 

 several long awl-shaped spines. Flowers are on the edge of 

 the joints, petals leathery-yellow followed by a crimson edible 

 frviit, two inches in diameter not unlike a fig, which, however, 

 before eating must be divested of its spiny and thorny coat. It 

 is common wherever sand prevails, but is not nearly so plenti- 

 ful as formerly. Flowers in the Summer mouths. Perennial. 



Opuntia Tuna. Mill, (prickly pear. ) Is given by Ivefroy, 

 but appears to have been confounded with vulgaris, unless it is 

 a smaller species. 



Opuntia Candelabra, (candle-stick plant or candelabra.) 

 Not to be confounded with the Euphorbia which bears the same 

 local name, the arms of the latter growing upwards, whereas 

 the arms of the plant being described grow laterally. It is 

 omitted by both Lefroy and Reade, probably having been in- 

 troduced since their time. It is strictly a garden cactus, its 

 peculiar right-angled stems form an upright, jointed stalk giv- 

 ing the idea of the name it bears. 



Natural Order, Crassulaceae. 



Bryophyllum Calycinum. Salish. (life plant or air plant; 

 floppers.) A succulent, brittle plant two feet or more high, 

 according to locality. Stems purplish, and green spotted. 

 Iveaves opposite, fleshy, serrate, or deeply toothed. Flowers, 

 pendulous, bell-shaped, one and a half inch long, green and
