CHAT^GUS. 



CRATiECxUS. 



culent greenhouse plants, natives of ! 

 the Cape of Grood Hope, with heads { 

 of red or white flowers. Tiiey should 

 be grown in sandy loam, and lime or ' 

 brick rubbish, and the pots should be i 

 well drained. Like ail the Cape , 

 plants, all the kinds of Crassula I 

 should have alternate seasons of ! 

 stimulus and repose. When they are i 

 groT\'ing, and about to flower, they \ 

 should be well watered,, at least once 

 every day, though the water should \ 

 never be suftered to stand in the ! 

 saucer ; and v/hen the flowers begin , 

 to fade, the supply of water should be | 

 gi-adually lessened, till, at last, very ' 

 little is given, and that not oftener , 

 than once a week. The plants are j 

 propagated by cuttings, which should \ 

 be laid on a shelf two or three days 

 to dry before planting, or they will 

 rot. When plants of Crassula are 

 not well drained, or if stagnant water 

 is retained round the roots, by letting 

 water stand in the saucer, the stems 

 are very apt to damp ofi". C. cocci n ea 

 and some other species were separated 

 from the others by Mr. Haworth, and 

 formed into the genus Kalosanthes ; 

 but this name does not appear to 

 have been adopted by many persons, 

 and the plants are still generally 

 called Crassula, both in nurseries 

 and private collections. 



Ceat^'gus. — Rosacece. — The 

 common Hawthorn, G. Oxyacdntha, 

 is so well knowTi for its fragrant and 

 beautiful flowers, that most persons 

 will be anxious to know the other 

 species of the same genus ; and, in 

 fact, several of the North American 

 thorns are the most ornamental low 

 trees we have in our gardens and 

 shrubberies. The species are all 

 hardy, and they all flower and fruit 

 freely, and are equally ornamental in 

 both states. Almost all the flowers 

 are white ; but the fruit varies in 

 colour, some being scarlet, some yel- 

 low, some purple, and some green. 



The fruit varies also in size from 

 that of C. spatkulata, which is not 

 larger than a grain of mustard-seed, 

 to that of C. mexicana, which is 

 nearly as large as a Golden Pippin, 

 The fruit of C. Azarolus, C. Arbnia, 

 and C. tanacetifolia, all large and 

 yellow, and that of C. odoratlssima, 

 of a bright coral colour, are all very 

 good to eat ; and many persons do 

 not dislike the haws of the common 

 Hawth orn. There are nearly a hun- 

 dred diflerent kinds of Crataegus, 

 including the hybrids and varieties ; 

 and of these thirty- one are varieties 

 of the common Hawthorn. The 

 handsomest species for their flowers 

 are the red-blossomed and double- 

 flowered Ha ^vthorns ; the handsomest 

 for their leaves are the diflerent kinds 

 of Cockspur-thorn {C. Crus gdlli), 

 C. ^yunctdta, C. 2>yrifdUa, C. pru- 

 ni folia (the leaves of which die off 

 of a deep red), and C. Celsii : and 

 the most curious for their fruit are 

 C. Dougldsii, C. mexicana, and 

 C. Orient alis. The earliest flower- 

 ing in spring are C. pwpurea and 

 C. nigra, the latter of which is said 

 to attract nightingales ; and the 

 Glastonbury -thorn, a variety of the 

 common Hawthorn, often flowers at 

 Christmas. C. Oxyacdnthapendula, 

 and C. 0. regince, Queen Mary's 

 thorn, have both pendulus branches ; 

 and C. 0. stricta, and C. tenaceii- 

 folia, grow stifi" and upright, like a 

 Lom'oardy poplar. 0. tanacetifolia 

 and C. odoratlssima have bluish 

 green leaves, Avhich look as though 

 they had been slightly powdered ; 

 and C. Crus gdlli splendens, and 

 several other kinds, have their leaves 

 of a shining dark blackish green. 

 C. Pyracdnthah&nevergreeen, and 

 has a very good effect, when trained 

 against a wall, from its shining leaves, 

 its bunches of pure white flowers, and 

 its brilliant scarlet fruit, which are so 

 abundant in winter as to induce the
