March.'] GREEN-HOUSE — REPOTTING. 205 



tected from the powerful rays of the sun. Drain the pots 

 well. (Soil No. 6.) 



Byninsviyms are all large bulbs from the Cape of Good 

 Hope, and will keep in the green-house during winter, but 

 are better where they can obtain a situation in the hot-house. 

 It is a splendid genus, containing about ten species. Some 

 of the bulbs grow to an enormous size, and all of them, while 

 growing, require a liberal supply of water ; but when dor- 

 'mant, it must be wholl}^ withheld, and they should have large 

 pots, to make tliem grow and flower in perfection. B. mul- 

 tijlbra, flowers scarlet and green; the leaves lay on the sur- 

 face of the pot. B. latirdma, flowers pale purple. B. Jose- 

 jihi'ii^ has splendid rose-colored flowers, and the most ad- 

 mired species of the genus ; the foliage spreading, half erect, 

 and glaucous; flowers numerous, and in large umbels, on a 

 stem two feet high, blooming successively : there is a variety 

 that has striped flowers. 



Several other species have been given to different genera. 

 B. falfdfa is now Ammocliaris falcdta \ B. margmcita, now 

 Imiiojia] and i>. cilh'dris hr\ovi Buphdne cillidr is. They all 

 flower in umbels, on stems from six inches to two feet ; flowers 

 lily-like, with six petals. (Soil No. 12.) 



BurcJiellt'as, two species. B. caj^ensis is a beautiful dwarf 

 evergreen shrub, with tubular orange-colored flowers, in large 

 terminal clusters; when well treated, grows and flowers freely, 

 and highly deserving of attention. B. parvijibra differs from 

 the above in the flowers being smaller and paler, and the 

 foliage more pointed. (Soil No. 10.) 



Cd-cfus : for descriptions of, see hot-house in May, 



CalccoJdria. This genus of plants has undergone a com- 

 plete revolution. Within these few j'ears, hundreds of superb 

 hybrid varieties have been brought to notice, many of them 

 truly splendid. With us the herbaceous kinds are very deli- 

 cate during summer ; they are generally all cut off by our 

 intense heat, or severe droughts. The shrubby varieties ap- 

 pear to withstand the vicissitudes of our climate better, though, 

 as yet, w^e confess we are not even altogether successful in 

 their summer culture. However, a few of them have done 

 well, and are C. angustifbUa, bright yellow, and in great 

 profusion; C. jupiter, brown and yellow; C. marjoridna 

 svperha, nearly scarlet ; C. similiiiy red and yellow ; C. ignea, 

 bright crimson ; C. meteor^ dark crimson ; C. Vulcan, dark
