NOTES FROM THE CONSERVATORIES. 



That it is now summer-time in South Africa is denoted by the 

 flowering of the aloes which are so numerous in that country. 

 The odd A. plicatilis, with its long strap-shaped leaves in two 

 ranks, is now sending forth its flowers ; A. ciliaris, with its long, 

 lank stems, is also flowering, as is A. insignis, of quite different 

 habit ; the common A. striata Hanbitriana, quite frequent in cul- 

 tivation, with its broad, flat, gray leaves with a narrow red margin, 

 is sending up its clusters of bright flowers ; and another species, 

 A. macrosiphon, quite unusual in collections, is at present in full 

 bloom. The gasterias and other genera related to the aloes, 

 representing the lily family so largely in South Africa, are also 

 blooming. All of these plants may be found in house no. 5. 



That it is now the time of summer in southern Africa is also 

 shown by the flowering of the heaths from that country, which 

 are now sending forth masses of delicate bloom in houses nos. 

 13 and 14. In house no. 6 two plants of another south African 

 plant, Crassula portulacea, are now laden with their pretty white 

 or rosy flowers. These plants, miniature trees in habit, are well 

 worthy of cultivation. They come from the dry regions of that 

 far off country. 



Those who have made journeys to our own southern lands 

 will recall that beautiful rose of those regions with its large 

 flowers of delicate hue — I mean the Cherokee rose. The writer 

 remembers well the beauty of this plant as it grew on fences 

 and hedges in central peninsular Florida. This rose is the Rosa 

 laevigata described from Georgia by Michaux in 1 803. It is also 

 known as Rosa Cherokeensis, R. Sinica, and R. Camellia. It is
