Cavendishii, smallish leaf, centre parts of a dull green, the edge beautiful 

 silver grey; a very pretty pot-plant, 



A urea densa, fine variegation, good for pots. 



Aurea maculata, sometimes nearly a whole shoot of one year's growth will 

 come silvery white. 



Marginata Cullisi should be in all collections; either as a wall plant or for edg- 

 ings it is unequalled. 

 . Palmata, beautifid golden variegation. 



Rhombea, another fine silver-edged sort. 



Eaegneriana, Sagittaefolia, and several more, should not "be neglected 

 if a good collection is wanted. There are several varieties very much 

 alike, which should not be neglected, as a good assortment cannot be 

 had without a few resembling each other a little. Those that are 

 more properly designated " Tree," or " Bush Ivies," are more slow 

 growers in a general way ; but nice young healthy plants, with proper 

 care and attention, soon form handsome little trees ; several of them 

 bear berries in winter, which adds greatly to their appearance and 

 value as a winter decoration plant. There are a good many in this 

 section, but 12 or 15 of the most distinct varieties are ample. When 

 the real value of Ivies is found out, they cannot fail to be more ex- 

 tensively used ; and no doubt some one will take them up, and, 

 judging from what has been done amongst them the last few years, 

 will bring them to as great perfection as the Golden and Bronze 

 Geraniums. Edgings in winter and spring of a Mrs Pollock-like Ivy, 

 with Imperial Blue Pansy, is not too much to hope for. A. H.

Ax)lielexls Jmmilis. — In one or other of its several varieties this is 

 the best known, and the best worth growing, of this pretty group of 

 greenhouse plants. There are several other species which have been 

 introduced from time to time, but none of them have risen in popula- 

 rity, as decorative plants, so much as the one named above. All the 

 species w^ere better known formerly under the names Helichrysum or 

 Helipterum — two genera of popular annuals with everlasting flowers. 

 The flowers of Aphelexis, too, are everlasting, but resemble more 

 closely in form and colour Ehodanthe than Helichrysum. Aphelexis 

 humilis is a pretty plant and interesting, whether in flower or not, 

 somewhat straggling in habit, but capable, with a little care and skill, 

 of being manipulated into specimens of perfect symmetry, and when 

 well bloomed it is an ornament of a choice and distinct kind, lasting 

 for many weeks with little diminution of its freshness. There are 

 several varieties differing from the ordinary form in the size and tint 

 of the flowers. Those of the ordinary humilis are pink, deeper exter- 

 nally than inside; in A. h. macrantha they are larger, with deeper
