EUCALYPTUS TREES. Dat 
Asters, Sphenogynes and Athanasias, and three times 
as many Senecios (the latter including the pretty 5. 
elegans), none of all these coming amiss to a botanic 
garden. There are over 100 Indigoferas, many of 
them very handsome plants, in South Africa, none, I 
believe, ever subjected to the trial whether pigment 
can be obtained from them.* There are many Poda- 
lyrias and other leguminous bushes, which a horticul- 
turist here may well covet, when we see how much 
the few species hitherto introduced already contribute 
to the Spring glory of our gardens, and how complete- 
ly they are able to cope with the vicissitudes of our 
climate. As for bulbs, they also attain their maxi- 
mum in South Africa; this a glance at the bulbous 
flowers of any garden will testify ; but we know little 
yet of the Lilies and numerous other flowers of Cali- 
fornia and Texas, in a horticultural point of view— 
many modest, it is true. New transpacific commu- 
nication has lately brought these with their floral com- 
panions also within our easy reach. The heath-like 
Diosmez of South Africa, all charming bushes, num- 
ber (according to Dr. Sonder’s disquisition) 170 ; Ag- 
athosma alone counts 97 species, of which hardly any 
yet are existing here. These pretty plants, which 
cannot sustain themselves out of doors in the inclem- 
ent northern countries of Europe, we surely should 
like to grow here, along with our Australian diosme- 
ous Rutacez, in gay array, for pleasing contrast, or 
systematic and geographic comparison. If we also 
add the superb Australian Diosmeze (Boronia and 
Zieria 67, Eriostemon and allied genera 66), we ob-

*A search for dye in our native Indigofera gave negative results. We 
know, in all, about 250 Indigofer#, none European.
