with larger quantities of Juniperus Virginiana.. It here makes 
but a low stubby tree of from fifteen to twenty feet high; but 
with very stout trunk in proportion to its low stature. — THOMAS 
MEEHAN. 
Wio DOUBLE-FLOWERED EPIGÆA REPENS is received from 
Worcester by Mr. Arba Pierce, who has gathered similar flowers 
‘from the same plant for several years. The doubling comes from 
the partial conversion of the stamens into petals, the outer and 
most transformed series more or less coalescent into a tube.— A. 
Gray. 
EXPERIMENTS ON Hysrrpization. — Mr. J. Anderson-Henry, one 
of our most skilful horticulturists, is contributing to ‘The Garden” 
the details of some important experiments on pure hybridization, 
or crossing distinct species of plants. He finds that in those 
plants which possess two series of stamens, one long and one short, 
the results vary essentially according as the pollen is used from 
one or the other series to effect the fertilization. He uses the 
rt stamens only in all cases where he wishes to cross a large 
a small species, and with the most successful results. The 
converse also he finds to hold good, remarkable hybrids being 
Produced by using the long stamens where he wished to cross a 
Small on a large species. The reason of this he considers to be 
that the shorter stamens contain pollen of smaller grains, and 
therefore better fitted to emit its tubes through the style to fertil- 
= the ovules of the smaller species, and vice versd. The plants 
chiefly Operated upon by Mr. Anderson-Henry are various species 
eranium, Rhododendron, and Azalea. — Academy. 
CALYPSO. 
(A rare Orchid of the North.) 
: BY W. W. BAILEY. 
Calypso, goddess of an ancient time, 
(1 learn it not from any Grecian rhyme, 
And yet the story I can vouch is true) 
Beneath a pine-tree lost her dainty shoe. 
No workmanship of mortal can compare 
With what’s exhibited in beauty there, 
And looking at the treasure ’neath the tree, 
The goddess’ selt I almost hope to see. 
The tints of purple and the texture fine, 
The curves of beauty shown in every line, 
With fringes exquisite of golden hue, 
Perfect the wonders of the fairy shoe.
