THE LADIES' FLORAL CABINET. 
Glossy-Leaved Lady’s Slipper (Cypripedium laevigatum). Flowers yellowish, with purplish dots and lines. 
(See Notes and Comments, page 192 .) 
I have only found it in open swamps, and do not think 
it is very common. 
The two sweetbriers are usually solitary or in small 
groups, and can easily be distinguished from each other 
by their fruit and prickles. 
Rosa rubiginosa, the larger sweetbriar, has numerous 
prickles, of unequal size. The larger strong and hooked ; 
the smaller, awl-shaped, and the fruit is pear-shaped, or 
obovate. In Rosa micrantha, the smaller sweetbrier, the 
prickles are uniform, and the fruit elliptical. 
By observing these special points you will be able to 
decide the type, and will not, I trust, enjoy your roses 
any the less for knowing their real names. One writer 
says: “ How cruel to make an honest country girl 
mouth Rosa rubiginosa for the sweetbrier that perfumes 
her garden! ” 
Is it cruel to teach or learn ? Of course, in con¬ 
versation generally it would be out of place to use 
any but common well-known names, but at the proper 
time and place it is well, to be able to speak of 
and know plants by their scientific names, and cer¬ 
tainly a necessity if you desire to intelligently commu¬ 
nicate with people in other sections of the country, for 
the common name here may be unknown there, and you 
can only make yourself understood by using the name 
known the world over. Louise Dudley.
