Primula denliculata. As the season advances a much larger 
variety of plants comes into flower, including numerous kinds of 
Androsace, Anemone, Achillea, Campanula, Chionodoxa, 
th^Plants Dodecatheon, Dianthus, Saxifraga, Gentiana, Primula, 
Iris, and Cypripedium. Many of the bulbous plants 
being leafless at the time of flowering, a few evergreen plants 
are introduced to supply the greenery that is lacking, such as 
Galax, Shortia, saxifrages, and Sedums. The gayest period is during 
the months of March and April, when, as a rule, more than a 
hundred different species and varieties may be seen in flower at a 
time, many of them rare.
