MISSOURI BOTANICAL GARDEN BULLETIN 49 
These are very small and must be handled carefully. The 
should be sown thinly in pots, covered very lightly with soil, 
and, if no cold frame is available, each pot covered with a 
piece of glass which should be turned over daily to prevent 
the condensed moisture dropping down on the seed. The 
es will keep the soil moist and also hasten germination. 
t should be removed altogether after the seedlings have 
broken through the soil. metimes it is a good plan to 
place the pots containing the seed on inverted flower pots 
standing in saucers of water. This will keep the surround- 
Ings moist and likewise prevent certain crawling insects 
from feeding upon the young seedlings. The plants should 
be transplanted as soon as they produce a second leaf, for 
if left too long in the seed pan they fail to make good plants. 
Soil similar to that in which the seed germinated should be 
used for the potting, since calceolarias need a rich porous 
medium in which to develop. Care should be taken to 
select the weaker as well as the stronger seedlings, for the 
best colors are often found in the pecdiinice developed last; 
it is a general belief among growers that the stronger seed- 
lings produce the greatest percentage of plants with yellow 
flowers, or flowers in which yellow predominates. The young 
seedlings should not be exposed to the direct rays of the sun 
and the roots should not be allowed to become dry. 
When the young plants have four or five leaves, they 
should be repotted and allowed to develop until September, 
at as low a temperature as possible and under conditions of 
good ventilation. By this time the calceolaria plants are 
ready to be transferred to larger pots in which they oot 
remain over winter. High temperatures should be avoided, 
from 45 to 50°F. being ample. As soon as growth begins 
in the spring the plants are ready for their final shift into 
six or eight-inch pots. Pot firmly but do not pack the soil 
so that it will prevent free ramification of the roots. When 
the pots are filled with roots, manure water may be added 
occasionally, but as soon as the flowers appear, clear water 
only should be given. Herbaceous calceolaris grown in this 
way and kept in a cool moist atmosphere with an abundance 
of light and air will produce an abundance of flowers in 
March or April. ; 
Gloxinias——The genus Gloxinia was founded in 1785 
upon a plant obtained from Brazil and named in honor of 
a fan Gloxin a botanist of Strassburg. In 1817 another 
plant from Brazil, a was named Gloxinia 
speciosa and it was from this species that our present horti- 
cultural varieties of gloxinia originated. Later it was found 
that this parent of our garden gloxinias was not a true
