MISSOURI BOTANICAL GARDEN BULLETIN 19 
The new central heating plant is an essential adjunct of 
_the greenhouses, and will supply not only the new range, but 
is now furnishing heat for all the buildings within the 
Garden. — pees 
Extending from the heating plant to the new greenhouses 
and under the main range is a service tunnel which contains 
‘all steam and water pipes and is of sufficient size to permit a 
_ hand-cart to pass from one end to the other. By means of 
manholes all dirt and trash from the greenhouses above can 
be discharged into a cart in the tunnel, thus avoiding the 
carrying of such material along the walks of the exhibition 
houses. The most modern heating and ventilating appli- 
ances are being installed, and a 50,000-gallon cistern will 
furnish all necessary rain-water. 
FLORAL DISPLAY DURING FEBRUARY. 
Visitors to the Garden now have access to the floral display 
in the north wing of the new conservatories, where more 
than 3,500 flowering plants, in great variety, are on exhi- 
bition. This is undoubtedly the largest exhibition of its kind 
ever held in the city. 
Entering the first section of the new houses (temporarily 
accessible through the north door of the service tunnel), one 
finds about 900 cinerarias in colors varying from white to 
blue, pink, red, purple and lavender, with many new and 
unusual shades. A small group of hardy plants of lilac, — 
hawthorne, crabapple and Deutza gracilis, which have been 
forced by the use of ether or hot water to bloom at an earlier — 
period, are arranged in the center around a large specimen 
palm (Acanthorhiza aculeata) and have attracted much atten- 
tion. On the side stages are exhibited the various garden 
varieties of azaleas (Rhododendron indicum), including 
Simon Mardner, Hexe, Deutsche Perle, Mme. Van der 
Cruyssen and Mon. J. Peters. Here also are South African 
bulbous plants (Veltheimia viridiflora), with pink tubular 
flowers on erect spikes; the belladonna lily (Hippeastrum 
Johnsoni), and the Chinese lilies (Lilium rubrum and 
Lilium album). The yellow poppy (Reinwardtia trigyna), 
a native of the East Indies, Senecio Petasitis, with yellow 
daisy-like flowers borne on paniculate spikes, and Primula 
kewensis, the latter a garden hybrid between P. floribunda 
and P. verticillata, with yellow flowers arranged in whorls 
‘one above the other, add to the variety of colors shown.
