comparatively small number of species being found in 
temperate regions, a few of which are in North America. 
Psilotum nudum is another plant related to the ferns, 
and of rather rare occurrence in cultivation. 
At the south end of the center bench is-a part of the 
cycad collection. Muicrocycas calocoma, a rare Cuban 
plant, is among these. There are a number of specimens 
of the American genus Zamia, including representatives 
from Florida and the West Indies. 
House No. 14. ‘The plants in this house, which is the 
same size as No. 2, are natives of warm temperate regions, 
or of the greater altitudes in the tropics; they are not 
hardy in our climate. The larger specimens of the tem- 
perate collections will be found in the Central Display House. 
The plants here are arranged in sequence of families as 
far as cultural conditions will permit, thus furnishing a 
collection for the comparative study of plant families and 
genera. The sequence begins on the right hand, as one 
enters from the Central Display House, and continues on 
and around this house, terminating on the west bench 
opposite the point of starting. First come the temperate 
ferns and their allies, and the members of the pine and yew 
families. Then follow the endogenous plants, those which 
are typified by the common lily, the grass, and the palm. 
Following these, and forming the greater part of the collec- 
tion, are the exogenous plants, those with net-veined leaves. 
Two curious plants among the endogens are members of 
the lily-of-the-valley family; they are the butcher’s broom 
(Ruscus aculeatus), and the double-tongue (Ruscus Hypo- 
glossum). The iris family, to which belong the flags, is 
represented by an example from Bermuda, known as the 
Bermuda iris (Sisyrinchium Bermudiana); to this genus 
belong the blue-eyed grasses of the United States. The 
amaryllis family has as a representative a yellow star 
grass (Hypoxis villosa) from southern Africa, much re- 
sembling the species found wild in the eastern United 
States. A few specimens of Paphiopedilum insigne are
