phylla, Antidesmia, and Acalypha. At the end of the house, 
on the west side, are two plants of the curious West Indian 
ivy, belonging to the genus Marcgravia. On the east side 
of the house, at the south end, is a large collection of 
begonias, both on the benches and planted out underneath. 
Further on is the meadow-beauty family, largely repre- 
sented in tropical regions, to which belongs our native 
meadow-beauty, Rhexia virginica. Other families fol- 
lowing are the vervain, acanthus, potato, Madder and 
thistle, the last two near the north door. 
In house 5 is a collection of tropical ferns arranged in 
botanical sequence, thus bringing closely related families 
and genera into juxtaposition and enabling a comparative 
study of these plants to be made. It is only possible to 
represent in this sequence the position of the tree-ferns by 
very small specimens. These may be studied to better 
advantage in the larger houses. At the south end of this 
house is a part of the collection of cycads. Mucrocycas 
calocoma, a rare Cuban member of this family, is among 
these. There are a number of specimens of the American 
genus Zamia, including representatives from Florida and 
the West Indies. Other specimens, including the larger 
ones, will be found in the easterly house of the transverse 
range. 
The easterly of the smaller houses is divided into two 
compartments. House 6 is known as an East Indian 
house. Here are grown mainly such orchids as require a 
close humid hot atmosphere. Among the larger and more 
interesting of the genera represented are: Vanda, widely 
distributed in the East Indies and the Malay Archipelago, 
many of them with large and showy, often sweet-scented, 
flowers; Phalaenopsis, also native in the East Indies and 
Malay Archipelago; Angraecum, of tropical Africa and the 
Mascarene Islands; Macroplectrum, from Madagascar and 
the Mascarene Islands; Dendrobium, a number of species, 
a large Old World genus of over 500 species; Paphiopedi- 
lum, Venus-slipper, an Old World representative of the
