434 HORTUS MORTOLENSIS 
too slender stems to produce any good-sized pith. If planted in 
a moist place the species attain a much more vigorous growth. 
For making the paper, the pith is first cut into pieces up to 
one foot long. These pieces are then rolled on a flat stone with 
the left hand against a very sharp knife, which is kept by the 
worker in his right hand, and in that way cut spirally into very 
thin sheets of uniform thickness. This work requires a steady 
hand and a keen eye, and is done in the middle of the night, when 
the makers are not liable to be disturbed. 
THEA SINENSIS. 
The “tea shrub” only grows with difficulty here, neither climate 
nor soil being adapted for it. It succeeds much better on the 
Italian Lakes. 
TILLANDSIA. 
Several xerophile species are grown epiphytically on trees. 
T. xiphioides has been cultivated in the pergola for nearly forty 
years. T. dianthoidea,* T. Durati, &c., do equally well; the 
former flowers almost annually. The strange TZ’. wsneoides was 
sent to us by Dr. H. Ross, of the Munich Botanic Garden, who 
collected it in Mexico in 1906. It does best when hanging fully 
exposed to the sun. We are indebted for the same plant and 
several other Tillandsias to Prof. D. Fairchild, of the United States 
Department of Agriculture. This Floridan 7’. wsneordes has much 
thinner branches than the Mexican one. 
TODEA BARBARA. 
A large stem of this fern was presented to Sir Thomas 
Hanbury through Prof. Penzig by the late Baron Ferdinand von 
Miller, of Melbourne. It lived for several years, but finally died 
for want of a suitably cool and moist place. 
TOoNA CILIATA. 
A large tree of a remarkably quick growth. It is almost 
evergreen, as it only sheds its leaves for a few weeks at the end of 
the winter, and is green again from the beginning of April. Young 
trees are, however, evergreen. As it fruits abundantly we have 
distributed quantities of seeds. It deserves to be largely planted, 
especially in town gardens, where shade trees are required. 
It wants good and fresh soil. 
According to Sir Dietrich Brandis (Forest Flora of North-west 
and Central India, p. 73): ‘the sap wood is whitish, the heart 
wood red or reddish brown, light, even, but open-grained, not 
strong, seasons readily, is easily worked and polishes well, some- 
what fragrant, when sawn or broken. . . . The bark is a 
powerful adstringent, and from the flowers a red or yellowish 
dye is made.”

* T. dianthoidea is the most commonly cultivated epiphyte in this country ; 
it is often met with on trees, on balconies, &c. Prof. O. Penzig has observed 
in 1892 in the Genoa Botanic Garden seedlings coming up spontaneously on 
the branches of Callistemon linearis. (Malpighia, viii. 1894, p. 461. t. 8.)
