The Tremandracex, now for the first time represented 
in this Magazine, are a purely Australian order. 
Tetrathecas are among the oldest of the one-time 
favourite “ New Holland” plants, some of them having 
been introduced into cultivation a century ago. There are 
twenty-one species, most of them worth growing. The 
best known, 1. ericifolia, T. hirsuta and 1. pilosa, like most 
of the genus, have drooping flowers, and are none the less 
beautiful on that account. . thymifolia, even in dull 
weather, bears its flowers erect with the purple anthers 
exposed to view. 
The order comprises only two other genera, namely, 
Flatytheca, which has one representative, the elegant 
P. galioides, and Tremandra, a genus of two species. 
Descr.—A much-branched, pubescent undershrub, with 
slender, erect, terete stems, one foot to one and a half 
high. Leaves verticillate in threes or fours, ovate-elliptic 
or lanceolate, acute, with recurved margins, about four 
lines long by one to two lines broad. Pedicels longer 
than the leaves. Flowers tetramerous. Sepals ovate- 
lanceolate, acuminate, very hairy, nearly one line and a 
half long. Petals obovate, four lines long, each enfolding 
a pair of anthers when in bud. Anthers four-celled, with
