adénse, and is probably T. eréctum. He mentions that it is 
dark purple, although sometimes found white. 
There is a figure of T. eréctum, in Curtis’ Bot. Mag. 
for Feb. 1800; but although well drawn, and colored 
with truth, it is totally deficient in distinctness of the va- 
rious parts.

Observations made on plants gathered in various places 
in the vicinity of Boston, and on others transplanted into 
the garden with a view of noticing their habits. 
The three leaves are of a beautiful spring-green,

specimens more abruptly so than others, on very short 
petioles, the centre forming a kind of bed for the pedun- 
cle of the flower; they have three principal nerves, and 
two subordinate ones running near the margin, from all of 
which, smaller veins reticulate, precisely as in dicotyle- 
donous plants. 
e bud is ovoid, gradually tapering to an acute point ; 
it remains erect until a few hours previous to opening, 
when it droops between two of the leaves and is stiffly

without breaking. Æstivation valvular, sepals three, 
green, ovate-lanceolate, reflexed very soon after opening. 
Petals three, of a pure, delicate, opaque white, nearly 
the same form as the sepals but rather larger, also re-

and sepal ; anthers attached their whole length, with the
