when another species, very nearly allied to it, has none, is 
what physiologists fail to explain. 
Some other Tacsonias are in gardens, partly introduced 
by Mr. Hartweg. Among them is, we believe, the 7. Qui- 
tensis, a finer species than either mollissima or pinnatistipula, 
and if any one should possess a plant with the leaves of the 
former, but with no hairs on their upper side, and only two 
or three glands on their stalks, that plant will probably be 
the T. Auitensis, whose flowers are more than six inches long, 
and about three inches in diameter. 
Our drawing was made in the garden of the Horticultural 
Society in August last, from a plant raised from seeds col- 
lected by Mr. Hartweg in the gardens of Quito. 
Like T. pinnatistipula, this is a greenhouse climber, 
which may either be grown in a pot and trained on trellis, or 
be planted out in a conservatory border, and trained to a 
rafter. If potted, the soil ought to be very poor, otherwise a 
large trellis will soon be covered with wood and leaves with- 
out flowers. Where there is convenience, it will succeed best 
planted out in a bed or border, so that both roots and branches 
may have plenty of room. An ample supply of water is ne- 
cessary throughout the year, and air at all times when the 
weather is favourable. Fire heat should only be applied 
to keep off frost. It is easily multiplied by cuttings of young 
wood in the usual way.
