SCROPHULARINE^. 
Generic Character See page 29. 
Specific Character. — Stem smooth. Leaves ovate, denticulate, and covered with white glandular hairs, 
each leaf having 7 smooth ribs. Calyx, teeth equal, sharp-pointed, and bending somewhat backwards. 
Corolla about twice the length of the calyx. Stamens somewhat shorter than the tube of the corolla. 
Peduncules nearly thrice as long as the calyx. 
This present subject, and the Youngii, which bear a very close resemblance to 
each other, are, without exception, the most beautiful plants of this genus known. 
It was our intention to have given this and the variegatus on one plate, but found 
it impracticable, without crowding and mutilating them both. The plant is a hybrid, 
raised probably between the rivularis and variegatus , but we are not acquainted 
with its history. It partakes much of the habit of the rivularis , and is a very 
profuse flowerer. It requires similar treatment to the M. roseus , p. 29, thriving 
the best in a light airy greenhouse. Our plants, just now come into bloom, will 
shortly be a perfect picture of flowers. The variegatus will probably be given in 
our next. 
Our drawing was taken at the end of February, from a beautiful plant in flower, 
in our greenhouse at Chatsworth. We believe it has not been previously figured 
in any work. 
Amongst those plants which possess peculiar irritability or remarkable 
appendages, none are more interesting than the Dioncea , Nepenthes , Sarracenia , 
and others, which have the power of entrapping insects. Plants having this 
property may be divided into three sections — 1st, Those which have hollow vessels 
or appendages attached to either their leaves or branches, containing a liquid, into 
which the insect having entered, is unable to return, as in Sarracenia , Nepenthes , 
Cephalotus, &c. 2nd, Those which entrap by their irritability, as Dioncea , &c. ; 
and 3rd, Such as entrap by the viscosity of their stems, &c., as Robinia , Sielene, 
and many others. 
First . Such as have hollow vessels or appendages attached either to their 
leaves or branches. The remarks made by Mr. Murphy, in the Horticultural 
Register, vol. i. p. 214, are as follow : — “ During my sojourn in the botanic 
garden of Trinity College, Dublin, where for some years I had the charge of the 
exotic plants, I took particular pleasure in availing myself of the excellent oppor- 
tunity which I enjoyed, of subjecting to the test of experiment whatever I found 
recorded concerning the habits of the several plants ; and especially with relation to 
the subject of this communication, being of opinion that much which is supposed 
to be known on this subject rests on little more than mere conjecture ; and with a
