INTRODUCTION. 
The examination and description of the Scrophularineae con- 
tained in the East India Company’s herbarium, since presejited to 
the Linnaean Society, had been long since entrusted to me by my 
friend Dr. Wallich ; but the determination of the Labiatae having led 
me into a general monograph of that order, I had been long unable 
to devote any time to the Scrophularineae. I now, however, take 
the first opportunity of submitting to the public the following Enume- 
ration, to which 1 have added such other East Indian species as I have 
received from the rich stores of Mr. Royle and Dr. Wight, or which 
I have been enabled, through the kindness of my botanical friends, 
to examine in the extensive herbaria we possess in this country. 
The order of Scrophularineae, one of the most extensive of the 
Monopetalae, is also in general a very natural one, but on the other 
hand, there are some genera which connect it so closely with neigh- 
bouring tribes, that a great deal of uncertainty has prevailed about 
the exact line of distinction to be drawn. With regard to its own 
genera, also, although some have been grouped together, and de- 
scribed in detail by Botanists of great merit, yet the circumscription 
of others, and especially of the East Indian ones, is yet in a state of 
great confusion. I found it, therefore, necessary to go through the 
whole order, as far as my materials allowed, and to distribute into 
groups all the genera I was acquainted with. I took advantage of 
the offer of my friend Dr. Lindley, to publish a short abstract of my 
ideas on this subject in the Botanical Register for June 1835, but 
the limited space allow'ed me in that work, prevented my entering 
into any general observations, w'hich I would now' beg leave to sug- 
gest, together with such corrections and additions as I have already 
been enabled to make. 
The nearest affinities to Scrophularineas are undoubtedly the Sola- 
neae, through the medium of the tribe of Salpiglossideae ; so much 
so, that it becomes necessary to separate them by a purely artificial 
distinction, considering as Solaneae such genera as have the plaited 
corolla and 5 stamina, and as Scrophularineae all those in which 
either the fifth stamen is w'anting, or the sestivation of the corolla
