Spur much shorter than the lip, pedicels long. - . - . * 



Pedicels shorter than the flowen 

 Flowers subsessile or very short pedicelled; upper lip of the corolla emarginate. 

 Flower distinctly pedicelled, upper lip of the corolla entire. - • - 



Scales of the scape numerous, sub-cernuous (not appressed). - - . • 



Seed papillosely hispid, flowers yellow (scales on the scape sub-foliaceous). - 



Calyx lobes obovate or sub-orbicular, bracts and scales attached by the middle or above the 



base. 



Seed glochidiate, scales attached a little below the middle, lower lobe obtuse : (seed 



ovate oblong, acute at one end: lobes of the calyx very unequal: spur conical: 

 upper lip emarginate, under sub-orbicular, spreading, 5-toolhed: leaves orbiculato- 

 spathulate, scape flexuose). - * - - - 



Seed reticulated not glochidiate, scales attached by the middle, acute at both ends. 

 Flowers sub-sessile. 



Spur longer than the lower lip. 



Flowers somewhat remote, sub-racemose. ------ 



Flowers congested, spicate on the apex of the scape (the flowers of both these are 

 nigrescent in drying, but do not appear to differ in colour, hence I suspect an 

 error in the name ctBruha), ----- - 



lorter or about the length of the lip (lip large revolute on the margin, coverii 



and nearly concealing ^„_^. 



Flowers longish, pedicelled, seed scrobiculate.

 U. bifida. 



* U. caerulea and filicaulis appear to be varieties only of the same species. The former young with the first flcweri 



only open, the latter old with the short spike elongated into a fructiferous raceme. My specimens ghow, I think, the 

 transition.

XCV.— PRIMULACEiE. 



This order was first published in 1789 under the name of Lysimachice, b^ Jussieu, again 

 by Ventenant in 1799 under its present name, which Brown in 1810 adopted in preference to 

 the older and, as it appears to me, equally correct name, and has been followed by all subsequent 

 writers. In its habits it is very decidedly extratropical, hence is nearly unknown in the tropical 

 parts of India, four species only being as yet known to me, appertaining to the continental flora, 

 and one or J;wo more from the mountains of Ceylon. To this family the Primrose, Oxslip, 

 Cowslip, Loosestrife, and Pimpernel belong. The two last furnish Peninsular species, but on 

 the Himalays several species, of Primula are found. In Europe the Primulas flower in early 

 spring, or inhabit cold mountain tops and then flower in summer, while the Lysimachias aiid 

 Anagalles, flower in summer or autumn. This diflference in habit seems to account for, our 

 finding the latter only within the tropis, while the spring ones, loving a colder climate, do not 

 extend beyond the northern mountains.
