the capsule, hiciniated. They are entirely destitute of ])lica; or 

 furrows, the transverse section being always circular. The cel- 

 lules of the tubular inouth are remarkable for being more elon- 

 gated than the rest, and the terminal ones, which constitute the 

 cilia, are longest of all ; Avhcreas in /. bidentata, however much 

 the calyx may be laciniated and toothed, the terminal cellules are 

 always the smallest. [The fructification of J. scutata oilers ex- 

 cellent marks of distinction from /. Bantriensis : it is lateral, with 

 a jjericluetium consisting of 2 — 6 leaves, entire or variously cut 

 at the extremity, and far smaller than the stem leaves ; and the 

 calyx is obovate with a trigonous denticulated mouth.] 



Cahjptra obovate, much narrowxr than the calyx and perfectly 

 free ; but in /. scutata it is of equal width with the calyx, and ad- 

 heres to its sides. 



Peduncle iucrassated, thicker than that of J. bidentata. Cap- 

 sule smaller, more nearly spherical, its valves of a deep purplish 

 brown hue, but in /. bidentata of a light brown. Seeds slightly 

 smaller, and spiral filaments much shorter than those of J. bi- 

 dentata. 



In var. /3. the stems are many times smaller than in the normal 

 form (though intermediate states occur) and of a loosely cellular 

 textm'e. Leaves broader than long, from a wdde base, usually 

 with a shallow triangular emargination ; the areolation slightly 

 wider than in the normal form. Stipules so minute as to be de- 

 tected with great difficulty. 



Var. y, which is also of humble size, has almost exactly the 

 habit of /. excisa, and might be mistaken for it if the stipules 

 were not observed. The stems are prostrate, subramose, opake. 

 Leaves almost horizontal, proportionally longer and subqu.adrate, 

 with a closer areolation. Stipules more uniform, yet occasionally 

 bifid. I found gemmce on this variety alone : the leaves which 

 bear them are closely imbricated at the extremity of a shoot, of 

 delicate textvire, remarkably laciniated and erose, reddish as well 

 as the gemmse themselves, which are almost spherical in shape. 

 The stipules which accompany the gemmiferous leaves are of un- 

 usual size, being scarcely smaller than the leaves themselves. 



All the states of this species are remarkable when growing, or 

 if moistened after having been dried, for their strong and rather 

 agreeable scent ; very different from that of /. bidentata, but not 

 unlike that of /. hyalina. Dr. Taylor likens it to " recently ciit 

 cedar-wood with a dash of sweet-briar." 



Although J. bidentata and scutata are the nearest allies of /. 

 Bantriensis, yet there are other species which approach closely to 

 it, amongst which are /. barbata, Schreb., /. Lyoni, Tayl., and 

 J.saxicola, Schrad.; but as the differences are obvious enough to
