342 TWO NEW SPECIES OF CITRIOSMA. 
rather large and conspicuous petals, and is pretty constantly, if not 
always pentamerous. The leaves bear very short points, like, but smaller 
than, those of S. sazatilis. I find no trace of gland-tipped hairs on the 
peduncle or calyx; but Vahl represents a few on the latter organ, 
although he deseribes them as subglabrous. Some states of S. pro- 
cumbens much resemble this plant, but are not likely to be confounded 
with it by a careful observer. Our plant may be characterized as 
follows :— 
S. nivalis, Lindbl. ; stem and branches ascending, ceespitose ; leaves 
subulate, mucronate, glabrous ; peduncles short, straight ; flowers pen- 
tamerous ; sepals very blunt, adpressed. to ripe capsule; petals rather 
exceeding the calyx, but falling short of the capsule, entire. —

The peduncles are apparently never hooked at the end ; they are very 
short, rarely exceeding a quarter of an inch in length. The flowers and 
fruits are small and rather narrowed downwards. The sepals are very 
blunt, and have a white diaphanous margin. .The ripe capsule does not 
greatly exceed the adpressed calyx. The branches and central stem 
appear to subdivide very frequently, and are, on the specimens from Ben 
Lawers, about an inch and a half long, but shorter on those from 
Norway. 
TWO NEW SPECIES OF CITRIOSMA, FROM BRAZIL. 
By BERTHOLD Seemann, Pu.D., F.L.S. 
In May last my attention was directed to two hot-house plants, cul- 
tivated without a name, in the garden of M. J. Linden, at Brussels. 
They had been introduced by him from the province of St. Catharina, 
Brazil, and their leaves emitted, on being touched, a very agreeable odour, 
which was found to originate in a number of minute oily dots with 
which the leaves were covered, the odour being different in both. I 
recognized in them two species of Citriosma, and on my return to
