An imperfectly preserved leaf, but so characteristic that the species cannot be mistaken. 
It agrees in size and lobing almost entirely with that represented by Ludwig in the 
above-named treatise. It is much larger than those described by Ettingshausen. 
As intermediate forms occur between the large ones represented in pi. xxx. fig. 7 by 
Ludwig, and the smaller ones of the Bilin Flora, all would appear to belong to one 
species. 
This pretty coriaceous leaf is deeply pinnatisect, the lobes are acuminate, entire, 
somewhat bent upwards. The midrib is very strong, but the nerves are obscure, except 
on the best preserved lobes, where two prominent nerves are seen running towards the 
apex. 
This species appears in the Bilin Flora, and was also discovered at Frohnsdorf and 
Munzenberg. Dryandra Lyellii , Lath., from Alum Bay resembles it, but the lobes of this 
species are shorter, broader, and more bent upwards. It is doubtful if this leaf should 
be referred to Dryandra or the Myrica ( Comptonia ). 
XX. Ebenaceas. 
48. Diospyros brachysepala, Plates L. 13 ; LY. 8. Hr. FI. Arct. p. 117, pi. xv. figs. 10-12; 
xvii. 5 Ji , i ; xlvii. 5-7. 
Some remains of leaves and a calyx, which agree with those described in the ‘ Flora 
Arctica.’ The calyx is 4-lobed, with obtuse lobes (fig. 13 b, magn.). 
XXI. Gentianeae. 
49. Menyanthes Arctica , Hr., Plate L. fig. 16. Hr. FI. Arct. p. 118, pi. xvi. figs. 2, 3. 
I formerly knew the leaves only of this species ; but the Copenhagen Collection con- 
tains a fruit from Atanekerdluk, belonging evidently to Menyanthes. It is of exactly the 
shape and size of the living M. trifoliat'a, and consists of two carpels, opening when ripe. 
The whole fruit is 8 millims. long, and each carpel is 3|- millims. in breadth. The 
pedicel (10 b, magn.) is dilated at the apex, and as long as that of the M. trifoliata. 
Some indistinct lines indicate longitudinal nerves. 
XXII. Caprifoliacea;. 
50. Viburnum Whymperi , Hr., Plate XLYI. fig. 1 b. Foliis ovatis, dentatis, penniner- 
viis, nervis secundariis inferioribus ramosis, craspedodromis. Hab. Atanekerdluk. 
A very fine leaf, very like those of V. lantana, L., of Europe, and V. dentatum , L., 
and V. pubescens, of North America. The leaves of Pyrus Aria, L., have a similar 
nervation, but the dentation of the margin is very different.
