this treatment. The characters of the three closely allied species, as here 
treated, may perhaps best be given thus :— 
Leaves unbordered, pong ial comose, appressed when dry. B. campylothecium. 
Leaves with a narrow bro _ border, Serene sub- 
erect, not markedly c B. Billardieri. 
Leaves with a wide tek: whiti sh border, usually “spathulate, 
spreading when moist, usually markedly co co . B. truncorum. 
B. rufescens must, I think, on the whole, be referred here. The specimens 
in Wilson’s herbarium, * Tasmania, Oldfie 1d, 263; springs, Mt. Wellington, 
are stout, with the leaves interruptedly comose, widely obovate, very con- 
cave, with stout reddish nerve and strong bo rder. It is somewhat inter- 
mediate, as mentioned above, between B. Billardieri and B. truncorum, 
and I have seen some forms which are very difficult to place. 
The specimens labelled “ B. erubescens, "V. D. Ld., Gunn, 1691,” are very 
little different from B. Billardieri. 
Mitten, I think, did not know the true B. rufescens, and the remarks in 
the Handbook under that plant are rather misleading. 
It is probably common, but the records of this and the two allied species 
have been mixed up a good dea

I believe that Hook. f. & Wils. were quite correct in giving Bridel’s 
name to this. fie ylor in dering his B. leptothecium m does not compare

narrower in the Masiklisin plant, but wider capsules with straight neck 
occur there quite similar to those yee B. truncorum: I have, moreover, been 
able to see only a small range of specimens of the African form, 
and it is quite probable that tlie capsule t nae tere varies within the same limits
