all very fragmentary. I was able to pick out a few steins which agree 

 well with those from Dominica ; the latter also are very meagre and 

 too im])erfect to base a new species upon.

Ohs. In addition to specimens of D. campanulata being named 

 L. inchoata by Stephani, a part of a small stem had been separated 

 and named as such by him ; this agrees with Prof. Evans' tigures and 

 with what I understand the species to be. As Prof. Evans points 

 out, the branch leaves of D. inchoata are smaller and narrower; but 

 as D. campanulata has well-developed c5" and $ on them, they cannot 

 be branches of D. inchoata, unless it is a very multiform species. 



D. Thwaitesiana (Mitt.), D. setistipa St. Under the name of 

 ''i. inchoata Meissn., Sumatra, ad folia Litsaece latifolice Blum., leg. 

 Korthals, ex herb. S. 0. Lindberg" there are specimens of this species 

 in the Manchester Museum ; the numerous ocelli, oblong lobule, bi- 

 setulose underleaves distinguish it from D. inchoata-, on many of the 

 leaves there is a somewhat large tooth at the postical base of leaf near 

 the lobule. The male plant had not been seen b}' Stephani ; but I 

 found a few on this specimen ; the amentula arise from the stem and 

 are long, 6 to 8 pairs of bracts, or at the apex of some of the branches, 

 then short, 3 to 4 pairs of bracts; bracts globose, lobule slightly 

 smaller than the lobe ; keel finely crenulate ; bracteoles only on the 

 lowest pair of bracts.

Ohs. This is a very distinct species; the remarkable involute 

 lobules readily distinguish it. 



Strepsilejeuxea inflexa (Hampe) S])ruce. TrachyJejeunea 

 inflexa Stephani. Hah. Mountain Lake, Dominica, Jan. 1896. 



Ohs. Leaves papillose, acute, -65 mm. X •■! mm., -7 mm. x '4 mm., 

 lobule *2 mm. X •125 mm. ; Stephani says " trigones large," the cells 

 appear to me to be roundish, with thick walls and no trigones ; under- 

 leaves rotund, bifid, three times broader than the stems, segments 

 acute. Specimens in the Manchester Museum — " Guadeloupe, ex herb. 

 Torrey, No. 21,000" — agree in every particular; leaves '6 mm, x '-l mm., 

 underleaves '3 mm X '3 mm., stem -1 mm. diam.

Ohs. A very conspicuous species, the white colour, large serrated 

 leaves, small lobules, large, slightly bifid underleaves distinguishing it 

 from other species.

06s. This is named Taxilejeunea dehiJis (h. & L.) by Stej^hani. 

 There are fortunately good perianths on the plant ; according to 

 Stephani's description, T. dehilis should have them three times longer 

 than broad, with the wings armate, with a long narrow rostellum ; 

 these are not twice as long as broad, with smooth wings and the
