indica. In comparing the latter species reference may be made to the 
original figures published by Bunbury (1) or those given by Feist- 
mantel (2). The leaves of Phyllotheca australis may be vertical or re- 
flexed as shown by Mc Coy, (8) Dana, (4) and Arber, (5) None of these 
species exhibits the greatly broadned cup form of verticil or the 
incurved apical portions of the leaves seen in the Brazilian type. The 
verticils with upward dilation of sheath illustrated bv Etheridge Jr., 
(6) as « Phyllotheca sp?» seem toapproach more closely to the plant 
in hand, though the free portion of the leaf is nearly straight. 
Itis desirable that additional and better preserved specimens of 
this interesting plant be collected in order to supply other data rela- 
ting to its habit, stem,and structure. 
The species is named in honor of Dr. Lauro Muller, Minister of 
Industry, under whose [authority the work of the Coal Commission 
has been prosecuted. 
Locality: North East of Minas, Santa Catharina. About 55 meters 
above the granite. Colleted by Doctor Seixas. Lot 3586, 
Phyllotheca (?) sp.

The cream colored sandy shales lying about 55 meters above 
the granite tothe North-East of Minas, in the state of Santa Catha- 
rina, contain numerous large Equisetaceous stem fragments consis- 
ting chiefly of vascular skeletons or pith casts in dark brown color 
and with more or less carbonaceous granular residue, the intervening 
softer tissues and cuticles being sometimes shown by a pale brownish 
tint contrasting but little with the color of the matrix. All are almost 
completely flattened. The broadest of these fragments does not ex- 
ceed 3.5 em. in width, and the longest internode, measuring 73 mm, 
forms part of stem 22 mm in width,the number of ribs being ten on 
the side in view.
