^78 Dr Martius on Antediluvian Plants, 
To this genus are to be referred : 
1. 'Euphorhites cicatricosus. 
With the faces more than an inch broad ; solitary, elliptical 
cicatriceSj eraarginato-bifid, above and below. 
At St Imbert, 
2. Eupliorbites sulcafiis. 
With the faces two-thirds of an inch broad ; twin linear, entire 
cicatrices. 
Palmacites sulcatus. Schloth. pi. 16. f. 1. 
From quarries in Silesia and at St Imbert. 
Perhaps Schlotheim’s Palmacites canaliculatus^ pi. 16. f. 2., 
differs only in having its proportions larger. 
The genus constituted by Sternbergs pi. 15., re- 
mains doubtful between Cactites and Euphorbites. With re- 
gard to Schlotheim’s PalmaciteS’ variolatus^ pi. 15. f. 3., I can- 
not affirm any thing with certainty, although it appears to ap- 
proach rather to Cactites. 
There is less doubt regarding another sort of fleshy plant, to 
which Sternberg gives the name of Variolaria Jicoides, The ar- 
borescent stalk, branched above, is every where furnished in the 
upper part and branches with lanceolate leaves, after the fall of 
which, there remains an orbicular cicatrix mamillated in the mid- 
dle, and which is the more prominent, the greater the degree of 
decortication which the specimen has undergone. We observe a 
similar structure in many succulent plants, which exhibit, when 
their bark is removed, knots of spiral vessels projecting from the 
alburnum opposite to each of the leaves, as I have represented in 
the Sempervivum arboreum,- The disposition and form of the 
leaves in Variolaria Jicoides^ as well remarked by Sternberg, cor- 
respond very well with Cacalia fieoides^ L. ; but the trunk is pro- 
portionally much thicker than we observe in the living plant ; 
and, althojLigh the petrified plant cannot, therefore, be referred 
to this species, it certainly bears indications of being allied to the 
tribe of Cacalire or Ficoidece. 
There remains for me now to speak of a very remarkable 
form, with branches attenuated upwards, and having the whole 
surface covered with foliiferous scales, arranged in an imbricat-
