NOTES OX BRIDELIA 193 



IV. Diagnoses op new Forms named above. 



Bridelia verrucosa, sp. nov. 



B. montana Brandis, Forest Fl. 450 (1S74) exc. synon. ; Hook. f. 

 Fl. Br. Ind. v. 269 in part (forma 2) ; non Willd. 



A B. retusa Spreng. foliorum forma, inflorescevitia nunquam 

 spicata ; a B. montana Willd., foliorum magnitudine nervisque later- 

 alibus ; ab utraque inflorescentite squamis magnis aliisque characteribus 

 facile distinguenda, 



Bridelia montana var. Stapfii, var. nov. 



A B. montana typiea (quam descripta vel depicta) nervis later- 

 alibus pluribus magis furcatis stipularum forma differt. A exemplo 

 in Mus. Brit, foliis magis obovatis subtus glaucis nervis lateralibus 

 pluribus differt. 



I have to express my thanks to Dr. Stapf at Kew and to 

 Dr. Rendle, Mr. Britten, and Mr. Baker at the British Museum for 

 kindly giving me much help. I should state, however, that Dr. Stapf 

 does not share my conclusions except in the case of B. verrucosa. 

 He would regard my three varieties of B. montana as three separate 

 species, all distinct from B. montana of Willdenow. 



MYCETOZOA ON THE MIDLAND PLATEAU. 

 By W. T. Elliott, D.D.S., F.L.S. 



In compiling either a local fauna or flora there are considera- 

 tions which might be noted other than a bare record of species. 

 Geographical distribution usually has been considered from areas that 

 are artificially marked out, such as counties. Horizontal range is 

 but a part of the distribution ; it is vertical range upon which 

 climate so much depends, as well as geological conditions, that 

 exercise influences viewed from the ecological standpoint. Therefore 

 this list of records of Mycetozoa embraces those found in the three 

 counties, of Warwickshire, Worcestershire, and Staffordshire, within a 

 radius of about fifteen miles of the city of Birmingham, and this 

 covers a large part of what is known as the Midland Plateau. If 

 the whole extent of these three counties were under consideration, 

 both the geological and geographical variations would be very 

 diverse, for the M idland Plateau forms a distinguishable natural area, 

 which varies in altitude from below the 300 feet to just beyond the 

 1000 feet contour-line. The variations in elevation in the area under 

 consideration lie between 130 and 1000 feet. 



Geologically, the stratum is mainly triassic, but in the south 

 there is an outcrop of lias formation, and in the north-west carboni- 

 ferous strata cover much of the Staffordshire area known as the 

 Black Country. In addition, there exist exposui-es of Palaeozoic 

 rocks in more or less isolated patches of varying area. A large part 

 of this country also is covered with the detritus of the glacial epoch, 

 and it is upon the character of this that much of the arboreal growth 

 depends.
