454 ME. J. G. BAKES ON THE 



Madagascar grasses under the name of Pcecilostachys, one species 

 of which is the plant I described in Journ. Linn. Soc. xx. p. 300 

 (Baron 1061, 3226) under the name oi Zophatherum geminatum, 

 and a second (P. Rildebrandtii, Hackel), founded on Hilde- 

 brandt's No. 3759. 



Eragbostis (§Pteroessa) maxima, Baker. — Megastachya 

 maxima, Bojer MSS. 



Erecta, robusta, foliis lanceolatis basi cordatis, spiculis 6-12-floris 

 oblongis complanatis in paniculam amplam laxissimam rhomboideam dis- 

 positis omnibus pedicellatis, rhacbilla continua, glumis sterilibus oblongis 

 floriferis rainoribus, glumis floriferis oblongis distichis lateralibus com- 

 plicatis, paleis hyalinis ciliatis. 



Stems erect, 2-3 ft. long. Leaves lanceolate, acuminate, thin 

 in texture, 4-6 in. long, |-| in. broad, cordate at the base ; 

 sheaths of the stem-leaves 2-3 in. long. Panicle erect, rhomboid, 

 very lax, 6-9 in. long and broad ; main branches erecto-patent ; 

 pedicels capillary, erect, |-| in. long. Spikelets oblong, flattened, 

 g-| in. long; rhachis not articulated. Outer sterile glume not 

 more than half as long as the flowering-glume. Flowering-glume 

 oblong, § in. long, glossy, drab, firm in texture, with flattened 

 sides and a scabrous keel. Pale oblong, hyaline, about half as 

 long as the flowering-glume, with a strongly ciliated margin. 

 Caryopsis ovoid, brown, glossy. — Baron 2551! Gathered also 

 long ago by Bojer. One of the most robust and ornamental 

 species of the genus. 



Nastus capitatus, Kunth. — Baron 2591 ! 



Cephalostachttim Ciiapellieri, Munro. — Forest of Andran- 

 galoaka, Dr. Parker ! Baron 2564 ! Mr. Baron's specimens have 

 heads composed entirely of the barren spikelets, and show well the 

 reduced bract-like leaves, hairy inside, which conceal the heads in 

 an early stage, and also the curious deciduous deeply fimbriated 

 lanceolate ligules. The three Bamboos which Mr. Baron and 

 Dr. Parker have collected all prove identical with specieg known 

 pr eviously.
