Van Alderwerelt van RosenburQH: Malayan Araceae 2. 215 



Plants occLirring in the Buitenzorg ' Herbarium or cultivated in tiie 

 Buitenzorg Gardens are distinguished from Enqler's diagnosis and figure 

 as follows: Pétiole to 25—50 cm. long, green, sheathing '/4 — '/2 (com- 

 monly '/s) '^s length, for the rest flattish or slightly canaliculate on the 

 anterior side throughout or in the upper part, occasionally narrowly or 

 acutely 2-marginate; sheath scariose, caducous; lamina dark-green above, 

 pale-green beneath, with the basai lobes separated by an obtuse or acute 

 sinus; primary veins less numerous (to 10 — 15 on a side) in the smaller 

 leaves. Spathe with the tube 2'/2 — 5 cm. long, ^/4 — 2 cm. diam., green; 

 lamina conoid-fusiform, 6 — 12 cm. long, yellowish or yellow-green. Spadix 

 with the féminine inflorescence conoid, the lower '/s—'/? connate with the 

 spathe, 2-4 cm. long, ^/4— 1 cm. thick; ovaries pale-green, ovoid or 

 oblong; stigma discoid, very pale-green; staminodes among the ovaries 

 présent, a few ones scattered hère and there but several to many others 

 more or less crowded at the base of the féminine inflorescence, about as 

 high as the ovaries, capitale, white, on a long and relatively thick stalk ; mas- 

 culine inflorescence conoid-fusiform, 4 -8 cm. long, '/2~1 cm. thick, separated 

 from the féminine by a conoid interstice '^\^—\ cm. long, provided with 

 scattered, solitary or 2-4-nate obconoid neuter organs which are white 

 at the thickened apex; fertile basai portion pale-yellow-brown or -grey; 

 stérile apical portion about as long as the fertile or shorter or longer, 

 ivory-white to pale-yellow-orange, bluntish; thecae commonly longer than 

 the filaments; staminodes subprismatical, the apex truncate, irregularly 3 — 6- 

 angular, very slightly depressed in the centre. 



Var. rubescensî Leaves, especially the pétiole, reddish to purple-brown ; 

 lamina with the basai lobes somewhat overlapping or separated by an 

 acute sinus. 



There are in the Buitenzorg Gardens 2 beds (XI B; X 21, 51) with 

 totally différent plants cultivated both under the name of Sch. Wigmanii 

 Engl. — No. 21, from Bornéo (NIEUWENHUIS No. 1096) does not agrée 

 with the diagnosis of that species and is nearly exactly agreeing with the 

 plant described by me as Sch. Engleriana. — No. 51, from an unknown 

 locality and collector, of which incomplète material gathered formerly has 

 been used by Enqler for his incomplète description of Sch. Wigmanii 

 and of which complète material has been gathered recently by myself, 

 proves that Sch. Wigmanii Enql. is but a form of Sch. latifolia MlQ. ; it 

 is distinguished from the variety rubescens in having the pétiole less 

 distinctly reddish and the basai lobes of the lamina often distinctly though 

 not much overlapping. 



Schismatoglottis Nicuwenhuisii, Enol., in Pflzrch, LV (IV, 23 Da), 

 Arac.-Philod.-Homal.-Schism., 112 p.p., fig. 69. 



This spécifie name' includes 4 totally différent species of which not a 

 single one agrées exactly with the entire diagnosis and figure given by EnGLER.
