Foliorum petiolus + 1772 — 30 cm. longus, supra canaliculatus, longe 

 (interdum fere usque ad geniculum) vaginatus, subtus decidue puberulus; 

 geniculum + 2 cm. longum ; vagina membranacea, mox dilacerata; lamina

 altéra rotundato-cuneata, altéra late rotundata; costa subtus decidue pu- 

 berula; venae primariae aperte patentes, utroque latere i 20 (15 — 25),

 gracilioribus, subparallelis, ± 5 interpositis. Pedunculus crassiusculus, 

 + 4 cm. longus, minute puncticulatus (juvenilis probabiliter pilosulus), 

 primum cataphyllo mox dilacerato cinctus. Spatha primum navicularis, 

 demum aperta, oblonga, + 15 X 8 cm , abrupte acuminata, extus laete 

 lutea, hic illic viridula, intus pallide flavescens, subeburnea. Spadixsessilis, 

 cylindraceus, + 11 cm. longus et l'/^ cm. crassus, obtusus, pallide fla- 

 vescens, subeburneus; ovaria ± 3 mm. longa, apice irregulariter 4—6- 

 angulosa, ^f: 2 mm. crassa, brevissime conoidea, loculis 6-ovulatis; stigma 

 parvum, subrotundatum vel suboblongum. 



The description is taken from a living spécimen cultivated in the 

 Buitenzorg Gardens under the name of R. oblongifolia Schott, flowering 

 June 1919. — R. oblongifolia Schott differs, according to the description 

 and figure given by Engler and Krause in Pflzrch, XXXVII (IV, 23 B), 

 Arac.-Monster. 31, fig. 11, by the proportionally shorter pétiole, scaberulous 

 Costa, smaller spathe and spadix, and the pluri-ovulate loculi of the ovaries. 



Habitat unknown. 



Raphidophora novo-guineensis, Engl., Pflnzrch, XXXVII (IV, 23 B), 

 Arac.-Monster., 20, fig. 3. 



GjELLERUP's No. 330 from Augusta River (Dutch New Guinea), deter- 

 mined by Krause, differs from Engler's diagnosis by the following char- 

 acters: Pétiole ± 4 cm. long, the sheath whether or not reaching the 

 knee which is 72—^/4 cm. long, the lamina obovate-lanceolate, + 10 — 15 X 

 3-4 cm., with the apex rather suddenly acuminate, the base subacutely 

 or obtusely cuneate or rotundate-cuneate, the primary veins + 10—12 on 

 a side, separated by 5—7 finer secondary and tertiary ones. — The spadix 

 is still too young to make out whether it may be another species. 



Raphidophora montana (Bl.), Schott, in Ann. Mus. Bot. L. B., 1,128; 

 Engl. & Krause, in Engl., Pflzrch, XXXVII (IV, 23 B), Arac.-Monster., 40; 

 Calla montana Bl., Cat. Hort. Btz. et Flora, 147. 



The Buitenzorg material, if correctiy determined, consists of 2 différent 

 forms: 1° Lamina ovate-lanceolate with a rather blunt or even rounded 

 base (conf. Schott's description); 2° Lamina obovate-lanceolate with a 

 subacutely rotundata-cuneate base (conf. Engler & Krause's description). 

 They hâve the spadix long-conoid-cylindrical, + 10—12 cm, long, [f: 172 

 cm. diam. below the middie, narrowed gradually towards the subacute apex.
