JUNE 19, 1923 KRAUSE! NOTE SCHIZOCASIA REGNIERI 253 
BOTANY.—WNote on Schizocasia Regnieri. K. Krauss, Berlin- 
Dahlem. (Communicated by Paut C. STanpiEy).! 
Among the plants collected in the Republic of Salvador by Dr. 
Salvador Calder6én I have found a cultivated aroid which is to be 
identified as Schizocasia Regniert L. Linden et Rod. This species, 
which is said to be a native of Siam, is cultivated as an ornamental 
plant in the tropics and in several hothouses of European and North 
American botanic gardens, but, as in the case of some other much 
cultivated aroids, until the present time it has not been known in 
flower. Because the Salvadorean specimen was collected in flowering 
state, I can now give, in addition to my diagnosis in the Pflanzenreich 
and to the earlier descriptions in the Illustration Horticole and the 
Gardeners’ Chronicle, the following description of the inflorescence. 
ScuizocasiA Reenieri L. Linden et Rod. in Illustr. Hortiec. 17: pl. 2. 1887; 
Gard. Chron. 2: 328. 1888; Krause in Engl. Pflanzenreich IV. 23E:117. 
1920.—Tota planta usque 2.5 m. alta. Pedunculus teres superne circ. 1 cm. 
crassus. Spathae tubus convolutus anguste ovoideus, 4 em. longus, 2 cm. 
diametiens, lamina oblonga, apicem versus longe sensimque angustata, quam 
tubus 4—5-plo longior, expansa ad 5 cm. lata. Spadix in toto fere 2.5 dm. 
longus, in vivo ut videtur flavido-albus; inflorescentia feminea cylindrica 
3 cm. longa, 1.6 cm. crassa, interstitium sterile valde constrictum, 1.5 cm. 
longum, 6-7 mm. crassum; inflorescentia mascula cylindroidea, 4-5 cm. 
longa, 1.5 cm. crassa; appendix sterilis anguste elongato-claviformis, apice 
acutata, leviter curvata, 1.5 dm. longa, medio 1—1.2 cm. crassa, sursum atten- 
uata. Flores feminei 4-gyni, pistillis late ovoideis. depressis, 1 mm. longis, 
stigmate subcapitato leviter 4-lobo coronatis; flores masculi steriles synan- 
drodiis cylindricis depressis directione spadicis compressis atque elongatis; 
flores masculi fertiles synandriis cylindricis vertice truncatis medio leviter 
excavatis, fere 2 mm. longis, 1 mm. latis, thecis anguste oblongis fere totam 
longitudinem synandrii occupantibus. 
San Salvador, cultivated (S. Calderén 599). 
1A specimen of a plant of the family Araceae was forwarded recently by the U. 8. 
National Museum to the Berlin Botanic Garden for identification by Dr. K. Krause, 
the foremost authority upon this extremely difficult group. The specimen was col- 
lected by Dr. Salvador Calderén, an enthusiastic student of the Central American 
flora, who has made an extensive and valuable collection of Salvadorean plants and 
to whom the writer is under deep obligations for many courtesies extended during 
a recent collecting expedition in Salvador. From this material Dr. Krause has pre- 
pared the accompanying account, which completes the description of a striking orna- 
mental plant whose characters have been hitherto but imperfectly known.—P. C.S.
