Koh Kahdat, sandy seashore (No. 572 a). 
Area: Madagascar and both coasts of tropical Africa (acc. to Bot. Maga- 
zine), The Concans, coasts of India, Ceylon, Malay Peninsula, Malay and Pacific 
Islands, North Australia. Commonly cultivated in the Tropics of the Eastern 
Hemisphere. 
Note. The TY. viridis Hemsley (Hook. f., Icones P]., 2515—16, 
1897) is nearly allied to the above species, and by the scarce material 
a distinction between these two species is hardly possible.

— — var. breviscapa nov. var. 
Rhizoma subterranea erecta, brevis; petiola foliorum laevia, 
infra in vaginas dilatata, 10 (8—12) cm. longa; folia lanceolata vel 
elliptici-lanceolata, longe acuminata, 20 (15—30) cm. longa, 5 
(3—7) cm. lata, levia, petiolo subduplo breviora; scapus 
floriferus petiolis duplo vel triplo brevior, 5—10 ecm. 
longus, levis; involucri folia 4, ovato-lanceolata, acuminata, sub- 
zequalia, exteriora 2—92,5 cm. longa, 0,7—0,8 cm. lata, 9—10-nervata; 
flores 3—5 in umbrella, petiolis brevibus (c. 1,0 cm. in statu fructifero) ; 
cirri longi numerosi; perianthium, stamina et stylus fere ut in 7. 
lanctfolia (Schnitzlein, 1. c.); fructus (submaturus) sicco-baccatus, 
2 em. longus, perianthio persistenti coronatus, 6-alatus; semina 
numerosissima, oblique ovata, curvata, striata, 0,25—0,30 cm. longa, 
0,15 em. lata. 
Dr. Schmidt has brought home 4 dried specimens and some um- 
bels in alcohol of a Yacca which is allied to T. lancifolia Zoll. & Mor. 
in Java, but differs by the shorter stalked leaves, the very short scape 
ete.; the umbels preserved in alcohol and the three dried specimens 
have not full-developed flowers, only young buds; but there is one 
specimen with nearly ripe fruit. The form of the leaves and of the 
involucral leaves are about as in a javanese specimen of T. lancifolia, 
and consequently | think it better to consider the Siamese plant a variety, 
until we know the entire-leaved species of Tacca better. It seems to me, 
that they form a line from T. cristata Jack, T. integrifolia Ker. Gawl., 
T. laevis Roxb. to T. lancifolia Zoll. & Mor., the length of the scape 
and the differentation of the involucral leaves varying very much; therefore 
other characters are necessary for distinction. 
The Indian plant figured by Schnitzlein (1. c.) from a specimen 
sent by Wallich belongs beyond doubt to T. lancifolia; 1 have also 
seen a specimen from Wallich’s herbarium which is like javanese T. lanei- 
folia, only being a little larger. 
Jungle near Klong Son, end of February (No. 641). 
Area (of P. lancifolia): Java, India (Wallich).
