1920] Ridley : Peninsular Siamese Plants. 123 



I take this to be Beccari's canina. There is a leaf ot 

 it collected in Tenasserim by Heifer, labelled P. patnla, Bl. 

 by Hooker, but I do not think it is that species.

 Distrih. Malay Peninsula. A fruiting specimen only.

 6 to 9 in. long. " Flowers white." Flowers rf'mote, pedicels 

 •1 in. long, slender. Bracts minute, lanceolate. Calyx 

 tubular, narrowed at base dilate slightly upwards with three 

 very short points • 12 in. Petals wide, spreading lanceolate 

 acuminate, -12 in. long. Stamens 6, filaments lanceolate- 

 acuminate, red when dry. Anthers linear, oblong yellow.

Koh Jam Noi, near Koh Jam Yai off Takuapa : Flowers

This species approaches L. peltata of India from which 

 it differs in its smaller pedicelled flowers and much cut up 

 leaves. 



337. Calamus myrianthus, Becc.

 greenish yellow ; centres dark greenish brown ; 6554.

ARACEAE. 



340. Alocasia denudata, Miq. 



Koh Gall : Base of inflorescence white, remainder pale 

 buff ; stems mottled ; 6953. Distrih. Malay Peninsula, 

 Borneo. 



The form is the very hastate one with long narrow 

 lobes. 



341. Aglaonema Helferi, Hook. fil. 



This is allied to A. ohlongifolium but smaller in all 

 parts. The specimen is however, rather larger than the 

 type.
