TO LOWER SIAM. 123 



G. pseudochina, var. .. . 



A tall plant with the stem, leaf on both sides and 

 involucral bracts, covered with pale scabried hairs. Bracts 

 green, flowers rich yellow, 2£ feet tall, achenes glabrous, 

 Pappus white, Bangtaphanoi on the beach (Keith). 



This plant has a tall stem, leafy throughout, and has 

 much the habit of G. bicolor. It closely resembles the 

 common Malay plant which I take to be G. pseudochina 

 but is hairy with thin hairs all over. The common plant 

 is nearly glabrous. It differs from the typical G. pseudo- 

 china in its tall leafy stem and non-tuberous roots. These 

 Gynuras have been very much confused. The numbers 

 quoted under G. bicolor Dec. in the Materials belong to 

 two quite distinct plants, and neither resembles the figure 

 of Cacalia bicolor Bot. Keg. 110.
