Sumatra: “Hochangkola-Tobing”’ (leg. JuNGnvuN anno? 1839. — 
Plantae Junghuhnianae ineditae n. 542 in Herb. Lugd. Batav.). 
The species described above is the third representative of the genus 
Polyporandra Bece, belonging to the /cacinaceae and related to 
Jodes Bl. This species, Polyporandra Junghuhnii, was found by me 
in 1908 in ’sRijks Herbarium at Leiden (Plantae Junghuhnianae 
ineditae N°. 542) and had been collected by JuncHuun in the Battak 
country at “Hochangkola-Tobing”. It differs 4. a. from the two 
already known species of Polyporandra in the structure of the 
calyx; in PP, scandens Brccart (in Malesia I (1877) 125 tab. 7) 
and P. Hansemanni ENGrer (in ENererR Botan. Jahrb. XVI, Beiblatt, 
N°. 39 (1893) 13) the calyx is cup-shaped and has short teeth, 
whereas in Polyporandra Junghuhnu it is 5-partite, with pointed 
segments 1 millim. long. 
Superficially the flowers of Polyporandra Junghuhnit somewhat 
resemble these of Natsiatwin herpeticum Bucuan, but our Polyporandra 
is sharply differentiated from their species by the characteristic struc- 
ture of the anthers, described above. 
That our species must be included in the above-mentioned genus 
Polyporandra Bree, seems to me to be highly probable. Since however, 
all the material, which has as yet been found, consists of a single 
dried branch with young, not completely developed male flowers, 
floral bud and three leaves, I consider it possible that afterwards, 
when the as yet unknown female flower, fruits and seeds of Poly- 
porandra Junghuhnii shall have been found, this species will prove 
to be the type of a new sub-genus of Polyporandra or of a new
