8TERCULIA FOETIDA Linn. Kalumpang. 
Local names: Baiigar (Ilocano, Itneg) ; bobog, bo-bog, bubog, bobo (Ba- 
labac, Iloilo, Negros, Palawan, Panay) ; boiigog (Cagayan) ; bubur, bobor 
(Ilocos Sur) ; kalumpang (Apo Island, Bataan, Camarines, Cotabato, Iloilo, 
Laguna, Manila, Mindoro, Nueva Ecija, Palawan, Pampanga, Polillo, Rizal, 
Tayabas) . 
A large tree with palmately five-foliate leaves, the leaflets 
oblong-lanceolate, acuminate, entire, glabrous ; flowers very 
fetid; capsules very large, bright red when mature, obovoid, 
splitting down one side, the oblong edible seeds persistent for 
some time after maturity; common and widely distributed in 
the Philippines. 
With the exception of two other basts, StercuHa foetida is 
the weakest fiber tested. Immersion in water for twenty-four 
hours does not affect its tensile strength. The extremely low
