 Camp Via, 3100 ft. (In flower, January.) 



This species differs from G .microcarpum, Scbeff., in having only 2 or 3 stout short spikes 

 on the spadix, in the sepals of the male flowers being very narrow and almost separate 

 to the base, and in the coriaceous lanceolate point of the petals in the female being 

 much narrower and TBore acute, whilst the thinner widely dilate base is much larger in 

 pi'oportion. The male flowers in this plant open apparently long before the females, 

 which are very small at that time. When they fall they apj)ear to leave no separate 

 scar, and the female flowers develop so as to fill uj) the spadix so closely that the 

 spadix in female flowers appears to be completely unisexual. The rhachis of the leaf 

 has an elevated ridge running down the middle on the upper surface. 



The genus includes four species, two from Ceram and two from New Guinea. 



LiNOSPADix MiCHOLiTZii, Bidl. in Gard. Chron. 1895, ii. 202. 



Camp I, 500 ft. ; and Camp VI «, 3100 ft. 



The original plants of this species were stemless, with entire obcuneate leaves bifid 

 only at the apex. In one of Kloss's specimens there is a portion of a stem 1 cm. in 

 diameter with smooth internodes 4 cni. long, the nodes having rather a broad annulus 

 where the leaf has fallen. The leaves are also cut into two pairs of leaflets in addition
