196 FOUR NEW GENERA OF AROIDEiE. 



Species two, natives of Borneo. 



Allied to PiptoHpatha, of which it has the habit and general 

 appearance, but is at once distinguished b}^ the united ovaries and 

 different anthers. 



G. BuRBiDGEi, n. sp. — Petiole 4-5 inches long, terete, chan- 

 nelled down the face, dilated into a very short sheath at base ; 

 lamina cuneate-lanceolate acute, 9 inches long, l|-2 inches broad ; 

 midrib very prominent and rounded beneath, primary lateral veins 

 7-9 on each side of it. Peduncles longer than the petioles. 

 Spathe 1^-2 inches long, light rose-coloured. Spadix terete, the 

 male and stamodiferous portion thicker than the female part ; 

 ovaries pale greenish, anthers cream-coloured ? 



North West Borneo ; margins of rocky mountain rills, Bukit 

 Sagan, 500 feet, Burbidge ! 



Mr. Burbidge informs me that he also discovered a second 

 species of this genus about 100 miles farther north, fringing the 

 Dahombang and Kina Taki streams, near Kina Balu mountam ; he 

 unfortunately lost both the living plants and specimens of it. But 

 from the description Mr. Burbidge gave me of it, and from a 

 drawing of it with which he has kindly furnished me, it appears 

 to differ from the above described species in its larger size, 

 broader leaf, and much thicker spadix. 



Gearum, n. g. 



Spathe tube convolute, very oblique at the base, limb boat- 

 shajDed, acute, mucronate. Spadix moncecious, free, obliquely 

 sessile, exappendiculate, male and female portions closely con- 

 tiguous with an intermediate staminodiferous portion. Flowers 

 densely crowded. Ovaries intermixed with flattish obovate neuter 

 organs," subglobose or globose-trigonous, 3-4-celled, each cell with 

 one subbasilar, subsessile, erect, orthotropous ovule. Stigma sessile 

 or subsessile, 3-4 lobed. Male flowers nude, 4-(5 ? )-andi'ous, 

 stamens united in a very short sub-hexagonal truncate column ; 

 anther-cells short, elliptic-oblong, placed beneath the margin, 

 dehiscing by short apical slits. Eootstock tuberous. Leaf appearing 

 after the flowers, solitary ? pedate. Inflorescence solitary, peduncle 

 short. 



Species one, native of Brazil. 



G. BRAsiLiENSE, n. sp. [Tab. 231, fig. I.] — Flowers appearing 

 before the leaf. Peduncle 1-2^ inches long. Spathe white, 5-6 

 inches long, tube and limb subequal. Spadix shorter than the 

 spathe, the female part occupying one sixth of its length, terete, 

 male part fusiform. 



Brazil, on the plains in low-lying places that are often inun- 

 dated, between Sape and Santa Brizida, Province of Govaz. 

 Burchell, No. 8111 ! 



• The material being partly destroyed by insects, I am unable to say whether 

 these neuter organs (staminodia? perianth-segments? ) were merely intermixed 

 with the ovaries, or whether each ovnry was surrounded by a definite number of 

 them as in Dieffenhachia ; only two or three of them were found, although several 

 ovaries were examined, so probably they do not surround each ovary.
