Pothos.] OLxvi. ABOiDE^. (J. D. Hooker.) 553 



Ceylon, Walker. 



Stum and foliage as in the common state of P. soandens and Vriesianus. 

 Fedunele often longer than the petiole. Spathe |-| in. Spadix i-i in., its stipes 

 about as long. 



6. P. macrocephalus, Scort. mas. ; leaves lanceolate apiculate, 

 petiole as long as the blade, peduncle li-2 in. decuryed, spathe ovate- 

 cordate or orbicular cuspidate, spadix globose or shortly pyriform. 



Febae, fScortecJiim, King's Collector. 



(Jlimbing 60-80 ft. j branches as thick as a crow-quill, internodes J— J in. 

 Leaves 2^-3^ by J-f in. ; rather broader than the petiole. Peduncle rather stout ; 

 bracts very variable, sometimes few with the longest only J in., at others many, and 

 ^in. long. Spathe i-^ in. diam., white; occasionally a second smaller superior spathe 

 occurs. Spadix ^ in. dlam., or less, yellow. — This differs from P. Jimghimamis 

 and maerophyllus, de Vriese (in Plant. Jungh . i. 103, 104) of Java and Sumatra 

 solely in the narrower leaves and great length of the petiole. I suspect that all 

 there may prove forms df one. 



B. Petiole (knee only) very short ; sheatb very long, split to the base. 

 Spadix long, sessile or stipitate. 



* Spadisa cylindric, dense-fld. ; flowers not in clusters. 



7. P. King"!!, Hook. f. ; stout, leaves 6-10 by 3-4 in. oblong or oblong- 

 lanceolate caadate-acuminate, base narrowed rounded, bracts 1^-2 in., 

 spathe 4-6 in. ovate-lanceolate. 



Peeak ; ScortecMni, King's Collector ; alt. 2-3000 ft. 



Stem 6-10 ft., as thick as a swan's quill, branches 2-3 ft., pale. Leaves coria- 

 ceous, often unequal-sided, shining on both surfaces ; petiole i in. j sheath 3-4 in., 

 margins membranous, at length fibrous, tip 2-anricled. Spathe dark purple within, 

 pale without. Spadix half as long. Ovarg oblong j style very short, stigma 

 penicillate. 



8. B. Barberianus, Schott Aroid. 24, t. 53 ; Prodr. 573 ; leaves 3-5 

 bv l^lj in. oblong- or ovate-lanceolate acuminate base rounded, sheath 

 clasping the branch, peduncles terminal and axillary, spathe linear- 

 lanceolate. Engler Arae. 90. 



Pebak ; on rocks, ScortecMni, King's Collector. — Disthib. Borneo, 



Stem slender, branches as thick as a crow-quill. Leaves thinly coriaceous, tip 



sometimes caudate; petiole ^ in., sheath 2-3 in., by ^-i in. broad, biauricled. 



Peduncle defiexed, l-H i". Spathe J-1 in., acuminate. Spadix as long, sessile. 



Stigmas pulvinate, sessile. 



9. P. Wallichii, Hook. f. ; leaves 3^-4 in. oblong-lanceolate acumi- 

 nate, base cuneate or rounded, sheath divergent from the branch, peduncles 

 axillary and terminal, spathe linear-lanceolate acuminate. P. tenera, 

 Wall. Oat. 4439, B. (not Wall, in Boxb. Fl. Ind. Ed. Carey). P. gracilis, 

 Schott Prod/r. 572. Engler Arac. 91 (not of Boxb.) 



Pknang, Porter, Curtis ; Peeae:, Scortechini. 



Very similar to P. Barberianus in foliage, but a more slender plant, with the 

 spreading leaf-sheaths not i in. broad, the peduncle 1^-3 in. long much more slender, 

 a shortly stipitate spadix, and a slender minute style with a very inconspicuous 

 stigma.— In Carey's Edition of Roxburgh's Flora Indica, Wallich proposed the name 

 of P. tenera for an Amboyna plant cultivated in the Calcutta Garden, named P. 

 gracilis by Roxburgh in mss.
