apex, in contrast to the long-attenuate apex of the spathe in all collections from 

 the wild. This difference of the cultivated form may have resulted from selection 

 by horticulturists. 



15. S. fulvovirens Schott, Oesterr. Bot. Zeitschr. 8: 179. 1858. Figure 7. 

 Leaf-blade oblique, typically ovate to ovate-elliptic, (25^)35-44 cm long- and 



(10-) 17-20 cm wide, the apex terminated by a cusp 1.5-3.5 cm long, the base ob- 

 tuse to subrotund, the many primary lateral veins arising- at an angle of 60-70° 

 and very prominent beneath ; petiole to 74 cm long, alate in the basal two-thirds ; 

 geniculum (1-) 1.5-3 cm long. Peduncle to 49 cm or more long; spathe d= oblong 

 and clasping at the base; spadix 6.8-11.5 cm long, smooth, on a short stipe 0.3-0.8 

 cm long-; perianth of separate segments; pistil obpyramidal, apically truncate, 

 the nipple-like stigma scarcely exceeding' the perianth ; ovary 3-loeular, the 

 ovules affixed near the base of the locules, 2 or 1 in each of the 3 locules, totaling 

 6-5 ovules per ovary ; fruit unknown. 



Type collection: H. von Wedel 2198, lt shrub 3 ft., inflorescence gray. Fish 

 Creek, vicinity of Chiriqui Lagoon," Prov. Bocas del Toro, Panama, 9 Apr 1941 

 (neotype Gil, duplicates F, MO). The designation of a neotype is appropriate 

 since neither the holotype {Wendland 939, "Pedregal, C. Rica, 1857") nor any 

 duplicate of it has been located. A photograph of the hoknwpe (Field Mus. no. 

 29838) clearly indicates that the type was deposited at Vienna, and therefore we 

 must assume that it was burned along with the other Araceae. 



Distribution: [Pedregal( ?), Costa Rica], along Chiriqui Lagoon in northern 

 Panama, in the centra] Magdalena Valley and Pacific coast of Colombia (Buena- 

 ventura). 



COLOMBIA: Rio Magdalena, Weir S5 (BM). Santander: Amarilla Creek, vicinity of 

 Barranca Bermaja, Magdalena Valley, between Sogamoso R. & Carare R., Jul 1936, Eaught 

 1895 (F, US), Valle del Cauca: Rio Dagua, Buenaventura, Lfhmann 5361a (F, K). 



CULT. : "coll. Fl. Claes, Colombia, Juin 1927," V. Lambert .v. n. (BR). 



A good photograph of the holotype in conjunction with the original descrip- 

 tion of 8. fulvovirens serves to define this species very well. It is further clari- 

 fied by an original Schott drawing (W). 



The exact collection locality of Wendland 939 is uncertain. Standley (Field 

 Mus. Publ. Bot. 18: 48. 1937) noted that Wendland entered Costa Rica* " by the 

 Sarapiqui Valley, and explored especially the mountain chain from Barba 

 to Turrialba," which would limit his localities to the provinces of Heredia and 

 Cartago, on the Atlantic slope of the Cordillera. 



The Colombian collections referred to this species have a somewhat narrower 

 leaf-blade than is typical, but they are essentially similar in other features. 



8. fulvovirens finds its nearest relative in 8. juninense, a Peruvian species with 

 a wider spathe. These two might well be considered as infraspecific categories of a 

 single species, but are maintained here as separate species because of the great 

 distance between their areas of collection and the natural barrier to continuity 

 of distribution created by the Cordillera Oriental of the Andes in Colombia. 



16. S. juninense Krause, Xotizbl. Bot. Gard. Berl. 11: 615. 1932. Figure 6. 

 Leaf-blade oblique, ovate-elliptic, 28-32 cm long and 12-15.5 cm wide, the 



apex cuspidate (probably; lost from type specimen), the base rotund-obtuse, 

 with many primary lateral veins arising at an angle of ca. 55-60° ; petiole 40-57 

 cm long, alate throughout much of its length ; geniculum 1.6-2 cm long. Peduncle 

 to 70 cm long ; spathe oblong, to 19 cm long and 5.7 cm wide, the apex long-cuspi- 

 date, the base apparently obtuse; spadix to 12.3 cm long, on a stipe ca. 1.5 cm 

 long; perianth of separate segments; pistil obpyramidal, 1 the apex subtruncate,
