twice to three times as long as wide, thus differing from those of S. cochleari- 

 spathum, which are more or less oblong, widest at the middle, and proportionally 

 narrower than the blades of 8. matudae. 



This species has the common name "huisnay" (or some variation of it) 

 throughout its range. Collectors report that the natives eat the spadices either 

 cooked with eggs, or cooked and pickled in vinegar. In the narrative of his 

 travels, Preuss (Exped. Zentr. Sudani. 123: 1901) noted this practice. Preuss' 

 specimen, cited by Engler as 8. ortgiesii, appears to be no longer extant. It was 

 collected at San Andres-Osuna, northwest of the city of Eseuintla, Guatemala. 

 Undoubtedly, his specimen was conspecific with 8. matudae rather than with 

 8. ortgiesii. Engler and Krause (Pflanzenreich 4 23B : 122. 1908) cited J. D. Smith 

 1625 (Santa Rosa, Guatemala) as 8. friedrichsthalii. I have not seen it, but its 

 locality suggests that it also may represent 8. matudai . 



27. S. grandifolium Engl. Bot. Jahrb. 37: 119. 1905. Figure 5. 



Leaf-blade oblique, ovate-oblong, 47 cm long and 24 em wide, the apex acumi- 

 nate-cuspidate, the base obtuse-rotund, the many pairs of primary lateral veins 

 arising at an angle of 60-70° (-80°) ; petiole 54 cm long, alate below, the 

 geniculum 2 cm long. Peduncle* equaling the petiole; spathe elliptic-oblong, 20 

 cm long and 5 cm wide, the apex attenuate, the base cuneate and decurrent on 

 the peduncle 3.2 cm; spadix* 15 em long, on a stipe 1 cm long; perianth* of sep- 

 arate segments; pistil* rostellate but scarcely exserted above the perianth, lo- 

 cuies* of the ovary 4-ovulate; fruit unknown. 



Type collection: F. C. Lehmann 563, "auf dem Boden in dichten Regenwal- 

 dern bei Altaquer an den Westabhangen das Cordilleren von Pasto, 1000 m.," 

 Naririo, Colombia, Mar 1881 (holotype B). Unicate, presumably. Known only 

 from the type collection. 



8. grandifolium is closely related to 8. atrovirc ns of Costa Rica, but its spathe 

 is more shortly decurrent than in the latter species. 



28. S. wallisii Regel, Gartenflora 26: 323. pi 920. 1877. 



Leaf -blade lanceolate- to oblong-elliptic (14—) 24-36 cm long and (3-) 5-10 

 cm wide, marginally undulate, the apex long-acuminate, recurved at the tip, the 

 base acute, the midrib nude in the lowermost 2 cm above the geniculum, the 

 primary lateral veins ca. 8-10 pairs arising at an angle of 45-50° ; petiole sub- 

 equaling the blade or a little longer, to 45 cm long, commonly alate in the lower 

 part or nearly to the geniculum ; geniculum 1.4-2.3 cm long. Peduncle longer 

 than the petiole, ca. 20-64 cm long; spathe cucullate, ovate to oblong-elliptic, 7-17 

 cm long and 2.5-7.5 cm wide, the apex long-acuminate [to 2.5 cm], the base 

 commonly obtuse or subrotund, sometimes acute, decurrent on the peduncle 1.5-4 

 cm or more, white, becoming green in age; spadix fragrant, 1.5—8 cm long, on a 

 stipe 0.5-1.2 cm long; perianth white, of separate segments; pistil ± elliptic in 

 outline, the style conic, white, prominently exserted beyond the perianth ; ovary 

 3-locular, with 4-3 (-2) ovules ± fascicled in each of the 3 loeules, totaling 12-6 

 ovules per ovary; fruit unknown. 



Type: the original description. 8. wallisii was described from a plant growing 

 in cultivation (in Europe) ; apparently no type specimen was preserved [Int. 

 Code Bot. Nomencl. (1956) Art. 10, note]. Known only in cultivation. 



CULT.: in big pot, Hotel Francis, Oaxaca de Juarez, Mexico, Mar 1940, Bailey 550 (BH) ; 

 F. Sander & Co., 22 Feb 1898, Brown s.n. (K) ; Kew Gardens, 17 Oct 1912, Harvey 608/1911, 

 Brown s.n. (K) ; 6 Apr 1914, Thompson 10 (MO) ; Garfield Park Cons., 3 Aug 1939 (F) ; etc. 



8. wallisii was reportedly introduced from Colombia, but this has not been
