SPATHIPHYLLUM 



4o 



Distribution : Limited to rainforests of eastern Oaxaea, Mexico. 



MEXICO: Oaxaea: Trapiehe de la Conception, Jul 1842, Liebmann s.n. (C) ; pr. Tona- 

 gui'a, Aug 1842, Liebmann s.n. (C) ; vicinity of Choapam, Jul 1894, Nelson 906 (US). 



8. brevirostre finds its closest ally in 8. atrovirens of Costa Rica. Found at 

 high elevations in the state of Oaxaea, it is known only from the original collec- 

 tions and a single subsequent one, all made in the previous century. 



8. brevirostre differs from 8. atrovirens by its more shortly decurrent spathe 

 and the narrower angle at which the primary lateral veins arise. It appears to be 

 allied to 8. matudae of adjacent Chiapas and Guatemala, but the longer style of 

 the pistil in this latter species serves to distinguish it from 8. brevirostre . 



33. S. blandum Schott, Oesterr. Bot. Woehenbl. 7: 159. 1857. Figure 8. 



Leaf-blade elliptic to oblong- or lanceolate-elliptic, 30-45(-65) cm long and 

 (8-) 11-19 (-25) cm wide, commonly widest at the middle and narrowed equally 

 toward either end, the apex and base acute-acuminate ; petiole shorter than the 

 blade, 27-37 (-45) cm long, often alate up to the geniculum, the wing apically 

 auriculate and 5-8 mm wide; geniculum 1.5-2.8 (-3.2) cm long. Peduncle com- 

 monly lYo-2 times as long as the petiole. 45-70 (-90) cm long; spathe typically 

 elliptic. 12-22 (-27) cm long and (3.6-)4.5-8(-9.8) cm wide, acuminate at each 

 end, or varying to oblong and sometimes oblanceolate with the apex cuspidate and 

 1.5-3 cm long, the base acute or obtuse and finally attenuate, decurrent on the 

 peduncle (often obliquely) 2-5.5(-8.5) cm ; spadix (3-) 4.5-11 (-14) cm long, ses- 

 sile or on a stipe l(-2) cm long; perianth of separate segments; pistil elongate- 

 conic, the exserted portion equaling or longer than the perianth; ovary (2-)3- 

 locular, the ovules collateral, varying from 3 to 1 in each of the 3 locules, totaling 

 8-4 ovules per ovary; fruiting spadix tuberculate, the fruit to 10.5 mm long, obo- 

 void, rostrate; seeds 7-3, oblique-reniform-ovoid to oblong in profile, their inner 

 faces flat and smooth, the outer face rounded, smooth to slightly verruculose 

 between the vertical rows of foveola. 



Type: the original description [Int. Code Bot. Nomencl. (1956) Art. 10. 

 note]. Schott described this species from a living plant in cultivation. Apparently 

 no type specimen was preserved. An excellent representative specimen of 8. 

 blandum is I). Smith 1534 (G, GH. US). 



Distribution: Widespread in wet situations along coast of the Gulf of Hon- 

 duras in British Honduras. Guatemala, and Honduras, extending deep into the 

 interior of Guatemala.
