dex valde abbreviatus, circiter 2 cm. crassus. Folia 
membranacea, atroviridia irregulariter albido-maculata, 
lanceolato-linguiformia, utrinque glabra, apice acutissima 
cum apiculo flexuoso, 13-17 mm. longo, basi inaequaliter 
rotundata, in petiolo 5-9 cm. longo, basi purpureo- et 
roseo-maculato, ad vaginam latiusculo, 7-80 mm. longo 
producta; lamina 11-15 cm. longa, 2.5—-4 em. lata; ner- 
vis lateralibus angulo acuto adscendentibus. Pedunculus 
crassus, usque ad 20-22 cm. longus sed vulgo brevior, in 
vagina foliacea saepe inclusus, apicem versus, 2 mm. in 
diametro, Spatha aperta lanceolato-elliptica, longe acu- 
minata, usque ad 9 cm. longa, 1.5—1.8 cm. lata, utrinque 
viridia, Spadix cylindricus, apicem versus tenuior, stipi- 
tate robusto, brevi, minute albo-granuloso, 4mm. longo, 
4—5 mm. in diametro suffultus. Staminum filamenta late 
linearia, 0.5 mm. longa, antherae minutissimae. Pistilla 
1 mm. longa, vertice tetragono stigmate coronata. 
The long and flexuous apicules on the leaves of this 
new species seem to set it apart from other concepts of 
Stenospermatium. Stenospermatium verecundum would 
appear to be nearest to S. Ulei, at least vegetatively, but 
the former has a much shorter and stouter peduncle than 
the latter species. 
Stenospermatium verecundum is apparently endemic to 
the quartzitic mountains of Amazonian Colombia, where 
it grows in white sandy savannahs, under conditions of 
extreme xerophytism. It is often associated in the field 
with the lichen Cladonia, as illustrated in the accompa- 
nying photograph (Plate X XII). 
The specific name, meaning ‘‘modest,’’ refers to its 
inconspicuous habit of growth.
