eonglutinate in age; pistil white, obpyraniidal, apically truncate, the stigma 

 elevated and shortly exceeding the perianth; ovary 3-locular, the ovules affixed 

 at or near the base of the locules, varying from (3-) 2 to 1 in each of the 3 locules, 

 totaling (7—) 6-4 ovules per ovary; fruiting spadix smooth; fruit spheroid, the 

 apex truncate; seeds 1 or 2 per locule, the surface vertically furrowed and foveo- 

 late between the verrucose ridges. 



Type: pi. 159, L 'Illustration Horticole 21: 24. 1874. This color plate ade- 

 quately defines 8. floribundum, and agrees with the original description which it 

 accompanies. This species was described from a plant growing in cultivation, 

 and no type material appears to have been prepared. A fine representative 

 specimen of 8. floribundum is Lehmann 7758 (F, Oil, US), which is more or 

 less identical to the material cultivated today under this name. 



Distribution : Banks of streams in the central Magdalena Valley of Colombia.

Perhaps the most handsome member of the genus, this species has been a 

 popular conservatory subject for nearly a century. Though not described until 

 1874, 8. floribundum was first collected by Gustav Wallis before 1864. The 

 original description gave no data on its arrival in Europe, but stated only that it 

 was prepared from a plant growing in the garden of M. Linden for the previous 

 two years, and that its publication had been delayed by lack of sufficient flowers 

 to determine in which genus it should be placed (they erroneously selected 

 Anthurium!). In 1875 (Hamb. Gart. Blum. 31: 63), AVallis listed .4. floribundum 

 among his collections near San Carlos (Aguas Claras), Xew Granada, mentioning 

 that many of these same sj)eeies were collected previously. It is likely that 8. 

 floribundum was first collected in that locality. 



S. floribundum appears to be endemic to the Magdalena Valley of Colombia. 

 Various authors have referred to this species collections from Panama, but I 

 cannot corroborate their identifications. Vegetatively Bailey 209 resembles this 

 species, but a cursory inspection of the spadix clearly demonstrates the conic 

 pistils; it is referred to 8. phryniifolium. Standley (Ann. Missouri Bot. Gard. 

 31: 34. 1944) cited this collection as 8. floribundum. then illustrated the species 

 with a drawing of Seibert 507, which I identify as S. quindiuense. 



There seems little cause to maintain var. eu neat urn of this species. It was 

 based upon Lehmann 2592, collected in Tolima. Colombia. That specimen was 

 deposited at Berlin, and was probably burned. 



8. floribundum is outstanding for its dark green leaves with a velvety lustre. 

 As a dried specimen, however, it differs in its broad leaves. It is most closely re- 

 lated to 8. fulvovirens and 8. ju nine use, both of which are species of much greater 

 size than this species. 



Some cultivated material of 8. floribundum lias the spathe cuspidate at the
