Amazonas" and illustrated in the latter 's publication. 20 The fruit-cupules, except 

 for the proximity of the two margins, strongly resemble those of Martius' illus- 

 tration. This characteristic of the cupules has not always proved reliable, how- 

 ever. A close examination of more mature fruits of Williams 11686 shows that 

 the outer rim of some cupules has been broken, giving the appearance of greater 

 proximity of the two margins. Possibly the Nectandra cymbarum of Martins' 

 illustration represents a different phase of development under a variant situa- 

 tion. Certainly the leaves and branchlets show no significant differences. The 

 vernacular name "Sasafras" appears on the Fernandez label, but no mention 

 is made of the uses of the tree. Possibly Martius' plant may represent the fruiting 

 stage of N. urophylla Meissner, based on Spruce 222, (Ned. 2) (fl.) collected at 

 Santarem. Subsequent collections may shed light on this rather baffling problem.

Nectandra salicifolia Nees, Linnaea 21: 506. 1848 (ex parte, non Syst. Laurin; syntype, 



SchomburgTc 858, isotype, fl. NY). 

 Nectandra salicifolia var. p Nees, Linnaea 21: 507. 1848; isotype, Hostmann 973, st. NY). 



Vernacular Name. Shirua (Brit. Guiana). 



Distribution. Shrub or small tree of British Guiana and Suriname extending 

 into the Rio Carom area of Bolivar, Venezuela, south to the border between 

 Brazil and Venezuela up to 750 m. VENEZUELA. Bolivar : selvas de Guairam- 

 pai, Lasser 1374 (fl. NY, US) ; occasional at woodland edge near Fazenda Natal, 

 10-12 km northeast of Fazenda Vista Geral, frontier between Territorio do Rio 

 Branco, Brazil and Estado Bolivar, Cerro do Sol, Maguire & Maguire 40248 

 (y. fr. NY). BRITISH GUIANA. From part secondary Maximiliana marsh 

 forest, Powis Creek, Courantyne River, For. Dept. British Guiana 5399 (Field 

 No. 2611) (fl., fr. NY). 



Of the paratypes cited by Meissner, the following only were available : Schom- 

 burgk 549 (fl. NY), from Roraima, British Guiana, and Hostmann & Kappler 

 579 (st. NY). The numbers I have cited agree with the paratypes and with the 

 only syntype available for study at present. 



Superficially, this species has the aspect of N. cymbarum, but the leaves differ 

 in the type of venation ; the much smaller flowers bear very broad anthers without 

 attenuated connectives; and the smaller fruits are subtended by cupules more 

 typical of the genus Nectandra as it has generally been recognized.
