Plan of the Manual 



The Manual intends to cover all seed plants definitely known from territory within the contemporary political 

 boundaries of Costa Rica, including Isla del Coco, Isla del Cafio, and all inshore islands. For more details con- 

 cerning format, see the chapter "Plan of the Manual" in Vol. I: Introduction. 



Within Gymnosperms, Monocotyledons & Dicotyledons (in that order), 

 families ("-aceae" terminations), genera and species are in alphabetical 

 order.

 for each genus.

Native species and naturalized

 well as exotic species grown 

 on a large scale.

Common names widely used in Costa Rica are indicated. 



Monospecific 

 families have only 

 one description 



(combined family, 

 genus, species). 

 Likewise, mono- 

 specific genera 

 have the genus 

 and species 

 descriptions 

 combined.

Habitat descriptions roughly follow the Holdridge Life-Zone System.

For every species treated formally, a voucher specimen collected in Costa Rica is cited. 



Length x width 



measurements are 

 always in that 

 format. If "length 

 (height)" or "width" 

 is not specified, the 

 former may be as- 

 sumed. An illustra- 

 tion of at least one 

 species is provided 

 for each native or 

 naturalized genus.

Herbaria are desig- 

 nated by acronyms 

 according to Index 

 herbariorum. 



Distributional data are in this order: Habitat, elevational 

 range within Costa Rica; geographic range within 

 Costa Rica. Flowering phenology in Costa Rica. 

 Overall geographic range. 



Each family, genus, and species description is followed by a brief 

 discussion. The principal agenda of these discussions is to provide a 

 "diagnostic shortcut" for recognizing the taxon involved.
