ANATOMY OF NONCOSTAL PORTIONS OF 



LAMINA IN THE CYCLANTHACEAE 

 (MONOCOTYLEDONEAE). V. TABLES OF DATA 



George J. Wilder* 



This is the last paper of a series which pertains to lamina 

 anatomy in the Cyclanthaceae (Wilder, in press a, b, c, d). Each 

 paper is based on the same fifty-three species and ten genera of 

 the family. Collection localities have been listed (Tomlinson and 

 Wilder, 1984). The present paper includes tables which document 

 findings in all previous papers of the series. Tables are organized 

 into four groups representing paper nos. I-IV of the series, 

 respectively. Each group of tables is introduced by a synopsis of 

 the paper which it represents. 



INTRODUCTION TO TABLES 1-6 



(Wilder, in press a) 



The outer walls of ordinary epidermal cells exhibit inner non- 

 cutinized and outer cutinized regions, and are covered by a 

 cuticle sensu stricto (Table 1). Noncostal portions of cyclan- 

 thaceous laminae are always hypostomatic, i.e., having the 

 majority of stomata situated in the abaxial epidermis (Tables 2, 

 3). In noncostal parts of this epidermis, stomata are oriented 

 within stomatal bands, and such bands are separated by inter- 

 stomatal bands of four main kinds: (/) in interridge areas, bands 

 located over superficially situated fiber strands of the mesophyll, 

 (2) also in interridge areas, bands situated over the largest longi- 

 tudinal veins, (J) bands occurring on abaxial ridges, and (4) 

 bands of epidermal expansion tissue. Given a small strip of 

 epidermis, it is sometimes possible to ascertain the following: 

 whether it is adaxial or abaxial; if abaxial, whether portions 

 thereof are from interridge areas, ridges, or expansion tissue, and
