GLOSSARY OF 



Involute: rollf.l inward from both edpes (Fig. 93). 

 Rkvoi.ute: rolled backward from both edpcs (Fig. 9-4). 

 CiROiXATE : coiled from the apex, as in Ferns (Fig. 95). 

 Equitaxt : each leaf doubled lengthwise and astride of the 

 next loaf within, as in Iris (Fig. 96). 



INFLORESCENCE. 



Arr inffemeut of the Floicers or Floicer-clustersonthestem. 



Mode. 



TjuotlNAh : when the separate liowers are on the ends of 

 stems or branches. 



Terminal Inflorescence is al.so known as Determinate, 

 or Definite, or Cvmose, or Centrifugal, and it is 



(a) Solitarif : when a single flower terminates the 

 stem, as in Tulip and Hepatica. In other words the 

 flowers do not form a cluster (Fig. 97). 



(b) A Cifine : when the flowers are in a cluster of 

 which the central flower (on the end of the main stem) is 

 the earliest (Fig. 98), as in Chickweed and Sweet-William. 

 In Chickweed the cjTne is loose, and in Swoot-William it 

 is dense. 



(Special cases of Cymes arising from the axils of leaves 

 are referred to below under the head of Mixed Inflores- 

 cence. ) 

 Axillary : when the separate flowers spring from the axils 

 of leaves or bracts. 



Axillary Inflorescence is also known as L.xteual or 

 Indeterminate, or Indefinite, or Racemose, or Botkv- 

 osE, or Centripetal; and it is 



(a) Solitary : when the flowers are jiroduced singly- in 

 the axil.s of ordinarj' leaves (not bracts), as in Morning- 

 Glory. etc. The flowers do not form a cluster. 



(b) A liacf^ie : when the flowers form a rather long 

 cluster, each flower being in the axil of a bract, and hav- 

 ing a pedicel (little stalk) of its own (Fig. 99). 



(In plants of the Cress familj' the bracts are absent.) 



(c) A Spikr : when the 8c])arafe flowers are .sessile, or 

 nr.'iiK' so, .'ilotiL' flif- in.'iin :ixi.s, as in TTi ill\ Ik x-k , »-tc. 



1 _ . ■ 



(d) .1 Ifpiul : when the axis of the cluster is .short, and 

 the tiowers coi ly rather closely packed together, 

 as in Clover ana 1 1. -rle, etc. 



,.. , l.i T'l.ii^i: wlien the pedicels of the flowers are of 

 thf I, and arise from the same ix)int (Fig. 101). 



(f) A Corymb : when the pedicels arise from different 

 points on the .ntem, but the flowers reach the same level 

 above (Fig. 102).
