342 INDIGENOUS 



Indigenous, genuinely native. 



Indigo, Indigofera\ China green-, Rhamnus chlorophora Decne. ; 

 Chinese -, Polygonum tinctorium Ait. 



Indigofera L. Leguminosae (in. 6). 300 trop. /. kptostachya DC., 

 tinctoria L. and Anil L. furnisli indigo. The plant is mown just 

 before flowering, and soaked in water, whereby a yellowish solution 

 is obtained. This on stirring and exposure to the air oxidises, and 

 an insoluble precipitate of indigo is formed. The fls. are slightly 

 explosive (cf. Genista). 



Indokingia Hemsl. Araliaceae (i). i Seychelles. 



Indomalaya, cf. Floral Regions, it (6) and (7). 



Indovethia Boerlage. Ochnaceae (Violaceae BH.}. i Borneo. 



Induplicate (aestivation), leaf margins turned inwards; (vernation), 

 Palmae. 



Indusium, Filicales, Pteridophyta. 



Inermis (Lat.), unarmed, thornless. 



Inferae (BH.}. The ist series of Gamopetalae. 



Inferior (ovary), enclosed in the receptacle. 



luflexed, bent inwards. 



Inflorescence, the reproductive shoot, composed of, or bearing, a number 

 of shoots of limited growth, termed flowers. Of two types, mono- 

 podial or racemose, where the first axis does not as a rule terminate 

 in a fl., but grows steadily onwards; and sympodial or cymose, 

 where the main axis soon terminates in a fl., and the growth is taken 

 up by the lat. axes in succession. The typical raceme has an axis 

 growing indefinitely up the middle, and successively younger fls. on 

 lat. branches, Cruciferae, Primus, Ribes. There are also the cpd. 

 raceme or panicle, the raceme with sessile fls. or spike, with its var. 

 the catkin or pendulous spike, the corymb, or raceme with all the fl. 

 stalks elongating to the same level, Iberis, the umbel, which may be 

 imagined as a corymb with all the fls. springing from one point, 

 Umbelliferae, the cpd. umbel, the head, which is a common re- 

 ceptacle with the fls. arranged in a dense mass with the youngest to 

 the centre, Compositae, the cpd. head. The cyme may be mono-, 

 di- or pleiochasial, according as each branch bears upon itself r, 2 or 

 more branches; cf. dichasial cymes, &c. Many pi. possess mixed 

 infls., with some branchings racemose, some cymose, Aesciilus, Be- 

 tulaceae, Labiatae, Verbascum. 



Infundibuliform, funnel-shaped.
