288 GERANIACEAE 



schizocarp, the cpls. splitting off from a central beak (the persistent 

 style); each takes with it a strip of the tissue of the style, forming an 

 awn, which is usu. hygroscopic (cf. Geranium, Erodium). Embryo 

 straight or folded, in endosp Chief genera : Geranium, Erodium, 

 Pelargonium, Sarcocaulon. [BH. chars. Herbs with alt. or opp. 1. 

 Fl. 5, reg. or ! . Recept. hardly disc-like, often with 5 glands alt. 

 to C. K 5 or less, C 5 or less, or o, imbr., rarely conv. ; A twice as 

 many as K, often connate, G (3 5, rarely i), multiloc.; ovules 

 i 2 per loc., pend. or not, raphe various. Caps., schizocarp, or rarely 

 berry. Enclosp. little or o.] 



Geraniales. The 23rd order (Engler) of LHcots. (Archichl.). The 

 7th cohort (BH.) of Polypetalae. 



Geranium (Tourn.) L. Geraniaceae. 200 cosmop., esp. temp. (12 in 

 Brit., incl. G. pratense L., meadow cranesbill, and G. Robertiatuim L., 

 herb Robert). Infl. cymose, either dich. with cincinnus-tendency 

 (by preference of the /3-bracteole), or a cincinnus alone, which is 

 straightened out into a sympodium. The nectaries are at the base of 

 the sta. These stand at first round the undeveloped style ; after 

 dehiscence they move away, and finally the stigmas open. The 

 fr. explodes, the awn twisting up so that the cpls. are carried up and 

 outwards. In many sp. they open at the same time and the seeds-are 

 shot out. The G. of greenhouses is really a Pelargonium.

 whorled or alt., entire or toothed, never divided, exstip. Some are 

 root-climbers, and amongst these are a few epiphytes, e.g. Aeschy- 

 nanthus, usu. with fleshy water-storing 1. Many are tuberous, e.g. 

 the Sinningia (Gloxinia) of greenhouses. A number repr. veg. by 

 means of curious runners or suckers, covered with scale-leaves, usu.
