Mantisia Sims. Zingiberaceae (i). 2 Indomal. M. saltatoria Sims 



(dancing girls) often cult, for its curious fls. , borne on separate shoots 



from the rhiz. At the base is the K, then 3 broad pets., a curiously 



shaped labellum and 2 filamentous stds., and beyond all the fertile 



sta. and style.

 Marainophylium Pohl. Inc. sed. Nomen. 

 Maranta Plum, ex L. Marantaceae. 18 trop. Am. The stds. /3 7 



(see fam.) are present in many. The rhiz. of M. arimdinacea L. 



furnishes West Indian arrowroot, prepared by grinding and washing 



to free the starch. 

 Marantaceae (EP. ; Scitamineae p.p. BH^]. Monocots (Scitamineae). 



12 gen., 150 sp. trop., chiefly Am. Herbaceous perennials of various 



habit, resembling Zingiberaceae, but at once distinguishable by the 



presence of a swollen pulvinus or joint at the junction of petiole and 



leaf-blade. L. 2-ranked, sheathing; one side of the 1. is larger than 



the other and is covered by it when the 1. is rolled up in the bud. Fls. 



usu. upon the leafy shoots, in pairs in the 



axils of the bracts, either one pair or many 



(cymose, drepania). The fi. is asymmetric, 



but in each pair the one is complementary 



to the other (i.e. like its reflection in a glass). 



Fl. g , pentacyclic, 3-merous. P 3 + 3, 



clearly distinguished in most cases into calyx 



and corolla. As in the allied fains., the 



A is united to the C. There is one fertile 



sta., often petaloid, and round it various 



petaloid structures (cf. carefully Canna 



and Zingiberaceae). The labellum of 



Canna is represented by a hood-shaped 1. 



covering the style (Kapuzenblatt). The 



staminode a is repres. by a more or less 



leathery or callous 1. (Schwielenblatt) ; /3 



and 7 are not always present, but are petaloid 



when they do occur. The same views as to 



the morphology of these structures have been proposed as in the case
