 PHASEOLUS, Einn. 

 (Erom^^ose^Ms, a little boat; the supposed reaembiance in the pods.) 

 Upper teetli of calyx free or connate, the others deltoid or 

 lanceolate. Standard orbicular, recurved or subtwisting, the edges 

 mllexed towards the base ; wings obovate, or rarely oblong, equalling 

 or exceeding the standard, adhering to the teel above the claw, often 

 twisted J keel hnear or obovate, with a long obtuse spirally- twisted 

 beak. Upper stamen free, often incrassated or appendiculate above 

 the base, the rest connate; anthers uniform. Ovary subsessile, 

 multiovulate ; style incrassated within the beak of the keel, "and 

 twisted with it, usually longitudinally bearded upwards; stigma 

 oblique. Pod linear or falcate, terete or compressed, 2-valved, thinly 

 septa,te between the seeds. Usually climbing herbs with pinnately 

 trifojiolate leaves. 



P. VUlgrariS, Linn. The Common Erench Bean. Stems annual, 

 wide-climbing, sub-glabrous. Leaflets 3, the central one broad-ovate, 

 4 to 5 inches long, acute, both sides sub-glabrous. PeduncleB in 

 pairs, 1 to 2 inches long, 2 or 3-fiowered. Pedicles 2 to 4 lines ; 

 Dfacteoles oyate. Calyx campanulate, i-inch deep, upper lip truncate, 

 lower S-toothed. Corolla white or lilac, an inch deep. Pod 4 of 6 

 inches long, i-inch feroad, nearly straight, cpmpresaed, glabrous, 10 to

Order MYRTACEiE. 



An important order, especially from an Australian point of view, 

 as it includes much of our timber and fruits, as well as aromatic oils, 

 spices, and dyes. The number of species are about 1,80G; genera 

 about 80. 



Calyx-tube adnate to the ovary at the base or up to the insertion 

 of the stamens ; limb more or less divided (usually to the base) into 4 

 or 5, very rarely 3 or more than 5, lobes or teeth, or reduced to a 

 narrow border, or entirely wanting ; lobes usually imbricate or open 

 in the bud ; petals usually as many as calyx-lobes very much imbricate 

 in the bud, the external one somietimes larger than the others, biit 

 usually all nearly equal when expanded, sometimes all concrete and 

 falling off in a single operculum, or rarely entirely wanting. Stamens 

 indefinite, usually numerous, or rarely few and definite, inserted in 1 or 

 several rows on a disk, either thin and lining the calyx-tube above the 

 ovary and forming a thickened ring at its orifice, or thicker and forming 

 a ping close round the sunimit of the ovary ; filaments free or rarely 

 united into a ring or tube at the base, or into as many b.undles as there 

 are calyx-lobes ; anthers 2-eelled, versatile or attached by the base, 

 the cells opening in longitudinal slits, or rarely in terminal pores. 

 Ovary inferior or rarely almost superior, -but enclosed in the calyx- 

 tube, sometimes 1-celled, with a placenta attached to the base OT 

 adnate to one side, more frequently 2 or more celled, with the 

 placentas in the inner angle of each cell, very rarely l-celled, with 2 

 parietal placentas. Style simple, with a small or a capitate or peltate, 

 very rare! JF, lobed, stigma. Ovules 2 or more to each placenta in 2 or 

 more rows, or very rarely solitary, erect pendulous or laterally 

 attached, anatropous or amphitropous. Eruit inferior, adnate to the
