VII. PAPAVERACE^E. 63 



without stipules. Fluwers usually solitary on long peduncles, either terminal 

 or in ihe upper axils. 



The Order belongs almost entirely to the temperate or subtropical regions of the northern 

 liemisphere, cue only genus being represented by a single species in the southern hemisphere ; 

 out, besides the Fapaver rhmas mentioned below, one at least of the numerous forms of the 

 i^uropean Fumaria offichmlis has established itself as a \ycea of cultivation in some parts of 

 Victoria and S. Australia, as in S. Africa. 



1. PAP AVER, Linn. 



Sepals 2, rarely 3, Petals 4, rarely G. Stamens indefinite. Placentas of 

 the ovary 4 or more, covered with ovides and projecting more or less into 

 the cavity, rarely meeting in the centre ; stigmas radiating on the convex 

 or almost conical disk-like summit of the ovary. Capside opening in trans- 

 verse pores between the placentas under the disk, with veiy short opercular 

 valves. Seeds furrowed. — Herbs, with a milky juice. Leaves usually lobcd 

 or cut. Peduncles long, the buds nodding. 



l-xcept the following one, the species are all from the northern hemisplicrc in the Old 



1. P. horridum, DC. Syd. Veg. i. 79. An erect annual, beset with su- 

 bulate prickles or stiif bristles, but otherwise glabrous and usually glaucous. 

 Leaves narrow-oblong or lanceolate, irregularly pinnatifid and coarsely toothed, 

 the radical ones coutracted into a petiole, the stem ones sessile or partially 

 stem-clasping. Flowers small for the genus, of a pale bxick or red colour. 

 «cpals hispid. Petals nearly ovate, about A in. long. Capsule ovoid-oblong, 

 perfectly smooth and glabrous, the terminal disk at first pyramickil, at length 

 |i^arly flat, usually- with 6, 7, or 8 stigmatic rays. Placentas as many, pro- 

 jecting lu the cavity but not meeting in the centre.— P. MueU. PI. Vict. i. 29 ;

wif'^'u^'T' T.inn., the common European Corn-Poppy, distinguished by its large red flowers 



^'th broad overlapping petals, and a nearly globular or turbinate smooth capsde with about 



" ^t'gmatie rays, has established itself in a few places in Victoria as an introduced weed. 



Order Ylir. CRUCIFER^. 



T'lowcrs hermaphrodite, regidai-, or with the outer petals larger. Sepals 4, 

 "•ee, imbricate in 2 scries, the outer ones often saccate at the base, 1 etals 

 V ^■^'■'•'ly wanting, the lamiuae spreading in the form of a cross; tonis usually 

 bearing 4 glands opposite the sepals. Stamens usually 6, of which 3 outer o,u;s 

 ;ijrter or rai'ely wanting, 4 inner ones longer, in pairs alternatmg witli the 

 ^uter ones. Anthers 2-ccUcd, attached by tlie base. Ovarj' 1-celkd with 

 ''parietal placentas or rarely a single one, or more frequently divided into 

 '^'^ cells by a thin membranous septum connecting the two parietal placentas.
