Order LXIX. PHIMULACE^. 



w 



Calyx usually of 5, sometimes 4, 6 or 7 divisions or teeth, free or rarely 

 the tube shortly adnate to the ovary. Corolla regular, more or less divided 

 into as many lobes or teeth as divisions of the calyx, imbricate and often con- 

 torted in the bud, rarely wanting. Stamens as many as lobes of the corolla, 

 inserted in the tube or at the base, opposite the lobes. Ovary 1-celled, with 

 1 or more ovules attached to or immersed in a central placenta, usually quite 

 free, thick and globular, rarely ovoid aud connected with the top of the ca- 

 vity. Style single, with a capitate stigma. Fruit a capsule, usually de- 

 hiscent. Seeds albuminous. — Herbs or very rarely undershrubs. Leaves 

 opposite or alternate, undivided except when growing under water, without 

 stipules. Flowers axillary or terminal. 



^ A widely-spread Order, inhabiting chieflv the northern hemisphere, and often P^ing m 

 high mountains to great elevations, with a few southern species, and but very few witfam tne 

 tropics, except in mountain districts. The three Australian genera are all widely spreaa 

 over the area of the Order. Myrsinece, which generally replace Primtdacem in the warmer 

 regions of the globe, scarcely differ from them, except in their shrubby or arboreous habit. 

 Calyx entirely free. No stamiuodia. 



Capsule opening in 5 or 10 valves or irregularly dehiscent. Corolla 



rotate or campanulate. Leaves whorled opposite or alternate . . 1- LysimacHIa. 

 Capsule circumsciss. Corolla rotate or campanulate. Leaves oppo- 

 site or alternate 2. AnaGaLLTS. 



Calyx partially adnate. Stamiuodia or scales alternating with the lobes 

 of the corolla ..... . . 3. Samol^ts. 



1. LYSIMACHIA, Linn. 



Calyx free, deeply B-cleft. Corolla rotate or campanulate, deeply 5-lobetl. 

 Stamens 5. Capsule opening in 5 or 10 valves or rarely bursting ureguiariY. 

 Placenta globular.— Perennials, with erect or procumbent stems. Leaves op- 

 posite or rarely whorled or scattered, or in species not Australian, alternate ^^ 

 tufted. Flowers yellow or (in a few species not Australian) white, solitar}, 

 on axillary pedicels or in terminal racemes. 



A considerable genus, having a wide range in the northern hemisphere, but limitej in Jbe 

 southern hemisphere to the two Australian species, one of which is endemic, the oiuei 

 same as a widely dispersed Asiatic one.
