202 ERICACEAE. [Azalea. 



ing. Leaves, when first appearing, covered with long rusty hairs, which soon 

 disappear, except on the petioles ; when full-grown, ovate, seldom above 1 in. 

 long, dark green and smooth above, glaucous, with a network of rust-coloured 

 veins underneath. Mowers on very short pedicels, issuing singly from long 

 cylindrical scaly buds, more or less covered with rusty-brown hairs. Calyx- 

 teeth very short and hairy. Corolla obliquely campanulate, as in A. indica, 

 but smaller, and usually of a pale colour. Stamens 8 to 10. 



Common on the hill-tops, Champion, and others. Not known from elsewhere. 



Order LXIY. PEIMULACEiE. 



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

 shortly adherent to the ovary. Corolla regular, more or less divided into as 

 many lobes or teeth as divisions of the calyx, or rarely wanting. Stamens as 

 many as lobes of the corolla, inserted in the tube opposite the lobes. Ovary 

 1 -celled, with 1 or more ovules attached to or immersed in a free central pla- 

 centa, which is often thick and globular. Style single, with a capitate stigma. 

 Fruit a capsule, and usually dehiscent. Seeds albuminous. — Herbs or rarely 

 undershrubs. Leaves alternate, simple, entire or toothed, without stipules. 

 Flowers axillary or terminal. 



A widely spread Order, inhabiting chiefly the northern hemisphere, and especially high 

 mountains, often at great elevations. A few species reappear in the Antarctic regions, and 

 but very few within the tropics. 



1. LYSIMACHIA, Linn. 



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

 Stamens 5. Capsule opening in 5 or 10 valves. Perennials, with erect or 

 trailing stems, and opposite or whorled, rarely alternate or tufted leaves. 

 Flowers usually yellow, solitary, on axillary pedicels, or collected in terminal 

 or rarely axillary racemes or clusters. 



A considerable genus, having a wide range in the northern hemisphere. 



1. L. alpestris, Champ, in Kew Journ. Bot. iv. 299. Stock perennial, 

 short, but emitting occasionally runners of 1 to 3 in. Leaves tufted on the 

 stock or at the ends of the runners, narrow-oblong, spathulate, or sometimes 

 almost obovate, 1 to 2 in. long, obtuse, entire, nan-owed at the base into a 

 short petiole, stiffly hairy on both sides. Peduncles 1-flowered, axillary, and 

 about as long as the leaves. Sepals oblong, acuminate, 2 lines long. Corolla 

 rotate, yellow, 8 or 9 lines diameter, divided almost to the base into 5 obo- 

 vate-oblong minutely fringed lobes. Filaments united in a cup at the base. 

 Anthers oblong. Capsule globular, shorter than the calyx, 5-valved. Seeds 

 numerous. 



In subalpine situations, Champion j always on the banks of streams, Eyre ; on the top of 

 Victoria Peak, Wilford ; also Wright. Not known from elsewhere. 



Order (or Suborder) LXV. MYRSINACE-E2. 



Flowers of Primulacem, usually pentamerous or tetramerous. Fruit an in- 

 dehiscent berry or drupe, or very rarely splitting lengthwise on one side. Seed 8
