GENUS V. 
MACLEAYA, R. Br. THE MACLEAYA. 
Lin. Syst. POLYANDRIA MONOGYNIA. 
Generic Character. — Sepals 2, caducous. Petals none. Stamens | placentas. Seeds fixed to parietal placentas. Albumen fleshy. 
24 — 28. Stigmas 2, spreading. Capsule elliptical, with many-seeded I Embryo very minute, erect. (G. Don.) 
Description, &c. — There is only one species in this genus, which was separated from Bocconia, and named 
in honour of Alexander MacLeay, Colonial Secretary in New South Wales. 
1.— MACLEAYA CORDATA, R. Br. 
Synonyms. — Bocconia cordata, Willd. 
Engravings. — Bot. Mag. t. 1905 ; and out fig. 7 in Plate 15. 
THE CORDATE-LEAVED MACLEAYA. 
I Specific Character. — Leaves roundish, cordate, obsoletely lobed, 
1 glaucous on the under surface. Flowers disposed in large panicles. 
Description, &c. — This species is said to be " a very ornamental, stately, herbaceous plant, when grown in 
a rich soil." It is a native of China, whence it was introduced in 1795. It flowers in June and July, and it is 
propagated by dividing the roots in spring. This plant is not suitable for a small garden, as it grows from three 
to five feet high, and spreads proportionately. 
CHAPTER VI. 
FUMARIACE.^. 
Character of the Order. — Sepals 2. Petals 4, the outer two or 
one of them saccate at the base ; inner two callous, and coloured at the 
apex, where they unite, inclosing the anthers and the stigma. Stamens 
6, in two parcels, or rarely separate. Anthers some l.celled, others 
2-ceUed. Ovary superior, 1-celled ; ovules horizontal ; style filiform ; 
stigma with two or more lobes. Fruit various. Seeds horizontal, 
shining, crested. 
Description, &c. — The plants belonging to this order are easily known by the very singular shape of their 
flowers. They difiier from Papaveracece, to which they are nearly allied, in their juice being watery, aiid their 
petals irregular. The word Fumaria, which gives its name to the order, is derived from Fumus, smoke, 
alluding to the smell of the British plants included in the genus Fumaria. 
GENUS I. 
DIELYTRA, Borck. THE DIELYTRA. 
Lin. St/St. DIADELPHIA HEXANDRIA. 
Generic Character. — Petals 4, the outer two equally spurred or I two bundles, or joined at the top, and free at the base. Capsules 
gibbous at the base. Stamens 6, altogether free, or approximating into I 2-valved, many-seeded. (G. Don.) 
Description, &c. — The species included in this order are all perennial plants, which were formerly included 
in the genus Fumaria, and afterwards in that of Corydalis. The name of Dielytra is from dis, double, and 
elytron, a sheath, alluding to the two sheath-like spurs at the base of the flower. The flowers of the species are 
produced in racemes, and are yellowish or pinkish, and the roots are generally tuberous. The leaves nearly all 
spring from the root, and they are generally on long stalks, and much cut. The species are all quite hardy, and 
of very easy culture, being easily increased either by dividing the root, or by seeds. _ .
