LXV. COMPOSITE. 19h 



10. LAGENOPHORA, Cass. 



(Aohenes flagon-shaped.) 

 (Ixauohenus, Cass.; Solenogyne, Coss.; Bmphysopus, Hook.f.) 

 Involucre nearly hemispherical, the bracts in about 2 rows, nearly equal, broad 

 or narrow, with dry or scarious margins. Receptacle convex, without scales. 

 Florets of the ray numerous, female, ligulate or short and tubular. Disk-florets 

 numerous, hermaphrodite, tubular, with a more or less dilated limb, 5-toothed. 

 Anthers obtuse at the base. Style-branches in the disk-florets somewhat flattened, 

 but long and slender, papillose outside at least in the upper portion. Aohenes 

 compressed, abruptly contracted at the top either very shortly or into a distinct 

 neck. Pappus none. — Small perennial herbs, with a tufted stock, radical leaves 

 and leafless simple scapes, or rarely the scapes growing out into simple stems 

 decumbent and leafy at the base. ' Flower-heads terminal, the ray white or 

 purplish. 



A small genus, chiefly Australian, but extending also to New Zealand and many parts of 

 tropical Asia. Of the 3 Queensland species, one appears to be the same as the Asiatic one, the 

 other two are endemic. 



Eay-florets ligulate, linear, longer than the involucre and spreading. Plower- 

 heads without the ray not above 4 lines diameter. Involuoral bracts 



narrow I. L. Billardieri. 



Eay-florets not exceeding those of the disk. 



Scapes slender, mostly much longer than the leaves. Bay-florets all 



tubular, 3-toothed 2. L. Solenogyne. 



Scapes thickened, shorter or rarely longer than the leaves. Eay-florets 

 minute, mostly opening out into a short concave lieula 3; L. Emphysopus. 



1. Ii, Billardieri (after J. J. Labillardiere), Cass., DC. Prod. v. 307 ; Benth. 

 Fl. Austr. iii. 507. A perennial with a short thick stock and slender creeping 

 rhizomes, otherwise stemless with radical leaves and scapes, or the stems shortly 

 decumbent and leafy at the base. Leaves from obovate to cuneate-oblong, obtuse, 

 irregularly toothed or shortly lobed, narrowed into a petiole, usually all under 2in. 

 long, rarely above Sin. Scapes slender, simple, from 2 or Sin. to nearly 1ft. long. 

 Involucre from under 3 to nearly 4 lines diameter, the bracts rather numerous, 

 linear or oblong, acute or rather obtuse. Eay-florets blue, ligulate, exceeding the 

 involucre. Achenes at least as long as the involucre, the margins usually glan- 

 dular-pubescent, contracted at the base and abruptly contracted at the top into a 

 neck sometimes as long as the breadth of the achene, sometimes very short. — 

 Hook. f. Fl. Tasm. i. 188 ; Bellis stipitata, Labill. PI. Nov. Holl. ii. 55 t. 205 ; 

 Ixauohenus subLyratus, Cass.; DO. Prod. v. 308; Brachycome pumila, Walp. Rep. 

 ii. 584, according to Steetz in PI. Preiss. i. 428 ; LarjenojjJiora gracilis, Steetz in 

 PI. Preiss. i. 431. 



Hab.: Brisbane Elver, Moreton Bay, and other southern localities. 



The species is also in Ceylon, Khasya, the Indian Archipelago, and S. China. There are 

 generally two distinguishable varieties :— 1. microcepluda, glabrous or hirsute, the flower-heads 

 without the rays scarcely 3 lines diameter and the rays short, the most common tropical and 

 subtropical form, and, 2. normalis, usually hirsute, the flower-heads without the rays about 4 

 lines diameter and the rays rather longer ; this is most abundant in the southern districts. 

 LabiUardifere's own specimens are almost intermediate between the two. — Benth. 



2. Ii. Solenogyne (old generic name), F. v. M. Fragin, v. 62 ; Benth. Fl. 

 Austr. iii. 508. Glabrous or hirsute. Radical leaves from obovate to oblong- 

 cuneate, obtuse, 1 to 2in. long, toothed at the end or above the middle, narrowed 

 into a distinct petiole. Scapes filiform, much longer than the leaves, usually 

 with a few distant small narrow-linear leaves. Flower-heads scarcely above 2 

 lines diameter when in flower, nearly 3 lines when in fruit. Involuoral bracts 

 oblong, obtuse, with scarious often denticulate or cili ate margins. Eay-florets 

 numerous, all apparently erect, tubular, and 8-toothed, notHonger than the disk.
