than the rest with simple (not feathery) tips ; those of the outer achenes often 

 fewer, subpaleaceous, free at the base, simple or feathery below. — Biennial or 

 perennial milky herbs. Leaves alternate, stem-clasping, narrow, quite entire. 

 Heads terminal, long-peduncled, large homogamous, yellow, blue or purple. 

 Florets all ligulate. 

 Plants of Europe, K. Africa, temperate and subtropical Asia. 



1. T. porrifolium (Leek-leaved), Linn. Salsify. A glabrous biennial or 

 perennial of 1 to 2ft. with a taproot. Ea^ioal and lower leaves long and grass- 

 like, entire, shortly dilated and sheathing at the base, the upper ones shorter and 

 broader. Peduncles long, thickened at the summit, each with a single head of 

 purple florets. Involucre of 8 to 12 nearly equal bracts, longer than the florets. 

 Achenes murioate, narrowed into a long beak, bearing a pappus of feathery 

 bristles. 



Hab.: Darling Downs ; abundant along the railway between Toowoomba and Warwick. An 

 European species. 



Oeder LXVI. STYLIDIEiE. 



Calyx-tube adnate to the ovary, the limb of 5 divisions, all free or less united 

 in 2 lips, the upper one consisting of 3, the lower of 2. Corolla usually 

 irregular, deeply divided into 5 lobes, of which one (the lowest), called the 

 labellum, much smaller or very different from the others, or rarely the corolla as 

 well as the calyx regularly 5 or 6-lobed. Stamens 2, the filaments connate with 

 the style in a column from the corolla ; anthers sessile at the top of the column, 

 2-celled, the cells at length divaricate. Style or stigma terminal, entire or 

 2-lobed, concealed between the anthers or protruding from them. Ovary 

 2-celled or 1-celled except quite at the base, 'with many ovules attached to the 

 centre of the dissepiment, surmounted frequently by 1 or 2 glands at the base of 

 the style. Capsule opening from the top downwards in 2 valves parallel to the 

 dissepiment. Seeds numerous or rarely solitary by abortion, very small, with a 

 minute embryo in a fleshy albumen. — Herbs or rarely undershrubs. Leaves 

 radical or scattered or collected in whorl-like tufts. Flowers hermaphrodite or 

 very rarely unisexual, in terminal racemes or thrysoid or corymbose panicles, 

 rarely reduced to spikes or to single flowers, the primary inflorescence usually 

 centripetal, the secondary often or sometimes the whole inflorescence centrifugal. 



A small Order, chiefly Australian, a very few species being found in tropical Asia, or in New 

 Zealand and Antartic America. The Order is very nearly allied to Campanulacea, and some 

 species have quite the habit of some Lobelias, but they constantly differ in the close union of the 

 filaments with the style. — Benth. 



1. STYLIDIUM, Swartz. 



(From stylos, a column ; the filaments and style connate in a column.) 



(Porsteropsis, Sond.) 



Calyx-lobes 5, often more or less united in 2 lips. Corolla irregular, 1 of the 



lobes or labellum much smaller and turned down or rarely nearly as long and 



curved upwards, the other 4 ascending in pairs. Column elongated and bent 



down or folded, elastic in most of the species if not in all. Stigma undivided. 



Ovary 2-celled — Habit and foliage those of the Order. Flowers in racemes, 



panicles or corymbose cymes on terminal peduncles or radical scapes. 



A genus comprising nearly the whole Order, and almost entirely Australian. The majority of 

 the species form a rosette or spreading tuft of radical leaves, from the midst of which springs the 

 scape. Sometimes the following year the new leaves and scapes are close upon the old ones, 

 forming a dense tufted stock, the bases of the leaves sometimes assuming a bulbous appear- 

 ance ; in others, one or two short stems are formed above the old tuft, each crowned by a new
