Calyx tubular or campanulate, 4-lobed. Corolla tubidar at the base, 3- 

 lipped, the upper lip concave or hood-shaped, with 2 broad spreading lobes ; 

 the lower lip spreading, 3-lobed, overlapping the upper ones in die bud. 

 Stamens 4 in pairs ; anthers 3-celled, connivent under the upper lip of the 

 corolla, the cells mucronate, often hairy. Style slightly dilated at the end. 

 the stignui obtuse, entire or with a small upper lobe. Capsule oblong, com- 

 pressed, opening loculicidally in 3 valves. Seeds oblong, striate.— Herbs 

 either annual or perennial and branching at the base, believed to be often 

 partially parasitical on roots. Leaves opposite, toothed or lobed. Flowers 

 sessile or nearly so in short and dense or long and interrupted terminal spikes, 

 the floral leaves or bracts usually more acute than the stem-leaves. Bracte- 

 oles none. Anther-cells equal in all the Australian species, unequal in some 

 others. 



The genus comprises a small number of very variable species distributed over the tempe- 

 rate and colder regions of the northern hemisphere, extralvopical South America and ISew 

 Zealand. Of the ei^ht Australian forms here admitted as species, one is also m JNew Zea- 

 land and l-'uegia, another is very near a New Zealand one, and tlie remainder appear to be 

 endemic, but some of them are scarcely more than marked varieties.
