(few in Tillaea). Fruit of several 1-celled follicles, dehiscing along tne 
ventral suture. Seed few or many, minute, albuminous ; embryo terete, 
cotyledons short. 
A rather large family, spread over the whole world except Polynesia. Particularly 
abundant in South Africa, where nearly half the species are found ; _also plentiful in 
the rocky districts of Europe and central Asia; rare in Australia and South America. 
Genera about 15; species estimated at 450. All the species are inert, and are of 
little importance from an economic point of view. The single New Zealand genus is 
almost-cosmopolitan.

Smalfand slender somewhat succulent glabrous herbs. Leaves opposite, 
entire. Flowers minute, axillary, solitary or fascicled, sometimes cymose. 
Calyx 3-5-lobed or -partite. Petals 3-5, free or connate at the base.. 
Stamens the same number as the petals. Hypogynous scales 1 to each 
carpel or wanting. Carpels 3-5, narrowed into short styles; ovules | or 
more to each carpel. follicles few- or many-seeded. 
An almost cosmopolitan genus, comprising about 25 species. Two of those found 
in New Zealand also occur in Australia, and another in temperate South America, the 
Falkland Islands, and Kerguelen Island. Several of the New Zealand species are 
imperfectly known, and require careful study with recent specimens before satisfactory 
diagnoses can be prepared. 
Schonland, in Engler and Prantl’s ‘‘ Pflanzenfamilien,’’ reduces Tillaea, together 
with some other genera, to a section of Crassula. But this course has not received 
general acceptance; and as Tvllaea undeniably constitutes a distinct group, and is 
retained as such by nearly all writers, and as there are no true Crassulae in the New 
Zealand Flora, it appears undesirable to make any change.
