This, like Calandrinia, is almost wholly an American genus, and one species is a very Arctic one. The only
Austraban species known to me is the present, whicb also grows in New Zealand.— Ofteu succulent, herbaceous,
annual or perennial plants, with alternate or opposite leaves, and axillaiy, peduncled flowers or racemes. Calyx
two-lobed to the base. Corolla o f five, membranous, generaUy white petals, often united at the base. Stamens
five, united each to the daw o f a petal. O ta ry one-ceUed, with an erect style, trifid at the top, the divisions papUlose
on the inner surface. Omles numerous, situated near the base o f the cavity, amphitropous. Seeds three or
more, attached to long, free funicuU, with farinaceous albumen, and a curved, cyUndiical embiyo. (Named in honour
o f John Clayton, an English botanist and traveUer in North America.)

Extremely variable in size and habit, according to the moisture, etc., of the locality it inhabits.— A smaU,
tufted plant, 1 inch high in drier places ; a very long, straggling herb, a foot long, in water. Stems prostrate, rooting.
Leaves 4 - 5 inches long, very long, linear, strap-shaped ; petioles with a dilated, membranous vagina at the
base. Floioers on axiUary, slender peduncles. Sepah orbicular, concave, one-quarter as long as the petals, but
variable in proportionate size. P e tah obovate-oblong or spathulate, very membranous, white, extremely variable in

A smaU, tufted, water or marsh plant, found in many quarters o f the globe, and only distinguished from Claytonia
by tbe sepals being sometimes three, and the seeds fewer than three.— Stems often attaining 6 -8 inches in
water. Leaves spathulate or narrow linear-spathulate, succulent, 4 - 1 inch long. Flowers white, small, in soUtary,
axUlary, rather thick, curved or straight peduncles.— The apparent rarity of this plant in Tasmania is remarkable,
for it is usuaUy of very frequent occurrence in the countries it inhabits. (Named in honour of Joseph de Monti, a

The number (8 or 10) o f Australian Crassulacea is-much smaller than m igh t have been expected, conside
ring how analogous the chmate aud so il o f mauy parts o f th a t continent are to those o f Sou th Africa,
where th ey abound. The absence o f auy succulent vegetation {Aloe, Euphorbia, Sbapelia, Cactus, Mesembryanthemum,
aud Crassula) in the desert o f Australia is a very remarkable feature, and in this respect it
contrasts with other' dry climates. W h a t Crassulacea there are, almost all be lon g to the widely diffused
g en u s T illa a , which is also European.

There are probably five or six species of this genus in Australia, but they have not been closely examined :
some are very similar to South African and South American ones. I have considered the speeies of P ulliarda as
members of the genus, difl'ering only in the presence of stipitate glands, of very variable size, at the bases of tbe
ovaries. Small, generally minute, succulent, opposite-leaved plants, with axillary, solitary or fascicled, inconspicuous
flowers. • Sepah, p e ta h , stamens, and carpeh three to five, the latter with short, reemved styles, and few or
many seeds. (Named in honom o f Michael Angelo Tilli, a botanist o f Pisa.)
