Nat. On». XXXII. CRASSULACEA, DC. 
Gen. I. TILLZEA, Mich. (including Bulliarda, DC.) 
Sepala, petala, et stamina 3-5. Sguama ad basin carpellorum 3-5 v. 0. Ovaria 3—5; stylis bre- 
vibus recurvis; ovulis plurimis. Carpella 3-5, membranacea, intus dehiscentia. Semina, pauca v. plurima. 
Very small, succulent plants, with opposite leaves, and axillary, solitary, or fasciculate flowers. Sepals, petals, and 
stamens three to five. Scales as many, opposite the ovaries, or 0. Ovaries with short recurved styles, one-celled, 
many-ovuled. Carpels few- or many-seeded.—The few species belonging to this inconspicuous genus are inhabitants 
of damp or dry places, and are scattered over various parts of the globe, chiefly in temperate latitudes. One of the 
Southern species belongs to Bulliarda of DC., a genus differing only in the more highly-developed glands or scales 
opposite the ovaries, which I do not think affords of itself a character of generic importance. (Named in honour of 
Michael Angelo Tilli, an Italian botanist of Pisa.) 
1. Tillea verticillaris, DC.; erecta, simplex v. e basi ramosissima, foliis oppositis lineari-oblongis,

t. 295.) A. Cunn. Prodr. T. muscosa, Forst. Prodr. A. Rich. Flora. 
Haz. Northern and Middle Islands; dry rocky places; abundant, Forster, Colenso, ete. 
Whole plant a pale red-brown colour. Stems succulent, 2-4 inches high, simple or branched from the base. 
Leaves linear-oblong, 1-2 lines long, succulent, blunt. Flowers very densely crowded in the axils of the leaves, very 
minute, mostly sessile, a few pedicellate; pedicels slender, longer than the leaves. Sepals four, ovato-subulate, 
acuminate. Ovaries without glands or scales. Carpels one-seeded.— Very like the European T. muscosa, but usually 
larger in all its parts, with tetramerous larger flowers, and narrower sepals. It is also a Cape of Good Hope plant. 
2. Tillea debilis, Col.; caule repente laxe ceespitoso distanter folioso, foliis oppositis connatis brevi- 
oblongis linearibusve obtusis, floribus solitariis v. 9 axillaribus sessilibus pedunculatisve 4-meris, sepalis 
oblongis acutis, petalis brevioribus ovatis acuminatis, glandulis 0, carpellis 1-2-spermis. 
Has. Northern Island. Hast coast, Colenso. 
Stems 2-3 inches long, weak, slender, simple or sparingly branched. Leaves opposite, in remote pairs, 1-2 lines 
long, connate, ovate-oblong or linear. Flowers few, one to two, sessile or peduncled, very minute. Sepals four, 
ovate, acute, longer than the ovate acuminate petals. Glands none.  Carpels four, one- to two-seeded. —I am 
doubtful how far this is really distinct from T. verticillaris, which it closely resembles. 
3. Tillea purpurata, Hook. fil. ; perpusilla, caulibus e basi decumbente ramosa erectis prostratisve, foliis 
oppositis connatis linearibus, floribus breve v. longe pedicellatis 4-meris, sepalis ovatis obtusis v. subacutis, 
petalis parvis acuminatis, glandulis 0, carpellis 4 magnis obtusis recurvis apice hiante bilobo, seminibus 
plurimis. Nob. in Lond. Journ. Bot. v. 6. p. 472. An T. peduncularis, Sm., DC. Prodr. ? 
Has. Northern Island ; east coast, Cape Palliser, etc., Colenso. 
A very minute, purplish plant. Stems prostrate, 4-3 inch long, rarely longer. Leaves as in the other species. 
Flowers few, in the axils of the leaves, sometimes nearly sessile, but often on pedicels longer than the stem. Sepals 
four, blunt. Petals as many, very short, sharp. Glands none. Carpels longer than the sepals, blunt, recurved, 
many-seeded, the top when burst two-lobed. Seeds many.—A very distinct species, but so minute as to require a 
strong lens to make out its characters. It is a native of Tasmania.
