2. PLATYTHECA, Steetz. 



Stamens in 2 distinct series, the anthers continuous with the fih^ment ; with 

 4 parallel cells in a single plane, contracted into a tube at the top. I^isk 

 none. Capsule opening locidicidally at the edge, with the valves splitting, 

 septicidally. Seeds glabrous, without appendage. — A heath-like shrub, with 

 verticillate leaves. 



1. P. galioides, Steetz, in PL Preiss. I 220. An erect heath-like shnib 

 or undershrub, with slender terete branches, sometimes quite glabrous, but 

 more frequently with a little tuft of Iiairs at each node, and often pubescent 

 below the nodes. Leaves usually about 8 in a whorl, narrow- linear, some- 

 times very acute and pungent, sometimes almost obtuse or with slightly re- 

 curved points, about ^ in. long, with the margins often revolute so as to be 

 almost terete or 3-angled, glabrous or rough, with a few scattered short rigid 

 hairs. Pedicels slender, | to 1 in. long. Sepals narrow-lanceolate, acute, 3 

 to 4 lines long. Petals nearly ^ in., blue with a dark spot at the base. An- 

 thers short and broad, with long slender tubes. Ovary glabrous, with 2 su- 

 perposed ovules in each cell. Capsule about 3 lines long. — -P. crucianella, 

 Steetz, 1. e. 221 ; P. crassifolia, Steetz, 1. c, 222 ; Tetratheca verticillata, Paxt.

3. TREMANDRA, R. Br. 



Stameus apparently in a single series, the anthers articulate on the short 

 filiform filaments, 2-celled, not attenuated into a tube, although openir.g by a 

 single terminal pore in 2 short valves. Di^k crenate, almost 5-lobed, between 

 the petals and stamens. Capsule opening at the edges. Seeds with an ap- 

 pendage or stvophiola at the chalazal end. — Shrubs with stellate hairs or 

 tomentum. Leaves opposite, toothed. 



Densely tomentose. Leaves 1 in. or more. Pedicels shorter than the 



leaves 1, T. stelUgera. 



Slender, with minute scattered stellate hairs. Leaves nnder | in. Pe- 

 dicels longer, filiform 2, T. diffusa. 



1. T. steUigera, R. Br. in DC. Prod, i. 344. A shrub of 2 ft. or 

 more, densely clothed with stellate hairs sometimes short and tomentose or 

 aliuost floccose, sometimes loug and hirsute. Leaves opposite, shortly petio- 

 latc, ovate, obtuse, 1 to 1^ iu. loug, coarsely and irregidarly toothed or rarely 

 entire. Pedicels shorter tliau the leaves. Sepals lanceolate, tomentose or 

 villous, 2 to 3 lines long. Petals but little lou-er. Anthers rather longer 

 than their filaments, dark-purple, hirsute pubescent or glabrous, truncate 

 or oblique at the top. Ovary densely pubescent, with 2 superposed ovules m 

 each cell. ^ Capsule brondly ovate, pubescent. Seeds more or less silky-pu- 

 bescent, with a large hooked appendage at the chalazal end. — T. oppositljoUay 

 Steetz, in Pi. Preiss. i. 222.
