4. SAROTHRA L. 
Firm-fleshy herbs, with erect branched stems and more or less black-dotted foliage. 
Leaves reduced to erect or appressed scales; these very short or somewhat elongated but 
destitute of blades. Flowers scattered along the branchlets, forming open or irregular 
cymes. Sepals 5, equal or nearly so, short or elongated. Petals 5, nearly equal. Sta- 
mens 5-20, shorter than the petals. Glands none. Ovary 1-celled, sessile. Styles 3, dis- 
tinct. Ovules several or numerous on the parietal placentae. Capsule more or less elon- 
gated, 1-celled, as long as the appressed sepals or much longer. Seeds ribbed or striate 
and pitted. 
Flowers sessile or nearly so: sepals much shorter than the conic capsules, 1. S. gentianoides. 
Flowers pedicelled : sepals and ovoid or oval-ovoid capsules about equal in length. 2. S. Drummondii. 
1. Sarothra gentianoides L. Annual, somewhat fleshy, but rather rigid. Stems 
1-5 dm. tall, often bushy-branched, or rarely simple, the branches wire-like, mostly 
opposite, sometimes filiform: leaves scale-like, appressed, often subulate or those on the 
lower part of the stem sometimes linear or narrowly-oblong: flowers scattered along the 
branches, sessile or nearly so: sepals linear or linear-lanceolate, 2-3 mm. long, acute or 
acuminate: corolla yellow, 4-8 mm. broad : stamens 5-10: capsules conic, 4-5 mm. long, 
much surpassing the sepals. [Hypericum Sarothra Michx.]

. 2. Sarothra Drummóndii Grev. & Hook. Annual, rigid. Stems 1-6 dm. tall, 
simple or bushy-branched, strongly wing-angled, the branches alternate : leaves scale-like, 
narrowly linear or linear-subulate, erect or strongly ascending, l-ribbed: cymes elon- 
ted : flowers scattered along the upper parts of the branches, pedicelled : sepals linear- 
anceolate, 3-4 mm. long, strongly nerved or slightly keeled below: corolla yellow, 10-12 
mm. broad: stamens 10-20: capsules ovoid, or oval-ovoid, shorter than the sepals or
