1. Phyllotaxy alternate, rarely pseudowhorled at apex of branches........................................................................... 5
2. Monocarpic plants; stem erect, not branched, with five or more leaves per node; inferior lobe of corolla free from the apex to near base............................................................................................................... S. sulfureus
2. Polycarpic plants; stem decumbent to sub-erect, branched, with (2–)3(–4) leaves per node; inferior lobe of corolla free only at the apex....... 3
3. Plants entirely glabrous........................................................................................... S. psilophyllus
3. Plants tomentose, especially in the veins of abaxial surface of leaves and peduncles................................................ 4
4. Stem sub-erect, poorly branched, leaves lanceolate; corolla bicolor, tube red, with lobes yellow to greenish.............. S. westinianus
4. Stem decumbent, very branched, leaves ovate to widely ovate; corolla unicolor, entirely yellow......................... S. flavescens
5. Hypanthium hemispheric......................................................................................................... 6
5. Hypanthium obconic............................................................................................................. 9
6. Corolla tube near the same size of the lobes, greenish; corolla lobes falcate; anthers strongly curvate, with a dense golden-yellowish tomentum........................................................................................................ S. umbellatus
6. Corolla tube at least five times longer than the lobes, red to orange; corolla lobes triangular; anthers slightly curvate, glabrescent or with a sparse white tomentum..................................................................................................... 7
