erect, sparingly branched proximally, slender, 15–35 cm, sparsely glandular-pilose; small axillary tufts of leaves absent.

erect or trailing, branched, pubescence confined to alternating lines of short, crispate to more elongate hairs; flowering stems erect, 1–6(–8) cm in pulvinate plants, to 20 cm in creeping plants, pubescence spreading to retrorse; nonflowering shoots creeping, elongate, 1–30 cm, with terminal, fleshy, gemmaelike buds; small axillary tufts of leaves absent.
