The lush young Crassula subaphylla var. subaphylla leaves are obliquely barrel-shaped with conical tips. Their orange-yellow tips curve in, contrasting against the pale green surfaces of the leaves. Slightly fused at the base, these young leaves angle up, more than old ones do.
The red colouring on young stem parts changes abruptly at a particular node, showing where new growth began on the older, grey-brown stems after the last rain.
The deviant-looking stems in picture with long internodes between the smaller than usual leaves are peduncles of the stem-tip inflorescences out of sight higher up.
At the plant base the stems have lost their leaves. This is where some woodiness may develop in the stems, starting from the base (Smith, et al, 2017; iNaturalist).
