Description: Crassula barklyi is a tiny annular columnar species better known by the common name Rattlesnake Buttons or Bandaged Finger the latter being aptly descriptive of the stem covered neatly and smoothly by the overlapping leaves which have membranous margins.
Note: This interesting Crassula is very common and well known in cultivation, but is better known under the name of Crassula teres. As reported in old texts the edges of the leaves of C. teres should have a transparent margin, while those of Crassula barklyi, are not without this. However the two plants are very similar (if not exactly the same) and it is hard to tell apart one from the other by body characteristic. In accordance with the variability of the species C. teres is invalid and nowadays considered as a synonym.

Habit: Crassula barklyi is a perennial-dwarf succulent shrub with erect or rarely decumbent stems, narrower than that of the closely related Crassula columnaris, longer and does not die when the inflorescence withers. Unlike its solitary relative, this species branches at the base into several attractive finger-like growths. It is very slow growing but will reach 50-90 mm.
Bodies (stem and leaves together): The stem is covered neatly and smoothly by the overlapping leaves to form a short almost cylindrical column, which has something of the appearance of a tree cone. Younger branches are almost spherical and looks like grey-green rosebuds.
Leaves: Fleshy, depressed-ovate, concave, 3-4 mm long, 10-15 mm wide, patelliform, overlapping and tightly clasping, light green, grey-green or grey-brown with deep green or bronze spots and have translucent membranous margins (about1-2 mm broad) with a fringe. Crassula barklyi like the allied Crassula columnaris possesses a dense fringe of erect, rarely slightly recurved cilia on its leaves which are capable of absorbing dew or rain water.
Inflorescence: The inflorescence is a terminal cymose capitulum partly hidden by leaves below.
Flowers: Perfumed at stems ends, tiny white stemless. Calyx lobes oblong-oblanceolate, 4-5 mm long, rounded and with fine spreading cilia, fleshy and green becoming yellow and membranous below. Corolla slender ampulliform, fused basally for 2-3 mm, cream. Lobes narrowly oblong-elliptic, 9-11 mm long, with a blunt beak. Stamens with yellow anthers. Squamae oblong-cuneate, 1-1,2 x 0,3-0,4 mm, truncate to slightly rounded, scarcely fleshy, yellow.
Blooming season: It flowers in winter (in habitat from June to August).
