— Frenela Muelleri, Parlat. in DC. Prod. xvi, 2, 450. This species name has been mixed up with C. fruticosa, R.Br., and I will try and clear the matter up.

C. fruticosa, R.Br. ex L. C. Rich. Conif. 49 (1826), and therefore Frenela fruticosa, A. Cunn., ex Endl., l.c. It is probably a Tasmanian specimen of Frenela australis, R.Br., that R. Brown had originally designated under the name of Callitrisfruticosa, which does not occur in his herbarium." — (B.Fl. vi, 239)

Mueller often labelled Blue Mountain specimens of C. Muelleri "C. australis, R.Br.," in the early days.

Mueller wrote to me, 8th June, 1891, —

Callitris fruticosa awaits also yet elucidation. I think it is one with very coarse foliage (unusually thick branchlets) and usually of shrubby growth, and originally only about Port Jackson, where it way have become extinct.

Neither Bentham nor Mueller saw Brown's species. Bentham surmised that it was from Tasmania, Mueller from Port Jackson. If Mueller's view is correct, then it is the plant we know as C. Muelleri.

Parlatore, in DC. Prod. xvi (2) 450, gives Frenela fruticosa, var. arborea, Mueller, as a synonym of F. Muelleri. I agree with this, having seen the specimens.

I have seen L. C. Richard's work. T.18 consists of an elaborate series of detail drawings of C. rhomboidea (cupressiformis) under No. 1. No. 2 (on the same plate) consists only of a drawing of one cone, under the name C. oblonga. The drawing might have been better, but I see no reason to differ from those who attribute it to the Tasmanian C. oblonga, especially as in the brief description we have "squamis oblongis," which those of C. Muelleri certainly are not. Richard gives as a synonym of his species "Callitris fruticosa, R. Brown, M.S." After describing his species he adds "Habitat ad portum Jackson. Ex Londino specimena ad me misit, R. Brown." It seems to me that the confusion has entirely been caused by attributing this specimen to Port Jackson instead of Tasmania.
