Determination
Note:
This is a problematic collection. In its overall habit and colouration it compares exceedingly well to the two Tasmanian collections of D. eucamptodontoides that I have seen (both in WELT). However, in NZ D. obesifolium is variable with respect to costal length (failing far below the leaf apex to sometimes percurrent and variable in single shoots), set of leaves, shoot form (cuspidate or not), and pigmentation (only rarely black, as in this collection). I continue to believe that Glenny 5133 (as well as the similar JK Bartlett collection from Percy Saddle) is merely aberrant material of the widespread D. obesifolium.
I have seen too little material of D. eucamptodontoides (and no type material) from Tasmania to allow the firm conclusions about the status of that name. If D. obesifolium were to be conspecific, the Tasmanian name would have priority.
CHR 532469 (AJF 10057) from Kelly Range is exceedingly like the present collecton in overall habit, costal length, colouration (albeit it is not so black as Glenny 5133), leaf shape and dimensions. CHR 532469 in my opinion is also aberrant D. obesifolium.
CHR 428940 (J. Child 4383) from Gertude Saddle has most costae in most leaves percurrent, while in others the costae seem absent. In other respects it is quite representative of D. obesifolium.

Notes:
Ex Herbarium, Museum of New Zealand, Wellington. WELT M . Substrate: peat. ( A single specimen from the Eyre Mts. in Southland (D. Glenny 5133) has been examined with leaves nearly black on a 20 mm portion of the stem, but representative of the species in all other respects. The pigmentation, occuring in the laminal cells walls, is interpreted as resulting from periodic inundation or waterlogging. Similar darkly pigmented plants occur in D. robustum when growing in waterlogged habitats. Allan Fife June 2000.) [See other notes enclosed.]
