specimens from the above-named places, and from Broken 

 Hill, I have never seen any with the exappendiculate perianth 

 of .4. angulata. A. Muelleri, Benth. "''Annual Saltbush." 

 North Park Lands of Adelaide: Woodville; Port Adelaide: 

 Roseworthy (Dist. A); Gladstone (Dist. N). 



Amarantaceae. 



Trichinium seminudum, sp. nova (tab. vi.). Herba 

 perennis circiter SO cm. alta, caulibus erectis vel ascen- 

 dentibus ramosis pilosinsculis, foliis glabrescentibus, radi- 

 calibus lanceolatis in petiolum alatum angastatis cum petiolo 

 7-llf. cm. longis, caulinis brevioribus latioribus vix petiolatis, 

 spicis primum hemisphaericis demum ovoideis vel oblonc/i* 

 Jf.-5 cm. longis 3 cm. latis, bracteis bracteolisque ovato- 

 lanceolatis acuminata parce pdosis 8-9 mm. longis, iUis 

 brunneis his fere albis, perianthio 12-15 mm. Ion go prope 

 basin constricto, segmentis apice alb o -scar iosis medio viridibus 

 et villosis basin versus rigidis et fere nudis, diiobus 

 (iterioribus truncato-emarginatis margine inferiore ciliolatis, 

 interioribus acutis infra longe infieco-ciliatis, tubo pubescente, 

 filamentis inferne dilatatis tribi/s anantheris, stylo brevi 

 glabro, ovario supra sparse pdoso stipitato. Minnipa. Should 

 probably be placed in Series Straminea beside T. alopecuroi- 

 deum, Lindl., which it somewhat resembles in habit, but the 

 dividing line between Straminea and Rhodostachya is not so 

 well marked as would appear from the text-books. Both T. 

 macrocephalum (placed in Straminea) and T. exaltatum 

 (placed in Rhodostachya J have, for instance, the inner 

 perianth-segments ''glabrous inside," strictly speaking, the 

 difference being that the former has only a few of the long 

 marginal hairs inflexed, while in exaltatum they form an 

 intricate woolly mass which occupies the lower part of the 

 convex inner surface of the segment. None of the hairs, 

 however, rise from the inner surface itself, but only from the 

 margins. The new species differs from all others in the 

 glabrous condition of the outside of the lower part of the 

 perianth. 



T. alopecuroideum, P. v. M., var. nova rubriflorum. 

 Variat perianthio rubro, spied paulo angustiore (20-25 mm. 

 lata), cupula staminali pilis brevissimis ciliatd. Near Oodna- 

 datta (Miss Staer, November, 1914). A very handsome 

 plant on account of its long red spikes. 



Alternanthera nana, R. Br. Oodnadatta (Dist. C: Miss 

 Staer). .4. angust, > folia, R. Br. Oodnadatta (Miss Staer). 

 Not previously recorded for South Australia, the nearest 

 locality quoted being Sturt Creek, in North-western 

 Australia.
