Obs. Secundum descriptionem, a Cl. Philippi (Phil., An. Un. 
chil. XC, f. 614) ad V. tridactylitcs Lag. ducenda; specimina 
mea cum diagnosi citata Philippiana omnino conveniunt sed sat a 
diagnosi Lagascana recedunt !

Y{.ab. In pratis siccis sabulosis prope Lago Argentino, anno 1884

Ohs. Rami longiusculi gráciles (16-40 cnt long. = 1-2 mm crass.) 
deorsum nudi prostrato-diífusi sursum arquato-adscendentes, 
parce foliosi, internodiis longiusculis (2-5 cnt long.), parum 
ramulosi, omnes glaberrimi, e terete obscure tetragoni laeves v. ad 
bifariam tenuiter bistriati; folia internodiis breviora opposita, ad 
axillas folióla 2-4 vix minora gerentia, crassiuscule membranácea 
glaberrima, viridia v. subglaucescentia uninervia spathulata v. 
obovata, ápice saepius obtuse rotundata, deorsum longe cuneato- 
attenuata (10-25 "^"^ ^ong. = 2-8 mm lat ), infera majora et latiora 
supera breviora et angustiora (saepe linearla v. lineari-lanceolata) 
non petiolata, basi linea angustissima membranácea connexa, quan- 
doque integerrima quandoque utroque latere, v. uno latere tantum, 
lobo V. dente plus minusve evoluto donata, lobis semper obtusis; 
spicae in ramis pedunculiformi-elongatis (30-80 mm long.) nudis v. 
sub ápice (5-15 mm sub capit.) foliolis 2 linearibus (rarius capitula 
I V. 2 abortiva foventibus) ornatis, apicales, 8-i6-florae, primo 
capitato-compactiusculae (15 mm alt. et 15 mmlat. ), post anthesin 
relaxato-spicatae (30 mm long. = 5 mm diam ); bracteae lineares v. 
lanceolatae (2,5-3 mm long. = i mm lat.) acutiusculae adpressae 
hirsutulo-pubescentes; calyx tubulosus subteres (8 mm long. = 2 
mm diam.) obscure 5 costatus ápice brevissime 5-dentatus, dentibus 
triangularibus subacutis subaequalibus, extus adpresse canescenti- 
pubescens intus glaber; corollae aurantiacae tubus elongatulus (12-16 
mm long. = i^ió nim diam.) subteres, ápice vix inflatulus atque 
lenissime incurvulus, extus glaber, intus retrorsum hispidulus, limbo 
patente, lobis obovato-truncatis leniter emarginatis coronatus; sta- 
mina 4, tetradynama, antheras flavas exappendiculatas includens. 
Fructus desunt. 
Species Verhe7iae {Glandularme) Jiavae Gilí. & Hook. habitu si- 
millima, sed foliis crassioribus minus incisis et praecipue anthera- 
rum appendicibus deficientia mox dignoscenda.
