S. Patagonia: on lava rocks in Cordilleras (J. B. Hatcher, Feb. 1897). 



"A most distinct species showing typical adaptation to high moun- 

 tain conditions." 



4. Draba Hatcheriana Gilg n. sp. (Plate XVIII B) apud Macl., 1. c. 

 p. 444. 



Perennans humilis pulvinaris radice crassa multicipite, ramis brevi- 

 bus vel brevissimis ascendentibus reliquiis foliorum emarcidis densissime 

 obtectis; foliis apicem ramorum versus densiuscule vel dense rosulatis, 

 oblanceolatis, apice acutis, basin versus sensim longe cuneato-angustatis, 

 coriaceo-carnosis, margine hinc inde obsolete ciliatis; floribus verisimiliter 

 albidis in racemos densos vel densiusculos 10— 30-flores subcapitatos 

 collectis, scapo brevi nudo, sed bracteis euphylloideis majusculis ad pedi- 

 cellorum basin evolutis; sepalis rubescentibus, late obovatis, apice rotun- 

 datis; petalis quam sepala plus sesquilongioribus, in parte 2 / 5 inf. anguste 

 unguiculatis, superne valde dilatatis orbiculari-obovatis rotundatis; sta- 

 minibus normalibus; ovario late obovato, crassiusculo, conspicue compresso; 

 stylo brevi, crasso, stigmate capitato. 



5. Patagonia: by Rio Coy Inlet (Hatcher, Nov. 1896). 



The plant rises like a cushion, about 2 — 2,5 cm above the ground. 

 Its rosette-leaves are 12 — 13 cm long, at their upper part about 1,5 — 2 mm 

 broad. The inflorescence is on the whole about 1,5 cm high, of which 

 the flowerless part comprises 1 — 1,5 cm. The bracts are 3 — 5 mm long, 

 1 mm broad. The pedicels are about 3 mm long. The calyx leaves are 

 2,5 mm long, nearly of the same breadth. The petals are about 4 mm 

 long, in the upper part 2,5 mm broad. 



"This new species appears to me to be closely allied to Draba Spe- 

 gazziniana Dusen (Gefasspflanzen der Magellanslander, p. 177) = Draba 

 oligosperma Spegazzini. Probably it does net belong to the genus Draba; 

 but so long as we are unable sharply to define the generic limits of the 

 South American species of Cruciferae, insert it provisionally in Draba. 

 It does not belong to Braya." (Ernst Gilg.) 



5. Acaena Alboffii (Alboff sine nomine) Macl.. 1. c. p. 477. 



Low, from thick rhizome, with old leaves about the base, branching 

 into floriferous stems and sterile scions. Stems low. blackish, few-leaved, 

 apically naked, subglabrous. Radical leaves short-petiolate, ovate-oblong, 

 pubescent beneath, once-pinnate, with about 2 leaflets; these small, obo- 

 vate-cuneate, apically cuneate-incised. Head solitary, large. Stamens 6. 

 Styles long plumose, blackish. Fruit small, spines 4, short-glochidiate. 



Fuegia: alpine meadows above Ushuaia (N. Alboff).
