THE PHANEROGAMS OF THE JUAN FERNANDEZ ISLANDS I OQ 



it was observed by us: Pto Frances, c. 360 m, several trees, c. 500 hi, rather 

 common; C. Chifladores, on the ridge; ridge between Q. de la Piedra Agujereada 

 and Q. Laura, 600 — 650 m, numerous trees; C. Centinela, not uncommon; in 

 the depression between Damajuana and Yunque, c. 600 m, some trees; Q. Dama- 

 juana, c. 250 m, rare; slopes of El Yunque; V. Colonial, Q. Gutierrez, c. 300m, 

 one tree (no. 50); Q. del Monte Maderugo, rare; Q. Seca, 435 m, one tree; 

 northwest slope of Co Piramide, 600 m, a few trees; on the inaccessible crests 

 round Portezuelo, 600-650 m, many groups; C. Salsipuedes, solitary specimens 

 600 — 650 m; Pto Ingles, west quebrada, several groups from 190 m and upwards 

 (fl.-fr. 20 /i I7> no. 310 J\ 314 $); south side of the island, high cliffs east of 

 Yunque, scattered in the altitude of 7 — 800 m (fr. March 1917); B. Villagra, 

 Q. de la Choza, 3 — 400 m, numerous trees. 



Drude placed Jucuiia in the subtribe Iriarteae, but the male flowers, first 

 found by JOHOW, are symmetrical and the stigma almost apical. It comes 

 nearer to Morenieae, but it differs from both in being strictly dioecious. It 

 seems better to make it the type of a separate subtribe. 



Area of distribution: Endemic in Masatierra; monotypic. 



Bromeliaceae. 

 Greigia Regel.

Truncus lignosus inferne longe repens nee non radicans, dein curvato-

 18 mm lata, dein sensim angustata, acutissima, longissime aculeata et apice

Masatierra: Bertero! — Gorge above Pangal, c. 660 m, on humid soil 

 in dark Dicksonia-fovest; one specimen growing on a fallen trunk. According 

 to some of the islanders, the same plant has been observed on the high crest 

 south of Pto Ingles. 



After a diligent search in many places, we rediscovered this extremely 

 rare plant in a very remote corner. Unfortunately, none of the few specimens 

 observed were fertile, nor did they show any sign of ever having produced 

 flowers. Possibly the inflorescence is terminal, and the plant attains a great 

 age before it flowers. The stem is simple, or perhaps branched at an early 

 date, the branches becoming separated. The shoot is perhaps monocarpic. 



On Bertero's specimen in Kew is written: » Folia maxime similia Gregia 

 Pearcei Mez, vide Bromel. 47 », very likely written by Mez, who quotes the 

 Kew specimen. The vagina is broader in G. Berteroi, and it differs from other
