856 C. SKOTTSBERG 



brown with prominent white leaf scars, old bark blackish, 5 — 7 mm thick, deeply 

 and coarsely furrowed. Leaves coriaceous. Collected in August 1908 and 191 7 

 with flowers, fruit and growing innovations (Skottsb. j. 58, fig. 1 1) which, to judge 

 from observations made in 1916, flower in the beginning of December and bear 

 a new set of innovations in the uppermost axils; in the middle of the month 

 stronger ones had a leafy stem 9 cm long with internodes of i — 1.5 cm, while the 

 fruiting mother shoot was losing its last leaves. Innovations of this size will flower 

 later during the summer, so that 2 generations of branches are formed each season 

 and a third during the winter. Fig. 19 e illustrates a branch examined April 24, 

 1917: I, now in fruit, is supposed to have flowered in January; of the three branches 

 marked II, one is quite small, but two are in full bloom and bear growing buds (III). 



Seeds sown 22.3. 1918 gave 7 seedling in the beginning of May, of which the 

 first flowered in October, 1920, and produced fruit; see Fig. 20 a, where 2 strong 

 innovations are seen at the base of the peduncle. Grows well in a temperate house 

 and is easily propagated by cuttings. 



Eryngiuin inaccessum Skottsb. Only known from the precipitous cliffs of 

 Portezuelo de Villagra, Masatierra, almost 600 m above sea-level. A miniature 

 tree with the same morphology as the former, but very slow-growang and hardly^ 

 mUch taller than i '2 m, with a main stem 20 cm long and 2 — 2.5 cm thick. Bark 

 dull brown, ringed like an earthworm (PI. 12:2, this vol. no. 7). Leaves stiff cori- 

 aceous, with pungent teeth; for particulars, see 1. c. 158. The material secured 

 (25.12. 1916) was past flow'ering, wath immature fruit. Two innovations seem to 

 be the rule, but in cases only one is developed; they were short and sessile at 

 the end of December. Bud protection as in the former. The leaves are not shed 

 as early as in this but stay on long after they have become brown and dry. 



Eryngium sarcophylliim Hook, et Arn. Confined to the coast cliffs of Masa- 

 fuera, rare. Johow calls it a shrub or subshrub, but its architecture is exactly the 

 same as in the former two; see Skottsb. j. pi. 5:5, where an entire specimen, collected 

 28.8. 1908, is figured. A miniature tree not over 40 or 50 cm tall; main stem 

 10 — 20 cm, about i cm thick, more or less clothed with old leaves. Leaves linear, 

 very succulent, resembling the leaves of a Kleinia or McsembryantJiemiim . The 

 plant figured 1. c. is regularly dichotomous, with the old, dry head of the main 

 stem still preserved, and the two vegetative-floral branches each with two inno- 

 vations. To judge from our observations in February 1917, these innovations 

 probably flowered in Jan. — Feb. 1909, and as the flowering specimens seen in 

 Feb. — March 1917 had well developed innovations, three generations of fruiting 

 branches may be formed during one year. 



Seeds sown 21.9. 19 18 rested until March 19 19, when a few germinated; others, 

 sown 27.3. 1919, produced seedlings in May the same year. Most of them died soon, 

 but one flowered in February 1920. This plant is seen in Fig. 20 b. There is one 

 axillary shoot at the base of the peduncle, another in the axil of the lowest leaf still 

 left, a third at the point where the series of longer internodes begins, and several 

 sprouting from the base of the stem and forming a dense tussock. Nothing like this 

 was observed in nature. Unfortunately the specimen soon died and the seeds did 

 not germinate.
