﻿LITERATURE OF FURCRAEA WITH SYNOPSIS OF SPECIES. 55 



far as the leaves go it is very near F. Selloa, but until the in- 

 florescence can be studied, it is better to retain it as a species. 

 The earliest mention of the plant appears to be in the Gar- 

 deners' Chronicle, 1869, p. 587, as having been shown by 

 Linden at the Russian International Horticultural Exhibi- 

 tion of that year. The writer has unfortunately not suc- 

 ceeded in tracing Jacobi's description. Lehmann no. 8676, 

 on cliffs at 1000-1800 meters round Popayan, may be this. 

 The leaves (probably from the inner part of the tuft), are not 

 variegated; — they resemble those of Lindeni or Selloahuihave 

 not the "emery paper" under-surface; the flowers are too 

 small for F. Selloa of the Kew Herbarium. 



F. PUBESCENS, Todaro "Sopra una nuova sp. di Fourcroya" 

 (1879), pp. 9-14. 



From the figure this can hardly be the "pubescens" of 

 Baker in Bot. Mag. 7250 (1892) which is the same as F. un- 

 dulata, Jacobi, assuming at least that the undulata of Bot. 

 Mag. 6160 (1875) represents Jacobi's species, which seems to 

 the writer practically certain. The degree of pubescence 

 evidently varies in these dwarf Furcraeas within somewhat 

 wide limits; it is remarkable that they share this character, 

 which is altogether absent in the "Giganteae," with the ar- 

 borescent ''Scrrulatae." 



From Todaro's description, and the representation of a 

 stem-leaf on pi. ii. (fig. 5, omitted in the explanation), F. 

 puhescens would appear to differ from all known Furcraeas 

 by the remarkable arrangement of the leaves which extend 

 to the scape, and, though modified in shape, only disappear 

 at the base of the first branch of the panicle. 



F. spiNOSA, Targioni-Tozzetti in Obs. Bot. dec. i. & ii. (1808) 

 pp. 33-36, tab. iv. fig. 1-16, 27, 28, & 32 = Rodati, Ind. 

 Hort. Bot. Bonon. (acc. Obs. de Agaves spec.) p. 27, t. 1. 

 On the whole this would seem to have been F. tuber osa, 

 and if this were demonstrable ^'F. spinosa," as the name, 

 would have priority; but the figures indicate a shorter, rather 

 narrow leaf, and may represent a plant collected at Sta.
