landi; it is, at any rate, not C. guatemalense. The second is of a plant collected by 
Wercklé and listed! by Christ as Cibotiwm guatemalense. Several specimens of this 
in the U. 8. National Herbarium, received from Doctor Christ and so labeled in his 
hand, are Dicksonia navarrensis Christ. So far as can be ascertained, C. guatemalense 
is strictly confined to Guatemala. 
The following specimens have been examined: 
GUATEMALA: Santa Cruz, Alta Verapaz, altitude 1,380 meters, John Donnell Smith 
1505 (5 sheets), Rio Frio, near Santa Cruz, Alta Verapaz, von Ttirckheim 
II. 2113 (4 sheets). Without locality, Salvin & Godman (ex herb. Kew).

Dicksonia wendlandi Baker, in "Hook. & Baker, Syn. Fil. ed. 2. 460. 1874. 
Type LocaLity: Guatemala, Wendland. 
DistriBUTION: Probably confined to Guatemala. 
InLustRATION: Hook. Sp. Fil. 1: pl. 30A (as C. schiedet).? 
Cibotium wendlandi differs widely from the other American species of this genus 
in the persistent, appressed-hairy covering of the costae and costules, and in its 
greenish under surfaces. A close examination, nevertheless, shows the underside 
of the leaf tissue to be very minutely papillate, though not pruinose. 
Christ has reported® this species from Chiapas, Mexico, upon specimens collected 
by Munch, and has subsequently 4 given the further data: “El Zontehuitz, altitude 
2.858 meters (Munch 104).’’ At the latter reference he lists also a “‘very similar” 
Costa Rican plant (Tonduz 10697) which, though referred to C. wendlandi, is said to 
“approach” C. guatemalense. This number (10697) is again mentioned’ by him 
the following year, under C. wendlandi, as distinct from C. guatemalense; and again 
in 1907° (here incorrectly as no. 10797) as C. wendlandi, ‘‘distinguished from C. guate- 
malense by its hairy surface and greater dimensions.’’ The plant in question (no. 
10697) is represented by two excellent specimens in the U. 8. National Herbarium, 
one of these received from Doctor Christ. It is not a Cibotium, but an apparently 
undescribed species of Dicksonia. Under the circumstances the Mexican record 
(Munch 104) must be considered as exceedingly doubtful, not only for the species 
C. wendlandi but for the genus Cibotium as well; the plant is probably a Dicksonia. 
Cibotium wendlandi is apparently a species of the semiarid regions of the Pacific 
coast, which probably accounts for the denser vestiture of the leaf surfaces. The 
following specimens have been examined: 
GUATEMALA: Without locality, Skinner 22 (ex herb. Kew); Wendland (ex herb. 
Berol.). Guatemala, Depart. Guatemala, altitude 1,350 meters, John Donnell 
Smith 2423 (4 sheets).” 
EXPLANATION OF PLATE 32.—a-e, Cibotium wendlandi; a, fragment (from Kew) of Skinner’s Guatemalan 
Specimen; b, fragment (from Berlin) of Wendland’s Guatemalan specimen (type collection); c-e, Guate- 
mala, John Donnell Smith 2423, c being a small subapical pinnule, d and e the fifth pair from the base 
(inferior and superior, respectively); f, g, Cibotium guatemalense; {, Guatemala, John Donnell Smith 1506, 
a middle inferior pinnule; g, Guatemala, von Tiirckheim II. 2113, one of the larger superior pinnules.

2 This illustration has such slight resemblance to C. schiedei that the writer wrote 
to Kew, asking the source of the material figured. The reply (May 2, 1910) states 
that the figure was probably drawn from Skinner’s no. 22. A pinnule of this, for- 
warded at the same time, is C. wendlandi.

ravine bounding a little hacienda called Aceituno, not far outside Guatemala City.
