1893. ] Undescribed Plants from Guatemala. 3 
Hauya Rodriguezii.— Younger leaves, nerve-axils of the 
older, and ovaries, cano-pubescent; otherwise glabrate: leaves 
rhomboid-oval to elliptical (34-4 x 2-23"), abruptly acumi- 
nate, obtusely or acutely angled at unequal base, eight to nine 
lateral nerves ascending straight to marginal arches: flowers 
large: lobes of calyx equalling tube (2}—3"), prolonged to sub- 
ulate tips: petals two-thirds as long, oval: awns of anthers 
filiform (23'): style equalling petals, stigma globose (4'): capsule 
subsessile, large (2—2}"), smooth, valves plane.— Compared 
at Kew by Mr. Hemsley with the originals of described species, 
and not identified. A. elegans Hemsl., as represented in 
this series of plants by nos. 2,527 and 2,528 determined by 
that gentleman, is a closely related species, differing chiefly 
by velvety or sericeous indument, round-oval leaves abruptly 
short-acuminate and with a rounded or subcordate base, rela- 
tively shorter calyx-lobes and longer petals and style. —A 
tree with a stout trunk, 30% high.—Acatepeque, Dept. Zaca- 
tepequez, alt. 4,300", Mch.. 1892, J. D. S., (ex PI. cit. 2,529). 
Named for Sr. Icdo. Don Juan J. Rodriguez, former Minister 
of the Interior, a distinguished student of Lepidoptera, in 
memory of hospitable and courteous attentions during my 
sojourn on his estates of Capetillo and Acatepeque situated 
on the southeastern slopes of the Volcan de Fuego. 
Hauya Heydeana.—Arborescent (18%), glabrous: leaves _ 
conterminously lanceolate (3}-4}x1-1}4"), tipped with a 
gland, blotched with exudations: flowers small for the genus 
(21-28"), peduncles twice to thrice longer than petioles 
(12-18'): lobes of calyx shortly tipped, narrowly linear, ex- 
ceeding tube: petals as long, twice broader, lanceolate: stigma 
ellipsoid: capsule about an inch long with narrow (2') and 
plane valves. —A well marked species as respects both foliage 
and flowers, and especially distinct by the peduncle excep- 
tional for the genus.—Beleti, Dept. Alta Verapaz, alt. 5,000", 
Apr. 1892, Heyde & Lux, (ex Pl. cit. 2,935).— Dedicated 
to Sr. pbro. Don Enrique Th. Heyde, parish priest in Santa 
osa, as aslight but very sincere acknowledgment of my obli- 
gations to him for an extensive series of plants with dupli- 
cates, collected by him and his nephew, Don Ernesto Lux, in 
the departments of Quiché, Santa Rosa and Jalapa. Impor- 
tant additions to our knowledge of the Guatemalan flora may 
be expected from the further explorations, proposed by these 
gentlemen, of regions unknown to botanists, difficult of access,
