Saurauia Conzattii Buscalioni in Malpighia 25 
(1918) 403, t. 6, fig. 9. 
Mexico: Oaxaca, District of Cuicatlin, San Juan Zautla, long. 96° 
40/, lat. 17°58’, June 16-22, 1898, V. Gonzales & C. Conzatti s.n. ; 
District of Ixtlin, Cerro Hueso, between San Pedro Yolox and San 
Juan Tepetotutla, long. 96°25’, lat. 17°48’, altitude 2500 m., June 
26, 1939, Schultes 695 (Keon. Herb. Oakes Ames; Herb. Gray). 
Hitherto, Saurauia Conzattu has been known in her- 
baria by two collections: the type, represented by FZ. & 
C. Conzatti s.n. (discussed below); and the collection 
by Gonzalez and Conzatti (cited above), a specimen of 
which is preserved in the Gray Herbarium. Schu/tes 695 
“as collected only a few miles southeast of the locality 
of these other collections. The plant apparently repre- 
sents a very restricted endemic, because it has never been 
found anywhere except in the District of Cuicatlin and 
the northern part of the adjacent District of Ixtlan in 
northeastern Oaxaca, where it inhabits the highest parts 
of the local mountains. 
Saurauia Conzattu is a forest-dwelling shrub up to five 
or six feet in height. It has leaves which are extremely 
large in relation to its height. Conspicuous because of its 
profusion of white flowers which measure 2.5 cm, across, 
it is at once distinguishable in the dark, wet forests of the 
limestone mountains. The slender branches and dark 
green leaves are very densely clothed with reddish brown 
setae. Saurauia Conzatti is not abundant where it occurs. 
Schultes 695 was collected from a single isolated colony 
consisting of six shrubs. No other colonies were seen.
