Notes. 469 
received a specimen of a male plant collected in the Mexican State of Jalisco by 
Mr. C. G. Pringle, n. 6871, and doubtingly named Juliania adsiringens. 
The male specimen was published as Juliania mollis , Hemsl., and the fruiting as 
J. adsiringens , Schl. 
This publication had the desired effect, for it brought me a letter at the end of 
1901 from Dr. J. N. Rose, Curator in the ‘Division of Plants’ of the United Slates 
National Museum at Washington, from which I make the following extracts : — 
‘ You will also be interested in what I have to tell you about Juliania . For 
more than six years I have been at work off and on, at this genus, but for the lack of 
material I have never published anything upon it, but each time have brought back 
specimens, and this year was especially fortunate in collecting near the type-locality 
both male and female plants. In looking up the subject since my return I find that 
you have anticipated me and have published two very beautiful plates and some 
interesting notes. . . . There are, however, more than two species in Mexico. I have 
certainly four well-marked species and possibly six. . . . With regard to the position 
of this genus, I think it must be regarded as the type of a new order. I do not think 
it has any relationship to either Burseraceae or Anarcardiaceae. My conclusions in 
the field were that it must be closely related to Juglandaceae, a relationship which you 
also suggest.’ 
In this communication Dr. Rose most generously offered to send all his specimens 
and notes to me, leaving it to my judgement in what form publication should be 
effected. I gladly accepted, and through the kindness of theiTrustees of the Bentham 
Fund, Miss M. Smith made an elaborate series of drawings under my direction. As 
there were still some structural points on which we were not quite clear, and Dr. Rose 
contemplated another visit to Mexico, it was decided to publish at once a description 
of the genus, as then understood, and brief diagnoses of the species. 
III. Geographical Distribution. i. Juliania. — So far as at present known 
Juliania is confined to Mexico, and the various species occur in isolated localities 
between about 17 0 40' and 23 0 N. lat., and 97° and 104° W. long., and at altitudes of 
about 1,500 to 5,500 feet. 
2. Orthopterygium. — The habitat of the Peruvian Orthopterygiu??i Huaucui is 2,000 
miles distant from the nearest locality of any species of Juliania. The exact position 
of the only place in which it has been found cannot be given, but it is in the Province 
of Canta, in the Department of Lima, between n° and i2°S. lat. 
IV. The Affinities of the Julianiaceae. During the six years that I have 
had this small group under observation I have had opportunities of showing the 
specimens and drawings to many of the leading botanists of the world, and all agree 
who have seen them that it deserves to rank as an independent order. That being 
so, the question of its position arises, but that is a point not so easily settled in a 
linear arrangement. Taking the morphological characters seriatim, it is evident that 
the closest relationships are with the Anacardiaceae and Cupuliferae. The absolute 
separation of the sexes and the very great diversity of the floral structure of the sexes, 
associated with pinnate leaves, offer a combination of characters probably without 
a parallel. 
Beginning with the foliage, the Julianiaceae have alternate, exstipulate, impari-
