190 Notes on Cactee. [ZOE 
The sequence of the subfamilies is not changed, but is suggest- 
edin the preliminary pages. In theearlier workit ran: Subfam. 
i. Cereoideze; ii. Opuntioidee iii. Peireskioideze. In the later 
this order is reversed, the seed coats are not mentioned, and the 
classification rests principally upon the presence or absence of 
barbed setze (glochidia). It is perilous in the present state of 
our knowledge to generalize upon the surface structure of seeds 
as is evidenced by his statement that the seeds of the Cereoidez 
are “always shining, brittle and black.’’ Certainly they are not 
always shining, and they are commonly red or yellowish-brown 
in two sections of Mamillaria (Coryphantha and Lactescentes). 
‘“‘Always”’ is a dangerous word in this family of plants. . 
Some of the new species of mamillaria described by Prof. 
Coulter,* alternatus, brunneus, capillaris, densispinis, eschauzieri, 
maculatus, Pringlei, radians-pectenoides, omitted from Monog. 
Cact., have not been included in the Nachtrage, although the 
author’s attentiont was called to the matter, 
Such omissions, which are but examples of many others, it is 
. needless to say, seriously injure the value of the work. 
CEREUS GREGGII Engelm, has been found in Sierra de la 
Trinidad, Baja California, by Mr. Carlos Grabendorfer, who 
writes that it is locally known as ‘‘Reina de la Noche.”’ 
CEREUS STELLATUS Pfeiff. Too this species, according to Prof. 
Schumaun, belongs C. Sonorensis Runge Cat. & C. Simonii 
Hildm, C. Sonorensis was later described by Schumann, M. f. 
K. xi, 135, (1901). But C. Sonorensis is certainly a synonym of 
C. Alamosensis Coult., the type of which was collected at Alamos 
in Sonora. It has been collected also at Topolobampo, Sinaloa, 
by Captain Porter, by Dr. Purpus not far from Guaymas, and 
abundantly in Northern Sonora by Mrs. Main. 
The following notes were taken from plants flowering in our 
garden: 
Flowers 6-8 cm. long, nearly tubular, expansion less than 3 
cm., the whole flower with the ovary of the same color, some- 
what translucent coral-red, but of different shades in different
