“15-20 ft.”); same locality, September 26, 1894, C. G. Pringle (no. 5608, st.; 
G.; leaves identical with those of the preceding no. in Herb. M.). 
ANDERSSON says that he has seen of S. paradoxa nothing but “pauca 
specimina tantum eaque deformata.’’ His statement “‘capsulae hirsutae 
longe pedicellatae, stylo nullo” does not apply to what I take for the typical 
paradoxa,. UNTH does not mention a style; he describes abnormal (androgy- 
nous) female aments, and according to his statement “amenta . . . . fructi- 
fera subtripollicaria, crassitie pollicis.” Iregard as paradoxa the plant with the 
very large fruiting catkins. This form has a distinct style which is very short 
(mostly hidden among the hairs of the apex of the ovary) in var. ajuscana, but 
this variety does not have “folia . . . . subtus nervo et venis primariis 
prominentibus ferrugineo-tomentosis” as KUNTH says, and the fruiting aments 
measure only up to 5:1.2 cm. 
Row ex, in describing S. Pringlei, apparently mixed typical forms of 
paradoxa with those of var. ajuscana. Furthermore, he seems to have had 
before him another form with glabrous pedicels (see Bot. GAz. 27:137, fig. I, 
a-b). I have not yet seen a specimen fully agreeing with RowLEE’s descrip- 
tion and figure, therefore I regard the true S. Pringlei as an obscure form not 
identical with Pringle’s no. 6795 of the different herbaria I have seen. S. 
Pringlei may belong to a hybrid between S. Rowleei and S. paradoxa var. 
ajuscana, which both occur on the Cima de Ajusco.
