Hibiscus schizopetalus (Masters) Hook. But. Mag. t.6524. 1880. Hibiscus rosa- 

 aineusis schizopetalus Masters, Gard, Chroii. 12 : 272. 1879. 

 I was surprised to find this very showy Hibiscus growing in tv garden at La Paz, 

 June 14, 1897 (No. 1325). The very peculiar lacerated petals are unlike anything in 

 this "eiius I have ever seen. A good account of the species, with colored illustration, 

 appears in the Botanical Magazine for 1880.

Collected by Mr. E. W. Nelson, near Chicharras, State of Chiapas, altitude 6,000 

 feet, February 12 to 15, 1896 (No. 3807), and since cultivated in the greenhouse of the 

 Department of Agriculture, where it flowered in January, 1898 (J. N. Rose, No. 4027). 

 It is a very pretty (lowering shrub and worthy of a place among plants of this class. 



Malvaviscus palmeii Baker f. Contr. Nat. Herb. 3 : 313. 1895. 



Collected by Mr. E. W. Nelson on roadside between Mascota and San Sebastian, 

 Jalisco, March 14, 1897 (No. 4061). 



This species has only once before been collected. 



Malvaviscus piinglei Baker f. Am. Jonru. Sci. 50: 175. 1895. 



A shrub fully 6 meters high; with leaves 15 to 18 cm. long; flowers very large and 

 showy; petals 7.5 cm. long, white; stamen, tubes nearly 15 cm. long, extending fully 

 7.5 cm. beyond the petals. 



Collected along a garden fence in a little village between Monte Escobedo, Zaca- 

 tecas, and Colotlan, Jalisco, August 28, 1897 (No. 2670). 



This very showy plant has only once before been collected, and then from the 

 state of Michoacan. I saw only a single plant, and supposed at the time it had 

 been planted, as it was growing on the edge of a garden. 



I have partly characterized the plants as above in order to bring out certain 

 unpublished characters, as well as to show that the size of the flowers and leaves 

 is even greater than was at first supposed. This is by far the most showy plant of 

 the genus which I have yet seen from Mexico. 



SIDA.
