these and to America. Serpicula* is common to India and Africa, being found in the 
Mauritius, the Cape of Good Hope, and the Indian Peninsula ; Haloragis in the last, 
as well-as in New Holland. ° 
70. CERATOPHYLLEZ. 
This, like the former order, being aquatic, is distributed over a wide extent, and 
species of the genus from which the order is named, are found both in Europe and India. 
C. muricatum, an Egyptian plant, is also found in India; as well as C. tuberculatum, 
Cham., considered with doubt to be the C. verticillatum, Roxb., which is found in the 
pools about Calcutta. . 
71. LYTHRARIZ. 
The Lythraria, called also Salicarig, are divided into tribes, which differ in their 
geographical distribution ; the Lagerstremie being tropical, as Lagerstremia occurs in 
India, China, and the Islands: Fatioa appears to be only a variety of L. parviflora. 
The true Salicariee, like other tribes containing aquatic plants, or those delighting in 
moist situations, are distributed over a wide extent, and very different climates ; thus, 
Rotala, Pemphis, and Ameletia, are exclusively Indian, extending from the islands of the 
Indian Ocean up to the Peninsula and Bengal, and the last as far as Nepal. Lawsonia 
exists in a cultivated state in most parts of the Oriental Region. Grisiea is found in 
India, China, and 8S. America, and Ammania in the warm parts of both hemispheres. 
Lythrum, found in Europe, America, and New Holland, exists also in the Himalayas, 
the species figured t. 46, being indigenous in Cashmere. This is closely allied to Z. vir- . 
gatum and Salicaria; the latter remarkable for being found in New Holland, as well as 
in Europe.

* The authors of the Prod. Fl. Indie Penins., in their observations on this genus, have remarked “ that this 
genus must not be confounded with the other Serpicula in Wallich’s list, n. 5048,” although they have been 
considered the same by me, and referred to the same natural order. Considering that the plant alluded

Immediately on my arrival from India, and when 
Dr. Wallich was on the eve of departure, and much pressed for time, I offered to Index his Catalogue,
