In marshy situations Phrynium and Alpinia grow in dense 
masses supplying a never failing stoch of fodder for wild and 
domesticated elephants. In shallow lakes we tind a distinctive 
type of vegetation such as Enkvdra fluctuins, Granc^ea^ Hy perin- 
eum japonicum^ Ejuisetum dehile^ Polygons, the rare little Pilea 
peploides^ Mimulus^ Toreni^^ Sajittaria. Ottelia alismoides^ Pota^ 
mogeton, the bristly Aroid Lasia helerophylla, Coix lachryma^ 
ArundOf Saccharum cylindricum, S. sponlanetcmy Anthistiria 
gigantea^ Cyperus of many species, Equisetum debile^ etc., and 
floating on the surface, Lemna anJ other stagnant water plants. 
The ordinary herbaceous vegetation is too varied to allow of 
even a moderately exhaustive list to be given here. • The majority 
consist of weeds of cultivation common to all the warmer parts 
of India. The following selection may serve to illustrate the 
subject. Ranunculus sceleratus is common in marshes. Nastur* 
tium indicum; AEnanthe bengalensis ; Seseli dauci folium ; Stellaria 
media^ covering the banks of ponds ; Fragaria indica ; Hydrocotyle 
rotund ifolia ; Ammannia rotundifolia ; Blumea of several species j 
Xanthium strumarium, in great quantity in waste places; Vernonia 
cinerea ; Saussurea affinis ; Crepis japonica ; Gnaphalium luteo- 
album; Gnaphalium indicum; Siegesbeckia orientalis ; Spilanthes 
Acmella ; Lobelia affinis ; Verbena officinalis^ Mazus^ Vandellia ; 
Torenia^ Olclenlandia^ several species of Hedyotis and Ophiorrhiza. 
Cynudon dactylon forms good turf on cleared plots. On river 
banks are coarse grasses, sedges, Rumex rnaritirnuSy Elatostema 
rupestrCi and several species of Polygonum, Labiates are com- 
mon, such as, Stachys oblongifolia^ Leucas Itnifolia^ Elsholtzia 
blanda^ Mosla dianthera, Leonurus sibirica^ Perilla ocimoides^ 
etc. 
Having obtained a fairly complete collection of plants in flower 
and fruit in the forest of Makum I returned to Dibrugarh where I 
remained two days to make ’‘arrangements for an excursion to 
Sadiya, about 60 miles further up the Brahmaputra. The town 
of Dibrugarh is well laid out and drained and the roads are bordered 
by avenues of shady trees. Tectona grandis^ Jamarindus indtea
