the appearance of Scilla indica, Boerhaavia diffusa, and Evolvulus 

 alsinoides in flower. On July 7th, vegetation was in profuse growth. 

 In addition Kyllinga triceps was in flower in the uncultivated part, and 

 an enormous number of Lochnera pusilla in the cultivated strip. On 

 July 21, Gyanotis tuber osa and Gommelina Forskalcei were a marked 

 feature of the area, and among the grasses'. Tripogon Boxburghianus 

 was in flower, marking with its brown colour the poorer spots. The 

 larger and coarser grasses seemed to be about to flower, and Andropogon 

 monlicola had shown some inflorescences. Striga densiflora was visible 

 on August 8, in flower. Gyanotis fascieulata flowered on August 19 

 particularly on the poor and rocky spots, and on the same date 

 Andropogon contort us, the main spear-grass, began to flower all over 

 the area. On August 21, Striga lutea and Lagasea mollis flowered, 

 and later in the month Leucas longi/olius, Pulicaria Wightiana, and 

 Andropogon pertusus. In September Tripogon Boxburghianus was 

 drying up, but Hcliotr opium merifolium and Zornia diphylla were in 

 flow6r, along with Alysicarpus species, and Indigo/era species. The 

 Evolvulus alsinoides was not less prominent. Later appeared 

 Lepidagathis cristata, Apluda varia, Heylandia latebrosa, Panicum 

 Havidum. and Andropogon triticeus. Tripogon Boxburghianus was, on 

 October 21, putting out new growth on account of the late rains. On 

 this date also Thelepogon elegans was in flower, and Anthistiria 

 ciliata and Andropogon pumilas were also flowering. 



The above very rough list will give some idea of the facies of the 

 vegetation at various times of the season. It will be noted that there 

 are three kinds of plants. (1) shortlived vernal plants like Scilla ; (%) 

 late season plants like Heylandia ; and (3) plants of the whole season 

 like Evolvulus. 



The Quadrats. 



Quadrat 1 is on poor soil. Before the rains broke it had on it mats 

 of an unknown grass in a dry condition. These never sprouted, but 

 appear to be of Andropogon contortus. On the break of the rains a 

 sparse vegetation broke out all over the quadrat. One plant of Evol- 

 vulus alsinoides took possession of a central position, and gradually 

 spread its arms over the greater part of the square. The early grass 

 of the quadrat was Tripogon Boxburghianus, and the late one Andro- 

 pogogon contortus. A few plants of Oropetium Thommim, a minute 

 and exceedingly xerophytic grass, were also found. This quadrat was 

 twice nearly dried out. 



Quadrat 2 is situated on a spot much lower down with more 

 water and soil- The difference in vegetation is striking. The early 

 grasses were Cynodon dactylon and Setaria glauca. Later appeared,
