The information has been gathered from numerous sources-botanical journals, government publications, etc.-that are not generally available to the teacher and student. An annotated list of :publications on the botany of Texas has been prepared for the aid of teachers of botany, and is appended hereto.Item Cathodic Protection of Metals in Ice Plants(University of Texas at Austin, 1943-01-15) University of Texas at AustinItem Exchange of Carbon, Nitrogen and Phosphorus in Lavaca Bay, Texas Marshes: Volume II.

C.; Whelan, M. E.; Min, D. H.; Min, D. H.Coastal salt marshes are natural sources of methyl chloride (CH3Cl) and methyl bromide (CH3Br) to the atmosphere, but measured emission rates vary widely by geography. Here we report large methyl halide fluxes from subtropical salt marshes of south Texas. Sites with the halophytic plant, Batis maritima, emitted methyl halides at rates that are orders of magnitude greater than sites containing other vascular plants or macroalgae. B. maritima emissions were generally highest at midday; however, diurnal variability was more pronounced for CH3Br than CH3Cl, and surprisingly high nighttime CH3Cl fluxes were observed in July. Seasonal and intra-site variability were large, even taking into account biomass differences. Overall, these subtropical salt marsh sites show much higher emission rates than temperate salt marshes at similar times of the year, supporting the contention that low-latitude salt marshes are significant sources of CH3Cl and CH3Br.Item Letter to H.B.

Sparse plant remains were recovered. Analysis of the origin of this heterogeneous fossil biota indicates that a brackish marsh was periodically inundated by freshwater runoff. The presence of a marsh clam not known living in the area today is significant; the fossil site is reconstructed to have been a brackish marsh habitat at elevation of 3.6 meters above mean sea level. A brackish marsh at this elevation may indicate high sea levels, although existence of nontidal brackish marshes are known from the lower Texas coast. Changes in river flow and seasonal distribution of local precipitation, and/or regional runoff, are postulated to explain the existence of a saline marsh in an area where this biotype is extremely rare today.Item Research and the Range(University of Texas at Austin, 1952-11-01) Whaley, W.
