    • Biogeographical Distribution of Salt Marsh Halophytes on the Coasts of the Sonoran Desert

      Yensen, N. P.; Glenn, E. P.; Fontes, M. R.; Environmental Research Laboratory, University of Arizona (University of Arizona (Tucson, AZ), 1983)
      Twenty-four species of intertidal halophytes were recorded from 15 coastal salt marshes of the Sonoran desert. The Pacific salt marshes were found to be the most diverse, with 14.4 species per marsh, while the western Gulf of California had 8.9, and the eastern Gulf, 13.7. A low species diversity was found in the northwestern Gulf due to the absence of mid- and high-zoned halophytes. High-zoned species were geographically patchier on all coasts. The species formed three elevational groups within the intertidal zone: LOW: Spartina foliosa Trin, Distichlis palmeri (Vasey), Rhizophora mangle L., Laguncularia racemosa (L.), Avicennia gerimans (L.), Salicornia bigelovii Torr., S. europaea L., and Batis maritima L.; MID: Salicornia virginica L., Suaeda californica S. Wats., laumea carnosa (Less.), Sesuvium verrucosum Raf., Limonium californicum (Boiss.1 and Cressa truxillensis H.B.K.; HIGH: Salicornia subterminalis Parish, Allenrolfea occidentalis (S. Wats.), Frankenia grandifolia Cham. and Schlect, F. palmen S. Wats., Monanthochloe littoralis Engelm., Distichlis spicata (L.), Suaeda fruticosa (L.), Atriplex barclayana (Benth.), A. canescens (Pursh) and Sporobolus virginicus (L.). Thirty additional species were recorded in the supralittoral zone.

    • Bizarre Seed Patterns in Plants of the Indian Arid Zone

      Bansal, Rajinder P.; Sen, David N.; University of Jodhpur, India (University of Arizona (Tucson, AZ), 1981)
      A comparative study of seeds of 46 plant species which abound in cultivated fields of the Indian arid zone has been made. A variety of new seed patterns discovered, some bizarre, are described. Seeds were categorized on the basis of their weights into five groups. The seeds of Polycarpaea corymbosa were found to be lightest of the species studied. Most frequently the seed weight varied among species of the same genus and among different genera of the same family. Similarly great variations in seed size were met. In general, lighter seeds were small in size and heavier ones large. The seed surfaces varied from smooth and glossy to ornamented and rough. The seeds of Farsetia hamiltonii possessed wings which increased their surface area. The color of the seeds in most cases was brownish- yellow to dark brown. Only few seeds were black. Description and illustration of the diversity will perhaps hasten an understanding of the developmental sequences and adaptive values (under arid conditions) of the bizarre seed patterns.

    • Bouteloua eludens: Elusive Indeed, But Not Rare

      Reeder, John R.; Reeder, Charlotte G.; University of Arizona (University of Arizona (Tucson, AZ), 1990)
      Although considered to be rare and represented by only a few collections, the most recent in 1960, Bouteloua eludens Griffiths is shown to be relatively common in southern Arizona and in northern Sonora, Mexico. It has been known in Arizona only from the Santa Catalina and Santa Rita Mountains in Pima County, a few areas along Ruby Road in Santa Cruz County, and one collection from the northern end of the Whetstones in Cochise County. Recent field work has demonstrated that this species is by no means rare, but it is elusive. We found it, often in abundance, in all previously known sites. New localities for Bouteloua eludens are: Empire, Rincon, and Sierrita Mountains of Pima County; Dragoon, Mule, Swisshelm, south end of Whetstone Mountains, Tombstone Hills, and Guadalupe Canyon of Cochise County; the Canelo Hills, Mustang and Patagonia Mountains of Santa Cruz County.
