We examine patterns of variation in 12 continuous morphological traits, chloroplast DNA sequences from 10 intergenic spacer regions (petA-psbJ, psbk-trnS, psbM-trnD, rpob-trnC, trnC-trnD, trnGCU-trnG2S, trnFM-trnUGA, atpF-atpH, trnT-trnD, trnQ-psbk), atpF, and rpl16, and Amplified Fragment Length Polymorphism (AFLP) genetic markers in Sclerocactus glaucus sensu lato (= S. brevispinus, S. glaucus, and S. wetlandicus), a complex that historically has been considered conspecific and afforded protection …

Eragrostis obtusiflora (Poaceae, Chloridoideae), a species distributed from the southwestern United States to central Mexico, has long been recognized for exhibiting morphological and anatomical features atypical of Eragrostis. Phylogenetic analyses of nuclear internal transcribed spacer sequences and plastid sequences demonstrate that E. obtusiflora should be excluded from Eragrostis (Eragrostideae) and instead be placed in Cynodonteae, although its position within this tribe was unresolved. Additional data, including anatomical and micromorphological characters, suggest a close relationship with Distichlis. However, differences in spikelet and rhizome characters prevent its inclusion in Distichlis. Therefore, the species is transferred to a newly described …

Aliso: A Journal of Systematic and Floristic Botany
Linanthus bernardinus is described as new from San Bernardino County, California. It is morphologically similar to L. killipii and L. orcuttii subsp. pacificus but differs from plants of these taxa in height, corolla length, seed morphology, and habitat. Linanthus bernardinus can be found growing in vernally moist areas within Joshua tree woodland, often in shallow depressions, or on gentle slopes, in decomposed granite sand that is surrounded by large granite boulder fields.
Sequoiadendron Giganteum (Cupressaceae) At Lake Fulmor, Riverside County, California, Rudolf Schmid, Mena Schmid
Sequoiadendron Giganteum (Cupressaceae) At Lake Fulmor, Riverside County, California, Rudolf Schmid, Mena Schmid
Aliso: A Journal of Systematic and Floristic Botany
A GPS census made on 19 June 2012 of the Lake Fulmor area, northwestern San Jacinto Mountains, Riverside County, California, revealed seven trees of the Sierra Nevada endemic Sequoiadendron giganteum (Cupressaceae). The trees occur in a 234-meter-long narrow strip along the northwestern side of the lake. The population appears to be naturalizing. The largest tree (45 cm DBH, about 20 m tall), planted in 1980, is reproductively mature. Its six offspring to the northeast and southwest are 3–5 m tall and do not presently bear cones.
