Notes on Grasses (Poaceae) in Hawai‘I: 2

Box 299, st. louis, missouri 63166-0299, Usa; email: [email protected] ) additional new records for the grass family (Poaceae) are reported for Hawai‘i, including five state records, three island records, one corrected island report, and one cultivated species showing signs of naturalization. We also point out minor oversights in need of cor - rection in the Flora of North America Vol. 25 regarding an illustration of the spikelet for Paspalum unispicatum . Herbarium acronyms follow thiers (2010). all cited specimens are housed at the Herbarium Pacificum (BisH) apart from one cited from the missouri Botanical Garden (mo) for Paspalum mandiocanum, and another from the University of Hawai‘i at mānoa (HaW) for Leptochloa dubia . Anthoxanthum odoratum l. New island record this perennial species, which is known by the common name vernalgrass, occurs natu - rally in southern europe but has become widespread elsewhere (allred & Barkworth 2007). of potential concern in Hawai‘i is the aggressive weedy tendency the species has shown along the coast of British columbia, canada, where it is said to be rapidly invad - ing moss-covered bedrock of coastal bluffs, evidently to the exclusion of native species (allred & Barkworth 2007). the species has been recorded previously on kaua‘i, moloka‘i, maui, and Hawai‘i (imada 2008). -

Received: 4 March 2020; Accepted: 19 March 2020; Published: 23 March 2020 Abstract: The process of rapid urbanization has affected the composition and diversity of urban vegetation species. The process of urbanization from 2000 was analyzed in the area of "one major city with three vice cities and six groups", according to the urban master planning of Hangzhou from 2001 to 2020. The results show that dramatic changes have occurred for land use types during the ten years from 2000 to 2010 in Hangzhou, of which urban land has become the main type of land use and the area of arable land has presented serious loss. This study found that the Gramineae and Compositae species were the main groups of ruderals in 1665 quadrats, which reflected the characteristics of a few large families. The number of Monotypic and Oligotypic family/genera accounted for 67.3% of the total number of families and 97.5% of the total number of genera. -

Weaver, Jr., Ph.D., and Patti J. Anderson, Ph.D. For this period, 167 specimens were submitted to the Botany Section for identification, and 1,418 were received from other sections for identification/name verification for a total of 1,585. In addition, 57 specimens were added to the herbarium, and 48 specimens of invasive species were prepared for the Division of Forestry’s Forest Health Project. Some of the samples received for identification are discussed below: Helianthus simulans E. E. Wats. (an endemic North American genus of 49 species, occurring throughout the United States and adjacent Canada, as well as in Baja California). Compositae (Asteraceae). Muck sunflower. It is unfortunate that such an attractive plant has such an unattractive common name. Growing to more than 2 m tall, this sunflower makes a showy and impressive specimen in the garden. In its best forms, the lanceolate leaves are leathery and dark green, somewhat reminiscent of those of the oleander (Nerium oleander). The flower heads, with bright yellow rays and usually a reddish- purple disk, are borne in profusion in October and November and vary from 7-10 cm across. Although it grows at least twice as tall and the leaves are broader and not revolute (turned under along the margins), it is often confused with the very common Helianthus simulans Photograph courtesy of Sally Wasowski and swamp sunflower (H. -

Box FM730, Famona, Bulawayo, Zimbabwe Vegetation Survey of Mt Gorongosa, page 2 SUMMARY Mount Gorongosa is a large inselberg almost 700 sq. km in extent in central Mozambique. With a vertical relief of between 900 and 1400 m above the surrounding plain, the highest point is at 1863 m. The mountain consists of a Lower Zone (mainly below 1100 m altitude) containing settlements and over which the natural vegetation cover has been strongly modified by people, and an Upper Zone in which much of the natural vegetation is still well preserved. Both zones are very important to the hydrology of surrounding areas. Immediately adjacent to the mountain lies Gorongosa National Park, one of Mozambique's main conservation areas. A key issue in recent years has been whether and how to incorporate the upper parts of Mount Gorongosa above 700 m altitude into the existing National Park, which is primarily lowland. [These areas were eventually incorporated into the National Park in 2010.] In recent years the unique biodiversity and scenic beauty of Mount Gorongosa have come under severe threat from the destruction of natural vegetation. This is particularly acute as regards moist evergreen forest, the loss of which has accelerated to alarming proportions. -

History : Project Deepak
HISTORY : PROJECT DEEPAK 1. Raising & Early History. Project Deepak was raised in May 1961 with Col S N Punjh as Chief Engineer, primarily for the construction of Hindustan-Tibet (H-T) Road. The H-T Road is one of the most difficult roads ever to have been constructed in India. The 76 Km long Pooh-Kaurik sector of H-T Road passes through considerable lengths of sheer vertical hard rock stretches and huge bouldery strata embedded in sand and non-cohesive material, which is inherently unstable. The sector runs along the River Satluj crossing it at several locations. The road runs at altitudes between 1600 to 3600 meters. On the whole, the terrain and climatic conditions are very uncongenial. Many valuable lives were lost during the construction of this road. Thus, this work is a testimony to the sheer grit, determination and perseverance shown by PROJECT DEEPAK right from its early days. The subsequent major events in the history of Project Deepak include:- (a) In 1965, construction of the 122 Km long Road Dhami-Basantpur-Kiongal and 107 Km long stretch of Road Keylong-Sarchu (part of the Manali-Leh road) was entrusted to PROJECT DEEPAK. (b) In December 1966, following disbandment of Project Chetak, all roads of Uttaranchal were taken over by PROJECT DEEPAK. Thus, the 300 Km long Road Rishikesh –Joshimath-Mana, 63 Km long road Road Joshimath-Malari and 260 Km long Road Tanakpur-Askote-Tawaghat came under PROJECT DEEPAK. (c) The early seventies saw Project Deepak spreading its light (Deepak Jyoti) in the states of Rajasthan and even Punjab. -
