Sapria himalayana (Rafflesiaceae) from Mizoram

         Griffith (1844) established the genus Sapria with a species S. himalayana (Rafflesiaceae) from Mishmi Hills of erstwhile Assam, now in Arunachal Pradesh. This genus consists of three species, viz., S. himalayana Griff., S. poilanei Gagnep. and S. ram Banziger & B. Hansen and is confined to Southeast Asia with restricted disjunctive distribution.

         Burkill (1924) enlisted S. himalayana in his paper on the Botany of Abor
Expedition. Abor hills are now in Siang districts of Arunachal Pradesh. Bor
(1938) reported the species from Aka Hills, now in Kameng district of Arunachal
Pradesh. Kanjilal & al. (1940) cited the collections of Burkill (from Khasia
Hills, N.E.F. Tract) and Bor (from Balipara Frontier Tract). Deb (1961) reported
this species from Koupru in Manipur. Adhikari & al. (1983) treated it as a
rare and endangered species in the Namdapha National Park. Chauhan (1987)
included Arunachal Pradesh (Namdapha), Manipur and Meghalaya under
its distribution, and categorised it as a rare species. Bhaumik & al. (1997)
recorded this species from Mehao Wildlife Sanctuary, Arunachal Pradesh.
This species was also collected from Kopli Hydroelectric area in N. Cachar
hills of Assam by Barua during 2006 - 2008.

           In 2013, Pandey, Singh, Sinha & Verma  have recorded S. himalayana, for the first time from Mizoram. Plants were seen in blooming on the shaded forest floor with moist humus soil in the Tawi Wildlife Sanctuary, Aizwal, located in the northeastern part of the state at altitudes ranging from 400 to 1700 m. The fleshy, globose flower buds of this root-parasite are visible only when they emerge from the soil. The flowers persist for 2 - 3 days after blooming and emit a putrid odour. They are unisexual, c. 20 cm in diam., and bright red in colour with sulphur yellow spots. Gradually they become dark and then decompose slowly. In Mizoram, it flowers during November to December.

CYCADACEAE

Cycas beddomei Dyer

Common English names : Beddome's cycas, Cicas di Beddome.

Vernacular names : Tel.: Perita, Madhana - Kamakshi.

Trade name : Andhra Pradesh Cycas, Cycad.

Distribution : This species is the global endemic of Seshachalam hills (formerly called as Cuddapah -
Tirupati hills) of the Southern Eastern Ghats of Andhra Pradesh.

Habitat : They occur in dry deciduous forests and on the exposed quartzite rock and sandy black soils in valleys of Tirupati hills at altitudes between 300 - 1100 m; along the rock strewn holy streams of the Tirumala in association with Phoenix pusilla Gaertn., Decaschistia cuddapahensis T.K. Paul & M.P. Nayar, Gardenia gummifera L. f. and Pterocarpus santalinus L.f.

Population status/Cause for RET : Endangered (B. Ravi Prasad Rao, Medplant 5: 11-12. 2012). Destruction of natural habitat, forest clearing and over exploitation of the species has resulted in its declination. Selective removal of female plants by some collectors as the cones are more attractive and fetch a higher price which upsets the male to female plants ratio.

Description : Shrubs to 2 m high, dioecious; bark brown, exfoliating in rectangular scales. Leaves up to 1 m long; rachis quadrangular, petiole up to 15 cm long with minute spines on upper portion, base clothed with tufted tomentum; leaflets narrow, linear, 10 - 18 x 0.2-0.35 cm, margins revolute, apex pointed. Male cone oblong-ovoid, up to 35 x 16 cm with a short peduncle; microsporophyll oblong, deltoid, tapering, acuminate at apex, lower erect, upper strongly recurved. Megasporophylls ovate-lanceolate, up to 4 x 2 cm; ovules usually 2 - 4. Seeds globose.



Medicinal properties and other uses : Seeds edible. The seeds are processed and eaten in mixture with
‘Ragi’ cereal. Crude flour made out of the endosperm of the seeds of this plant is used as one of the
ingredients in the preparation of Sweet and Dhosa. The male cones are pruned away by local tribals for its professed medicinal properties and are used as a major ingredient in rejuvenating tonics. The male cones of this plant are also considered to possess the narcotic properties like that of C. circinalis. Further, this plant is horticulturally valued due to the palm-like appearance. The male cones of this plant are used by local herbalists as a cure for rheumatoid and muscle pains. The seeds are ground to a paste with coconut oil and are used as a poultice to treat skin complaints such as wounds, sores and boils.

Parts used commercially : Pith, Cones.

Commercial/Ex-Im data : It is learnt from the local people that male cones of C. beddomei are collected and sold in Chennai market for a maximum of Rs. 1,000/- per cone.

Legal : Listed in Appendix II on 4.2.1977, included in Appendix I w.e.f. 22.10.1987. Also included in
'Schedule VI' of the Wild Life (Protection) Act 1972 of India.

Chlamydomonas nivalis causing Watermelon snow

Watermelon snow, also called snow algaepink snowred snow, or blood snow, is Chlamydomonas nivalis, a species of green algae containing a secondary red carotenoid pigment(astaxanthin) in addition to chlorophyll. Unlike most species of fresh-water algae, it is cryophilic (cold-loving) and thrives in freezing water. Its specific epithet, nivalis, is from Latin and refers to snow.
This type of snow is common during the summer in alpine and coastal polar regions worldwide, such as the Sierra Nevada of California. Here, at altitudes of 10,000 to 12,000 feet (3,000–3,600 m), the temperature is cold throughout the year, and so the snow has lingered from winter storms. Compressing the snow by stepping on it or making snowballs leaves it looking red. Walking on watermelon snow often results in getting bright red soles and pinkish pant cuffs.

History

Watermelon snow streaks.
The first accounts of watermelon snow are in the writings of Aristotle. Watermelon snow has puzzled mountain climbers, explorers, and naturalists for thousands of years, some speculating that it was caused by mineral deposits or oxidation products that were leached from rocks.
In May 1818, four ships sailed from England to search for the Northwest Passage and chart the Arctic coastline of North America. Severe weather made them finally turn the ships back, but the expedition made valuable contributions to science. Captain John Ross noticed crimson snow that streaked the white cliffs like streams of blood as they were rounding Cape York on the northwest coast of Greenland. A landing party stopped and brought back samples to England. The Times wrote about this discovery on December 4, 1818.
A follow-up article three days later erroneously concluded that the coloration was caused by meteoric iron deposits.
When Ross published his account of the voyage in 1818, it contained a botanical appendix by Robert Brown. In it, Brown tentatively attributed the red snow to an alga.
The phenomenon was also reported from the Scottish Highlands in the nineteenth century and subsequently recorded scientifically from a snowpatch in the Cairngorm Mountains in 1967.[5]

Chlamydomonas nivalis

Chlamydomonas nivalis is a green alga that owes its red color to a bright red carotenoid pigment, which protects the chloroplast from intense visible and also ultraviolet radiation, as well as absorbing heat, which provides the alga with liquid water as the snow melts around it. Algal blooms may extend to a depth of 25 cm (10 inches), with each cell measuring about 20 to 30 micrometers in diameter, about four times the diameter of a human red blood cell. It has been calculated that a teaspoon of melted snow contains a million or more cells. The algae sometimes accumulate in "sun cups", which are shallow depressions in the snow. The carotenoid pigment absorbs heat and as a result it deepens the sun cups, and accelerates the melting rate of glaciers and snowbanks.
During the winter months, when snow covers them, the algae become dormant. In spring, nutrients, increased levels of light and meltwater, stimulate germination. Once they germinate, the resting cells release smaller green flagellate cells which travel towards the surface of the snow. Once the flagellated cells reach the surface, they may lose their flagellae and form aplanospores, or thick-walled resting cells, or they may function as gametes, fusing in pairs to form zygotes.
Many species feed on C. nivalis, including protozoans such as ciliatesrotifersnematodesice worms and springtails.
