He, Z.-S., He, W.-M., Xu, L.-L., Shi, P.-L., Zhang, X.-Z., He, Y.-T., Zhong, Z.-M. & Dong, M. 2006: Are plants more responsive to decreased than to increased rainfall on the Tibetan Plateau? Evidence from Carex duriuscula subsp. stenophylloides. — Ann. Bot. Fennici 43: 401–408.

Carex duriuscula subsp. stenophylloides is a sedge species in alpine grassland ecosystems on the Tibetan Plateau. Here we examine its physiological and growth responses to variation in simulated rainfall in a growing season. Compared with the present local rainfall, increased rainfall had no effect on any measured trait except for long-term water use efficiency, and decreased rainfall significantly reduced total leaf area and biomass production, while only severe limitation of rainfall decreased net photosynthetic rate, stomatal conductance, transpiration rate, and apparent carboxylation efficiency. Net photosynthetic rate was significantly correlated with stomatal conductance, transpiration rate, apparent carboxylation efficiency, and leaf water potential. Total plant dry weight was significantly correlated with net photosynthetic rate, total leaf area, and leaf area ratio. These findings suggest that stomatal limitation and degraded activity of mesophyll cells result in a decrease in net photosynthesis, and that decreased net photosynthesis and total leaf area lead to a decrease in plant production. Based on our measurements, sedge-dominated ecosystems of the Tibetan Plateau are more likely to be impacted by decreases in growing season rainfall than by increases.

Juslén, A. 2006: Revision of Asian Herbertus (Herbertaceae, Marchantiophyta). — Ann. Bot. Fennici 43: 409–436.

Based on a study of approximately 1300 herbarium specimens, 12 species are recognized in the genus Herbertus Gray (Herbertaceae, Marchantiophyta) in Asia: H. aduncus (Dicks.) Gray subsp. aduncus, H. armitanus (Steph.) H.A. Mill., H. buchii Juslén sp. nova, H. ceylanicus (Steph.) Abeyw., H. circinatus (Steph.) H.A. Mill., H. dicranus (Taylor ex Gottsche et al.) Trevis, H. guangdongii P.J. Lin & Piippo, H. kurzii (Steph.) R.S. Chopra, H. longispinus Jack & Steph., H. pilifer (Steph.) H.A. Mill, H. ramosus (Steph.) H.A. Mill., and H. sendtneri (Nees) Lindb. Nine binomials are proposed as new synonyms. Herbertus subrotundatus X. Fu & Y.J. Yi does not belong to the genus Herbertus. The ranges of H. aduncus subsp. aduncus, H. dicranus, and H. sendtneri extend to other continents in addition to Asia. Four species are shared by Asia and Australasia. The distribution areas of five species are restricted to Asia. Of those five, two are known only from their type localities: H. buchii from Amur province, Russia, and H. guangdongii from Hainan Island, China. A key to the species is presented. Descriptions, illustrations, and distribution maps are presented for each species.

Xiao, D.-X. & Xu, F.-X. 2006: Megasporogenesis and development of female gametophyte in Manglietia decidua (Magnoliaceae). — Ann. Bot. Fennici 43: 437–444.

Manglietia decidua (Magnoliaceae) is the only deciduous species known in the genus. The ovules are anatropous, bitegmic and crassinucellar. The archesporium is one-celled and of hypodermal origin. The chalazal megaspore is functional and develops into the Allium type of female gametophyte. There is apparently a delay in development of the embryo while the endosperm is developing. As a cell wall partitioned the two nuclei into the first two endosperm cells, endosperm development was ab initio cellular. In the seed the outer integument became differentiated into an outer fleshy layer and an inner stony one, the inner integument persisting only at the micropylar region and forming a plugging tissue.

Chang, Z.-Y., Xu, L.-R. & Shi, F.-C. 2006: Caragana qingheensis (Fabaceae), a new species from northwestern China. — Ann. Bot. Fennici 43: 445–447.

Caragana qingheensis Z.Y. Chang, L.R. Xu & F.C. Shi sp. nova (Fabaceae) is described and illustrated from Xinjiang, China. It is similar to C. camilli-schnederi Kom. by sharing the hairy leaflets and pods, but differs in its much smaller leaflets and flowers, calyx teeth 1/2 to 2/3 the length of tube, and longer wing auricle. It belongs to Caragana ser. Frutescentes and is only known from its type locality to date.

Verbascum yurtkuranianum Kaynak, Da?kin & Yilmaz sp. nova is described and illustrated from northwest Anatolia, Turkey. It is closely related to V. bugulifolium, from which it differs mainly in the shape of leaves, color, corolla diameter and capsule shape.

Zhu, R.-L. 2006: On Cheilolejeunea tenella (Jungermanniopsida: Lejeuneaceae), a poorly known species from Singapore. — Ann. Bot. Fennici 43: 484–487.

Cheilolejeunea tenella (Taylor) J.J. Engel & B.C. Tan (Lejeuneaceae) has a proximal hyaline papilla of the leaf lobule and other typical characters of the genus Lejeunea. It is reinstated here as Lejeunea tenella Taylor. The species has to be excluded from the floras of Indonesia, New Zealand, and the Philippines because previous reports of Cheilolejeunea tenella for these countries are based on misidentifications. The description and illustrations of Lejeunea tenella here provided are based on the type specimen from Singapore.
