刮目相看茜草科（上）

蓬子菜茜草科植物有５００属６０００种,也有书记载为６３７属１０７００种。它在被子植物的科中不是最大的,但是有一现象十分有趣。如果我们把几个大科的属和种数对比一下,会发现茜草科有一特点,即用属数和种数比,平均每属所包含的种数少,足以令人刮目相看这一科。茜草科以种数与属数相除,平均每属含种数１２个,此数值较之其他几个大科少得多。这说明茜草科植物属的分化强烈,亦即说明本科生物多样性的分化更深入。但是茜草科中也有一些大的属,如九节木属Ｐｓｙｃｈｏｔｒｉａ有８００—１５００种,耳草属Ｈｅｄｙｏｔｉｓ…

Argostemma bachmaense (Rubiaceae,Rubioideae, Argostemmateae), a new species from central Vietnam

Argostemma bachmaense, a new species from central Vietnam, is described and illustrated here. The new species is most similar to A. laoticum and A. vietnamicum but can be distinguished from the latter two by having a well-developed internode with leaf pairs separately arranged along stem, isophyllous or slightly anisophyllous leaves, an oblanceolate to spatulate lamina with attenuate base and lateral veins with 4–5 pairs prominent on abaxially, a terminal, solitary flower, an absent bract, narrowly ovate or broadly lanceolate, 8.5–10.5 × 2.8–4.2 mm petals, 6.5–7.5 mm long stamen with yellow anther, a 8.5–9.5 mm long, exerted style and a globose stigma. Information on ecology, phenology and preliminary conservation assessment of the proposed new species are provided. In addition, we also provide an identification key to the nine Argostemma species found in Vietnam.     

Agouticarpa, a new neotropical genus of Tribe Gardenieae (Rubiaceae)

Agouticarpa, a new genus of the informalAlibertia group (Rubiaceae), is described and illustrated. It comprises six species, and occurs from Costa Rica to Bolivia. Three species are here described as new:Agouticarpa grandistipula, A. hirsuta, andA. velutina. Additionally, three new combinations are made:A. curvifolia andA. williamsii (previously inGenipa) andA. isernii (previously inAlibertia). Agouticarpa is characterized by being dioecious, having elliptic to abovate, membranaceous stipules, male flowers in a branched dichasial or thyrse-like inflorescence, a poorly developed cup-shaped calyx, pollen grains with 3–7 apertures, and large globose fruits.

Riodocea (Rubiaceae, Gardenieae), a new genus from the Brazilian Atlantic forest

The genusRiodocea is here described from material collected in the várzea forest of the Rio Doce Valley, northern Espírito Santo.Riodocea is a monotypic genus probably related to the Amazonian endemicKutchubaea. A line drawing shows general morphology and photomicrographs show pollen morphology ofRiodocea pulcherrima. Distribution maps ofRiodocea andKutchubaea are included. The valley of the Rio Doce is here included in the Bahian Hylaea, defined as a subregion of the Brazilian Atlantic forest. The connections between the Amazonian Hylaea and the Bahian Hylaea are discussed.

Systematic wood anatomy of the tribe Guettardeae (Rubiaceae)

Systematic wood anatomy of the tribe Guettardeae (Rubiaceae). The wood anatomy of nearly all genera of the Guettardeae (Rubiaceae, Guettardoideae) has been examined, and in this respect the tribe is heterogeneous. Suggestions are made for a delimitation of the tribe. Guettarda, Bobea, Antirhea, Malanea and Chomelia Jacq. are sufficiently similar in their wood anatomical characters to warrant retention in the same tribe. Machaonia, Timonius and Dichilanthe are anomalous. Suggestions are given for taxonomic revisions of some genera based on their wood anatomy.
