| 2:56a | [Botany • 2022] Chamaecrista forzzae (Leguminosae) • Morphological Studies of Chamaecrista sect. Absus ser. Setosae With Emphasis on the Chamaecrista setosa Complex, including A New Species
Abstract Chamaecrista is one of the largest genera of Leguminosae, subfamily Caesalpinioideae. Traditionally, it has been divided into six sections, of which Chamaecrista sect. Absus is the largest, with 31 series. Chamaecrista sect. Absus ser. Setosae comprises nine species. Chamaecrista setosa is the most widely distributed species, comprising four varieties, distinguished by the type and distribution of glandular trichomes, and the leaflet venation. Given the importance of leaflet venation in the delimitation of the taxa, here we performed a study of leaflet architecture of all species of the series and a more detailed morphological study for the Chamaecrista setosa complex. For the study of leaf architecture, 2D images of the leaflets were made using the Faxitron x-ray technique. The morphological studies were based on herbarium specimens. We present the details of the leaflet architecture for the species of Chamaecrista sect. Absus ser. Setosae, and we propose nomenclatural changes for a variety of Chamaecrista setosa and some corrections to typifications. During our studies we also found a new species, Chamaecrista forzzae, which is morphologically similar to Chamaecrista setosa and Chamaecrista multiseta. It is here described and illustrated.

| 6:44a | [Botany • 2022] Centaurea lovricii (Asteraceae: Cardueae) • A New Species of Centaurea sect. Centaurea from Croatia
Abstract A new species, Centaurea lovricii, is described and illustrated from the island of Vis (Dalmatia, Croatia). It occurs on northwest-facing calcareous cliffs near the sea, where it grows with several other rare endemic species. Centaurea lovricii is morphologically similar to C. glaberrima and C. divergens of C. sect. Centaurea, from which it differs in having more succulent leaves with larger and less incised leaflets, bigger capitula, larger phyllaries with more developed appendages and denser and undulate fimbriae, larger florets, bigger achenes, and longer pappus. Its morphological features, distribution, ecology, conservation status and taxonomic affinities are examined. In addition, a new iconography and lectotypification for C. glaberrima and C. divergens is provided. Keywords: Adriatic region, Balkan flora, Centaurea, Croatia, morphology, new species, taxonomy 
 Centaurea lovricii Bogdanović, Boršić, Ljubičić, Brullo & Giusso, sp. nov. Etymology: This species is dedicated to the Croatian botanist Andrija–Željko Lovrić (1943–2018), who was the first to collect it and consider it as a new species.

| 7:47a | [Entomology • 2019] Prymnotomis cecidicola • A New Cecidogenous Species of Many-plumed Moth (Lepidoptera: Alucitidae) associated with Cordiera (Rubiaceae) in the Brazilian Cerrado
Abstract Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnotomis Meyrick, 1931 except for its original description that was based on a single male, the holotype of Prymnotomis crypsicroca Meyrick, 1931 from Espirito Santo, Brazil. We describe here a second species for this genus, Prymnotomis cecidicola sp. nov. whose larvae induce galls on Cordiera elliptica (Cham.) Kuntze (Rubiaceae), a dioecious plant with dimorphic inflorescences found in the Brazilian Cerrado, Planaltina City, Federal District. Adults, larvae, pupae and galls are illustrated under light and scanning electron microscopy. Galls are green, spherical, unilocular and develop individually on C. elliptica flower buds. During development they look like fruits in shape and colour but are larger, do not have style scars when on female plants, and are induced also in male inflorescences. Pupation occurs outside the gall within a silk cocoon, presumably in the litter. A preliminary analysis of DNA barcode sequences including putative members of other alucitid lineages and Neotropical BINs (Barcode Index Number) supports Prymnotomis cecidicola sp. nov. as an independent phylogenetic unit, with 12 to 18% divergence. Its nearest-neighbour was the BIN cluster 5 (BOLD:AAA0842) that includes specimens from Costa Rica. Key words: Alucitid moths, Brazilian Savanna, insect galls, Prymnotomis, taxonomy
  Prymnotomis cecidicola Moreira & Becker, sp. nov. Diagnosis: Prymnotomis cecidicola shares with the closely related Hexeretmis Meyrick the porrect maxillary palpi, forewing cleft only to 1/5 from termen, and pattern of wing venation. However, it differs from this genus in general appearance in coloration pattern and by presenting deeper hindwing clefts (ca 1/3 of wing length), as pointed out by Meyrick (1931). P. cecidicola can be separated from the congeneric P. crypsicroca Meyrick by the smaller size of the latter, whose forewing length of the type specimen measures ca 6 mm, and by the less contrasting coloration of P. crypsicroca, especially in relation to the hindwing. The basal process of the valva of the male genitalia is upturned, finger-like, covered with sparse filiform setae in P. crypsicroca, while in P. cecidicola it is turned down, looking like a claw, bearing short, stout spines on the base. Etymology: The species name is derived from the Greek kekis – idos = gall + the Latin co – col = with; to be treated as feminine.

| 9:07a | [Botany • 2024] Sedum xunvense (Crassulaceae) • A New Species from Southeast China
Abstract In this paper, Sedum xunvense is described as a new species from Zhejiang, Southeast China. Sedum xunvense is morphologically similar to S. formosanum, but the latter differs in clustered and robust stems (vs. solitary, slender), green or slightly red smooth stems and inflorescence rachises (vs. purple-red and ribbed), thick and succulent leaves (vs. thin), yellow anthers (vs. reddish-brown), erect follicles (vs. oblique), and is found in dry habitats in rock crevices (vs. damp ravines, rocks and mossy thickets). A reconstructed ML phylogeny of Sedum, based on nrITS sequence data, strongly suggests that S. xunvense forms an independent clade that is sister to a larger clade of many species, including S. formosanum.

| 2:34p | [Botany • 2024] Kaempferia sakolchaii (Zingiberaceae) • New Taxa from Northeastern Thailand
Abstract An examination of the diversity of Zingiberaceae in Thailand led to the discovery of two undescribed taxa within the genus Kaempferia: K. sakolchaii P. Saensouk, Saensouk & Boonma, a newly described species, and K. phuphanensis var. viridans P. Saensouk, Saensouk & Boonma, a novel variety. Additionally, our investigation encompassed the chromosome numbers, karyotypes, and pollen morphological characteristics of these taxa. Both taxa share a chromosome number of 2n = 22, accompanied by distinctive karyotype patterns. Kaempferia sakolchaii displays a karyotype of 12m + 10sm chromosomes, while K. phuphanensis var. viridans presents a karyotype of 10m + 10sm + 2st chromosomes. The pollen grains of K. sakolchaii and K. phuphanensis var. viridans are monads, spheroidal in shape, radially symmetrical, apolar, inaperturate, and exine sculpturing irregularly arranged elongated ornamentation elements with verrucate features. This comprehensive analysis provides valuable insights into the taxonomic classification of these two taxa, enriching our understanding of Zingiberaceae diversity in Thailand. Keywords: Kaempferia; new species; new variety; Sakon Nakhon; taxonomy; Thailand; Zingiberceae
Kaempferia sakolchaii P. Saensouk, Saensouk & Boonma sp. nov. Subgenus Kaempferia Kaempferia sakolchaii is similar to K. siamensis, but differs in that it has lamina that are narrowly ovate to broadly ovate, adaxially dark green alternated with silver or white longitudinal stripes, with small black dots along the margin, and abaxially pale green with small black dots (vs. K. siamensis having lamina sub-orbicular to orbicular, adaxially plain green, with small black dots only at the distal part, abaxially pale green without small black dots); anther crest c. 6 × 3 mm, bilobed, each lobe apex with four sub-lobes (vs. anther crest c. 5 × 2.5 mm, bilobed, each lobe apex acute); ovary c. 3 × 2 mm (vs. c. 4 × 2); and epigynous glands c. 3 mm long (vs. 6 mm long). Etymology: The specific epithet “sakolchaii” was bestowed in honor of Professor Emeritus Dr. Sumon Sakolchai, who has a high level of knowledge and skill in the field of pharmacy. Furthermore, he has made significant contributions to the field of pharmaceutical botany, both in Thailand and across the world. In addition, he makes essential contributions as a behind-the-scenes person, providing consistent assistance to researchers in botany and pharmaceutical sciences. Previously, he was the President of Khon Kaen University in Thailand, the President of the Pharmacy Council of Thailand, and currently acts as the President of Burapha University Council in Thailand. “เปราะอาจารย์สุมนต์” Piyaporn Saensouk, Surapon Saensouk, Thawatphong Boonma, Sarayut Rakarcha , Pathomthat Srisuk and Vincent O.
