Morphological and Anatomical Study of Bidens Pilosa Var.Pdf (440.3
1 Morphological and Anatomical Study of Bidens pilosa var. minor (Blume.) Sher. From Tribe Heliantheae Dr Ngu Wah Win1 & Min Htay Wai Linn2 Abstract In this research, morphology and anatomy of Bidens pilosa var. minor (Blume) Sher. of tribe Heliantheae belonging to the family Asteraceae were studied, photomicrographed and described. The plant is annual erect herb. Leaves are trifoliolate compound and the florets of rays and disc in a head are bisexual and monoecious heads are also found. In anatomical characters, although endodermis are inconspicuous only in roots, it is conspicuous in stem and root. The stomata types are anomocytic and vascular bundles are bicollateral, open and covered by one-layer of bundle sheath. The resulting characters are valuable for the identification of study species for further researchers. Key words – Asteraceae, endodermis, vascular bundles, bicollateral Introduction Asteraceae also called Sunflower family is one of the most important economic family and the second largest of flowering plant families. It consists of several tribes. Its flowers have two types of florets. Disc florets are in the center of head and ray florets in the outer. Many plants of Asteraceae family are economically important as weed, ornamentals, medicinal, green vegetables and poisonus plants. Commercially the flowers of this Asteraceae family are very famous of their colourful florets and beautiful petals. Several plants of this family are commonly cultivated for ornamental purpose in the gardens plots and field. The studied species of this Asteraceae family are native of America, Africa, India and all warmer countries (Grierson 1980). The study species is widely distributed in Pyin Oo Lwin of Mandalay Region. -

Box 299 St. Louis, Missouri 63166 ABSTRACT A new species, Munnozia ortiziae Pruski (Compositae: Liabeae: Munnoziinae), is described from the Andes of Pasco, Peru. It is most similiar to M. oxyphylla , also of Peru, in its pinnately veined, lanceolate to elliptic-lanceolate leaves and moderately large capitula in loose, open cymose capitulescences. KEY WORDS: Andes, Asteraceae, Compositae, Liabeae, Liabum , Munnozia , Munnoziinae, Pasco, Peru. Munnozia Ruiz & Pav. (Compositae: Liabeae: Munnoziinae) is an Andean-centered genus of more than 40 species (Robinson 1978, 1983). It was resurrected from synonymy of Liabum Adans. by Robinson and Brettell (1974) and differs from Liabum by black (vs. pale) anther thecae. A new species, Munnozia ortiziae Pruski, from the Andes of Pasco, Peru, is described herein. The new species appears most similar to M. oxyphylla (Cuatrec.) H.

Chromosome Numbers in Compositae, XII: Heliantheae
SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

The three species have traditionally been placed in a single genus but were recently divided into two ( Platycarpha and Platycarphella ). All have ‘secondary heads’ formed by tightly clustered heads on the crown of the rhizome. The three species are easily separated from one another based on characters such as leaf type, head size, style and corolla length, and pollen type. Morphological and molecular data support Platycarpheae as a monophyl- etic group within the subfamily Cichorioideae but no firm sister-group relationship has been determined. The three species form a monophyl- etic group on a long branch: Platycarphella carlinoides and Platycarphella parvifolia share more characters and are sister-taxa; Platycarpha glomerata has the largest number of unique features and is the sister taxon to the other two species. The distributions and flowering times of the three spe- cies are different. Platycarphella carlinoides is the most widespread of the species and grows in northwestern South Africa, the central highlands of Namibia, and southwestern Botswana; its peak flowering time is March-July. -
