	Apetalous Chickweed
		Apetalous Chickweed was first identified in Illinois in 1985, and it has since established itself in several NE counties.
		Apetalous Chickweed is locally common in lawns along sidewalks and roadsides, sometimes forming sizable colonies.
		Apetalous Chickweed is similar to Stellaria meadia (Common Chickweed) in having ovate leaves, stems with lines of hairs, and a variable number of stamens in each flower.

		A new apetalous B. napus mutant was identified in a breeding nursery at AAFC-Saskatoon in 1996.
		The apetalous characteristic was strongly expressed at the early and full bloom stages, but late developing flowers had petals that were reduced in size and number.
		Seventeen completely apetalous plants were found that had normal plant vigour and developed normal sized leaves and self seed was produced on eight of these plants in the field.

		In apetalous line, except that the number of first effective branches increased and the height of plant, length of terminal raceme decreased significantly, location of effective branches become higher, Grains number per pod reduced.
		The apetalous line has a special protein 1, and quantity of protein 2 and 5 are higher than those of petalous line, while the quantity of the protein 3,4,6 are lower (Data not shown).
		Apetalous line has big pistil and anther that is advantageous to form big pods and pollinate, but it has some inferior agronomic traits.

	SUB Göttingen - Dissertationen - Jiang, Lixi : A mutant with apetalous flowers in oilseed rape (Brassica napus): ...
		Apetalous genotypes might be of interest in oilseed rape breeding because of their more efficient photosynthesis and reallocation of the photosynthesized assimilates and a lower probability of infection from pathogens distributed by petals.
		The mutant 'ap-Tengbe' with apetalous flowers and some breeding lines with complete or partial apetalous flowers were investigated for (1) the genetic regulation of apetalous flowers, (2) environmental effects, in particular the effect of some phytohormones, on expression of the petalous degree (PDgr), (3) the crop physiology, and (4) the infection from Sclerotinia disease.
		Crop physiology of an apetalous line with improved agronomic traits was compared with that of a partial apetalous and a normal petalled sister lines.

	Pistachio - Wikipedia, the free encyclopedia
		The plants are dioecious, with separate male and female trees.
		The flowers are apetalous and unisexual, and borne in panicles.
		The fruit is a drupe, containing an elongated seed (a nut in the culinary sense, but not a true botanical nut) with a hard, whitish shell and a striking light green kernel, having a very characteristic flavour.

	Chapter 3: Clover and Some Relatives
		The flowers of the lespedezas are of two types: petaliferous (or chasmogamous) and apetalous (or cleistogamous).
		In the apetalous flowers, the style is J-shaped (Clewell 1964), so that the stigma touches one or more anthers and selfing can occur.
		Hanson (1943) concluded that temperature is a strong factor because most of the flowers were apetalous on plants grown at 70deg F, but were petaliferous on plants grown at 80deg.

		The biogeography of the Sanguisorbeae (Rosaceae) is puzzling, with a fragmented and disjunct pattern of distribution, especially among the apetalous members of the tribe.
		A morphological phylogenetic analysis of the tribe Sanguisorbeae was conducted in order to clarify the relationships among the apetalous genera and between apetalous and petalous members of the tribe.
		Initial results indicate that the apetalous genera form a derived monophyletic clade while the petalous genera represent several basal lineages.

	INHERITANCE OF A MALE STERILE APETALOUS INFLORESCENCE IN ZINNIA ELEGANS
		This study was conducted to determine the inheritance of a male sterile apetalous inflorescence in Zinnia elegans.
		A variable number of recessive alleles were hypothesized to be present in the MF lines, with some being heterozygous.
		The apetalous and male sterile characters are very likely pleiotropic.

	Inflorescence Terminology (Part 1)
		It consists of a thickened, fleshy axis (spike) bearing clusters of sessile, apetalous, unisexual flowers.
		Catkin or Ament: A spike-like inflorescence of unisexual, apetalous flowers, often pendent and falling as a unit.
		Spadix: A thick, fleshy spike of unisexual, apetalous flowers, often surrounded by a vase-shaped or funnel-like modified leaf or spathe which is often brightly colored.

		The most recent classification of the genus by Lingelsheim (1920) identified two sections: Ornus (subsections Euornus and Ornaster), and Fraxinaster (subsections Dipetalae, Pauciflorae, Sciadanthus, Melioides, and Bumelioides).
		Ornus is characterized by terminal inflorescences, insect pollinated Euornus have showy petalous flowers and wind pollinated Ornaster are apetalous.
		The species of section Fraxinaster are wind pollinated and characterized by apetalous flowers in lateral inflorescences (except F.

		The leaflets can be lanceolate to oblong, with margins that may be separated into several shallow lobes.
		Boxelder is dioecious: the "male" plants bear stamens in umbel-like arrangements, while the "females" produce apetalous flowers in racemes.
		The fruits produced by the female plants are double samaras, or winged capsules composed of two easily-separable lobes.

	ARACEAE (Site not responding. Last check: 2007-11-02)
		This family belongs in the monocotyledons, although its leaves are often atypical in that they are often broad with netted venation.
		The inflorescence is very consistent in having a dense mass of apetalous flowers on a central spadix.
		The flowers are often enclosed in a leaf-like spathe which can be brightly colored.
