1. Intraspecific and reciprocal pollinations were made with Rhododendron japonicum and R. mucronatum, and pistils were collected at established intervals after pollination. This material was sectioned and examined to observe rate of pollen-tube growth, fertilization, and subsequent seed development. 2. The azalea megagametophyte is typical of the Ericales. 3. Pollen-tube development is slow, and callose plugs occur frequently throughout the length of the tubes. Fertilization occurs about 96… 
Postpollination Reproductive Biology of Rhododendron prinophyllum (Small) Millais
TLDR
An extensive examination of selfing in three species of Rhododendron, in- cluding studies of self and cross pollen tubes, showed no differences in rate of pollen tube growth between the two, and a reduction in reproductive success at each developmental stage.
Reproductive timetable for the tropical Vireya rhododendron, R. Macgregoriae
TLDR
The reproductive development of Rhododendron macgregoriae F.v.M., Section Vireya (Ericaceae) has been followed from 10 days before anthesis to the production of mature germinable seeds about 145 days after anthesis, which shows both protandry and physical separation of pollen from the receptive stigma.
Pollen-tube hypertrophy in ovules of Solanum and Lycopersicon following interspecific crosses
TLDR
Pollen-tube hypertrophy represents a poorly understood, though easily identified, form of fertilization failure occurring within the ovule, and its conspicuous nature should provide a valuable opportunity to better study the nature of such fertilization failures in angiosperms.
Early events in the embryo sac after intraspecific and interspecific pollinations in Rhododendron kawakamii and R. retusum
TLDR
Ovules of Rhododendron kawakamii and R. retusum are anatropous, unitegmic, and tenuinucellate, with a typical eight-nucleate, seven-celled embryo sac, and fertilization normally occurs 4–5 days after pollination.
Development of ovule, megagametophyte and early endosperm in representative species of Rhododendron L. (Ericaceae)
TLDR
Differences may occur in time of enlargement, orientation of some mitoses, some cellular characteristics, amount of starch present and final size of megagametophyte.
Cross incompatibility between Rhododendron sect. Tsutsusi species and Rhododendron japonicum (A. Gray) J. V. Suringar f. flavum Nakai
TLDR
It is concluded that the variation in the propensity for the cross incompatibility existed in this intersubgeneric hybridization, and that it differed among individuals rather than among species.
Studies of Floral Morphology in the Ericales VI. The Diapensiaceae
TLDR
The stamens are characterized by having anthers with a well-developed endothecium, a glandular binucleate tapetum, single pollen grains that are probably two-celled at maturity, and lengthwise dehiscence-either longitudinal, oblique, or transverse depending on the orientation of the pollen sacs.
Crossability of Kurume Azaleas as a Seed Parent for Hybridizing with Rhododendron japonicum (A. Gray) J. V. Suringar f. flavum Nakai
Crossability of Kurume azaleas (Rhododendron obtusum (Lindley) Planch.) as a seed parents, to hybridize with R. japonicum (A. Gray) J. V. Suringar f. flavum Nakai was tested based on the number of
An embryological approach to the taxonomic status of Vacciniaceae
TLDR
The structure and development of male and female gametophytes, endosperm and embryo are described for vaccinium nummularia Hook, and the grouping of Vaccinioideae as a subfamily with the rest of Ericaceae is supported.
Variation in Crossability among Rhododendron japonicum f. flavum Plants as Pollen Parents when Crossed with Evergreen Species, R. eriocarpum
TLDR
The results suggest that it is important to select highly crossable R. japonicum f.

TLDR
A comparison of the characteristics of the Clethraceae, as exemplified by the three species studied, with those of other groups in the Ericales shows that the family is not so primitive with respect to the vascular anatomy of the flower as it is with respectto certain of its other morphological features.
