The elements of a Random Forest Classifier in R

What is the "elements" of a random forest classifier in R?
Why does the "elements" always equal 19 no matter what data set, what number of features I use? For example, in my R Studio Environment:

Name of the R object         Description
rf_goodjunk                        Large randomForest.formula (19 elements, 24.9 Mb)
rf_more                              Large randomForest.formula (19 elements, 18.9 Mb)
rf_1                                    Large randomForest.formula (19 elements, 12.6 Mb)
rf_2                                    Large randomForest.formula (19 elements, 15.2 Mb)
rf_3                                    Large randomForest.formula (19 elements, 13.2 Mb)

Random forest returns a list objet, containing several elements which always will be 19 if the function return 19 elements.

The number you refer to describes the number of elements inside a precise list, and is not due to Random Forest particularly, but is a standard behavior.

For example, l <- lm(Sepal.Length ~ Sepal.Width, data = iris) returns a list of 12 elements : the coefficient, the residuals, etc...
