"Dicky is just right," laughed Helen. "That is a 'shield-shaped' leaf."
"Do the tips of the leaves have names?"
"Yes. They are all descriptive—'pointed,' 'acute,' 'obtuse,' 'truncate,' 'notched,' and so on," answered Helen. "Did you notice a minute ago that I spoke of the 'leaflet' of a horse-chestnut leaf? What's the difference between a 'leaflet' and a 'leaf'?"
"To judge by what you said, a leaflet must be a part of a leaf. One of the five fingers of the horse-chestnut leaf is a leaflet," Della reasoned out in answer.
"Can you think of any other leaves that have leaflets?"
"A locust?"
"A rose?"
"A sweetpea?"
