24 STUDIES OF PLANT LIFE. 
B. The Reproductive Portion. 
1. The little cups (cupules) may be observed to con- 
tain small, flat, green structures (brood buds or 
gemma). What is the location of the cupules. 
Are their edges complete? If not, where are 
they incomplete? Sketch one or more cupules. 
2. To what are the gemme attached (m.)? Are they 
few or numerous ? 
3. With l.p. find two lateral indentations (vegetative 
notches), also the place of attachment. Study the 
form and structure of agemma. What is its color 
and why? What food storage has it? (Make 
tests.) Sketch a gemma. 
4. Note the origin of erect stalks (pedicels) the distal 
expanded portions of which (receptacles) bear the 
gamete bodies. 
5. The receptacle having a scalloped margin bears the 
spermaries on its distal surface, and the receptacle 
having strap-shaped projections about its margin 
bears on its proximal surface inverted flask-shaped 
bodies called the archegonia (ovaries). 
6. An archegonium consists of a stalk, body, and neck. 
If possible, see and sketch. 
7. How do the thalli, which bear the fruiting structures 
and the vegetative ones, compare ? 
8. Note carefully any other structures on the proximal 
and distal surfaces of the receptacles. 
9. In some specimens the oospore (the fertilized gamete 
of an archegonium) may have grown, and in its 
development produced yellowish bodies (spores) 
and spiral structures (elaters). If so, use l.p. and 
study them. Sketch spores and elaters.
