Caricaceos or Papaw Family. A family of latex-containing trees 

 composed of two genera indigenous to tropical America. Of chief 

 pharmaceutic interest is the species Carica Papaya, the Papaw or 

 Melon tree, the fruit of which yields Papain, a valuable digestive 

 ferment. This plant is a tree about 20 feet high which bears at its 

 summit a cluster of deeply lobed petiolate leaves and dioecious flow- 

 ers. The fruit is a berry, the size of one's head and contains an acrid 

 milky juice from which papain can be precipitated by the addition 

 of alcohol. 



Cistacece or Rock Rose Family. Herbs or shrubs whose stem and 

 branches are "of ten glandular, pubescent or tomentose, with simple 

 or stellate trichomes. Leaves simple, entire, the lower ones opposite, 

 upper alternate. Flowers perfect, regular, terminal, and solitary 

 or in cymes or unilateral racemes; sepals five, the two external ones 

 often bractiform or wanting; petals five (Helianthemum) rarely three 

 or none (Lechea); stamens hypogynous, indefinite; carpels three to 

 five, ovary free, one- celled. Fruit a one-celled, three- to five-valved
